The Spanish passenger railway market saw the entrance of two competitors in 2022–2023: the full-service operator Iryo and the low-cost operator Ouigo. Using a unique dataset of Spanish ticket price collected throughout an entire year and the Diff-In-Diff method, this paper investigates the impact on incumbent's prices of newcomers' entrance on the less congested corridors Madrid - Alicante and Madrid - Malaga/Sevilla. The Spanish government's strategy seems to be successful: the decision to lead the liberalisation process and the choice of having up to three asymmetric competitors induced a significant decrease in price even on the less attractive corridors, stimulating the demand and addressing the problem of under-utilization of some high-speed infrastructure. The results show that prices decreased by 28%–30% after nine months of competition. The impact has been the same on both the analysed corridors, despite the competition environment has been different in terms of number of competitors, pricing strategy and market share of those. • Spain is the first country with three competitors in the high-speed railway market. • Competition in high-speed rail in Spain reduced prices by 28%–30% in nine months. • The impact on incumbent's first-class and second-class prices was the same. • Both low-cost and full-service competitors similarly affected incumbent pricing.

Estimating line impedance is relevant in transmission and distribution networks, in particular for planning and control. The large number of deployed PMUs has fostered the use of passive indirect methods based on network model identification. Electrified railways are a particular example of a distribution network, with moving highly dynamic loads, that would benefit from line impedance information for energy efficiency and optimization purposes, but for which many of the methods used in industrial applications cannot be directly applied. The estimate is carried out onboard using a passive method in a single-point perspective, suitable for implementation with energy metering onboard equipment. A comparison of two methods is carried out based on the non-linear least mean squares (LMS) optimization of an over-determined system of equations and on the auto- and cross-spectra of the pantograph voltage and current. The methods are checked preliminarily with a simulated synthetic network, showing good accuracy, within 5%. They are then applied to measured data over a 20 min run over the Swiss  16.7  Hz railway network. Both methods are suitable to track network impedance in real time during the train journey; but with suitable checks on the significance of the pantograph current and on the values of the coefficient of determination, the LMS method seems more reliable with predictable behavior.

Historian Raul Hilberg once observed of death trains: "It's just very regular traffic. Death traffic". Though subtle, his insinuation that this death traffic represented a "new normal" is, in fact, an astute observation of a largely unresearched process whereby Polish railway workers, and locals living near railway tracks, became witnesses to the Holocaust through observing the distinctive new "traffic" flowing by their spaces of home and work. In this case study, therefore, I examine these "death traffic witnesses" to reveal how their experiences highlight a critical reality about genocide in our modern world – its ability to transform relatively banal spaces (in peacetime) into horrific ones when employed for sinister purposes. In this case, those banal spaces are the railways that cut through our modern landscapes as symbols of connection, commerce and transport; their steel rails cutting through backyards and city centres linking even remote villages with major metropolises.

A novel method is proposed for rail fastener detection based on millimetre‐wave (mmWave) radar, mmWave radar fastener counter (MMW‐FC), which can accurately detect and record the fasteners in real‐time as the train traverses its route. Under circumstances where GNSS signals remain unavailable for prolonged durations, precise train localisation can be accomplished by correlating the number of fasteners derived from this method with the corresponding track map. Initially, MMW‐FC utilises fast Fourier transform and adaptive beamforming to focus the energy reflected from fasteners. Subsequently, it applies an adaptive template‐matching algorithm to detect each fastener. Furthermore, by leveraging known fastener spacing and the average time for trains to pass adjacent fasteners, the Kalman filter can execute precise speed tracking, used as a speed reference when adjusting the matching template adaptively. The experimental results indicate that the proposed method can precisely count the fasteners the train encounters in diverse road and speed conditions. The fastener counter maintains the Counting Error less than 0.067%, the speed error stays below 1.8 km/h, and the maximum values of the mean absolute error and root mean square error for speed are 0.7337 and 0.9584 km/h, respectively.

Prior studies indicate that expanding the length of roadways and railways has a beneficial effect on economic performance. Nevertheless, the requirement for land transport infrastructure, which offers different degrees of accessibility and mobility, to facilitate economic expansion differs based on a country's stage of development. The present study has two objectives. Firstly, it is essential to ascertain the required investment for different types of land transport infrastructure to facilitate different stages of economic performance. Secondly, the objective is to examine the impact of different forms of land transportation infrastructure on economic performance by means of urbanization and exports. To highlight these concerns, a fixed-effects panel linear regression analysis was conducted on a panel consisting of 50 countries spanning the years 1980–2018. In countries with lower levels of urbanization and exports, improvements to road infrastructure, especially roads with high accessibility, are of greater importance for economic performance compared to the improvement of railways. Nevertheless, as urbanization and exports rise, the comparative impact of improvements in road infrastructure on economic performance in relation to improvements in railway infrastructure diminishes. Railway improvements have a more significant effect on economic performance compared to road improvements, owing to increased urbanization and export rates. During these stages of development, high-mobility roads are more crucial for economic performance compared to high-accessibility roads. The conclusion of the research examined a variety of policy recommendations derived from our findings, which are applicable to different levels of urbanization and exports. • Evaluate the economic benefits of various land transportation infrastructure. • Assess the capital needed for various transport infrastructure to help the economy. • Low urbanization and export require high-access roads to boost economy. • High urbanization and export require railways to boost economy.

In this article, we analyse India's transport sector policy. The study examines the two important modes of transport, viz., road and rail, and analyses the efficiency of transport infrastructure from 2011 to 2019. Through Data Envelopment Analysis (DEA), we evaluate modes in terms of the capacity of registered road goods vehicles and railway goods wagons, truck km/train km and energy consumption and corresponding freight traffic. The analysis gives valuable insight into the fact that rail infrastructure is more efficient than road infrastructure. Still, current transport sector policies promote energy-intensive carbon-fuel road vehicles rather than energy-efficient alternative transport modes. The study suggests the changes that may be incorporated in inputs to improve the efficiency of the road infrastructure. The Data Envelopment Analysis (DEA)-Malmquist Index analysis reports the need for total factor productivity improvement in rail transport and the introduction of technological innovations in road and rail transport sector management. The study employs a well-to-wheel (WTW) based index to ascertain the energy consumed and pollutants emitted by freight-carrying road and rail modes between two leading business hubs of India, i.e., Ludhiana and Mumbai. The paper identifies policy gaps and suggests a holistic approach for need-based roadway investment and a time-bound development of railway infrastructure in India. Our study generates valuable implications for India's policy planners and government authorities and provides new insights to other countries. • The study examines road and rail transport, and analyses the efficiency and energy consumption of these modes. • The study suggests the changes to improve the efficiency of the road infrastructure. • The Data Envelopment Analysis (DEA)-Malmquist Index analysis and well-to-wheel (WTW) based index have been employed for the analysis. • The paper suggests a need-based roadway investment approach and a time-bound development of railway infrastructure.

This paper explores the multifaceted cultural history of ghost trains in Victorian fiction by situating three little-known ghost stories in the publishing and social history of the second half of the nineteenth century. The figure of the ghost train offers a route into the entangled history of publishing and railways by contextualising the anxieties presented in railway ghost stories with the real-world experiences of passengers. Taking ideas of mobility as a focal point, this paper brings together discussions of virtual travel and the supernatural to demonstrate some of the impact railways had on reading and writing about train travel. More so than tales of other haunted transport technologies, it is the ghost train's unnatural capacity for movement that disturbs both passengers and readers. By both enhancing and warping reality, railways are ripe source material for Victorian ghost stories to entertain and demand questions of spatio-temporal experience from their reading passengers.

The article reappraises nature of technology transfer in a colonial context by underlining how the colonised mediated and shaped what was ostensibly an imposition by the imperial administration. This wider point is illustrated by demonstrating the ways in which in the late nineteenth and early twentieth centuries, different groups of Indians used newly introduced railways to reconceptualise meanings of travel by adding new categories of travel while significantly modifying the extant ones. Crucially deviating from both ‘technology as imperialism’ and ‘technology as subversion’ historiographical paradigms, this article argues for a more nuanced appraisal of technology transfer, especially emphasising the role of users in shaping the impact of technology. Examining a diverse range of sources, viz., railway records (Annual Railway Reports and railway passenger statistics), newspaper reports and travelogues and pamphlets written by Indian railway travellers, the article claims Indians not only mediated the impact of trains on travel in late colonial India; but they shaped the outcome of this technology transfer in ways that reveals agency and remarkable involvement with a new mode of transit. In short, the article demonstrates dynamic interaction between imperial policies and responses of the colonised through the lens of technology transfer. [ABSTRACT FROM AUTHOR]

The Belt and Road Initiative (BRI) is important to China's development vision. Under the BRI, Chinese policymakers have focused on exporting railway systems to developing countries, yet progress on some projects remains limited. This article focuses on delays associated with a planned railway project in Pakistan: the ML-1. It answers the following question: What explains delays in the ML-1 railway project despite strong Chinese interest in it? The article uses a two-step conceptual framework to answer this question. In the first step, it highlights the role of railway bureaucrats involved in project-level negotiations. It shows that local bureaucrats contribute to delays by actively negotiating technical parameters. Chinese firms have limited policy levers to ensure their acquiescence. In the second step, the article places delays in the context of Pakistan's political economy by analysing the role of the political and military elite. It also explores the impact of political change and economic factors on the project. Projects not in sync with the local political elites' development vision face delays. Domestic political changes also contribute to delays. Furthermore, a failure to gain major veto actors' support, coupled with economic problems and differences over financing terms, constrains China's ability to pursue large-scale projects.

The measurement of the longitudinal rail profile is relevant to the condition monitoring of the rail infrastructure. The running surface is recognizable as a shiny metallic area on top of the rail head. The detection of the running surface is crucial for vehicle-based rail profile measurements, as well as for defect detection. This paper presents a methodology for the automatic detection of the running surface based on a laser profilometer. The detection of the running surface is performed based on the light reflected from the rail surface. Three rail surfaces with different surface conditions are considered. Supervised machine learning is applied to classify individual surface elements as part of the running surface. Detection by a linear support vector machine is performed with accuracy of > 90 % . The lateral position of the running surface and its width are calculated. The average deviation from the labeled widths varies between − 1.2 m m and 5.6 m m. The proposed measurement approach could be installed on a train for the future onboard monitoring of the rail network. [ABSTRACT FROM AUTHOR]

Increased demand on rail, due to climate initiatives and passenger numbers, places significant pressure on existing railway operations; specifically on capacity, operational flexibility, and network robustness. These pressures are exacerbated by constraints, which prevent the construction of new track and infrastructure. This results in the need to use existing infrastructure and operating processes. One proposed solution is digitalization, which results in autonomous rail, where automated and connected intelligent transport systems facilitate smart traffic management. However, this generates the challenge of integrating autonomous trains and their associated technologies with existing infrastructure and operations. To understand this issue from an enterprise level, this paper has applied Brian Wilson's Soft Systems Methodology (a variation of Checkland's methodology) to the problem situation. This methodology explores and investigates the existing rail system in Great Britain (UK less Northern Ireland) and its stakeholders. The paper aims to propose a solution into how to transform the legacy system into one which incorporates autonomous operations and ultimately becomes fully autonomous. It culminates in a series of models that are relevant to those with a legitimate interest in the system. The models identify the activities required to analyze whether autonomy is worthwhile and if it is, how to successfully integrate it with legacy operations. Additionally, the models provide the basis for which a formal stakeholder analysis can take place. [ABSTRACT FROM AUTHOR]

Huge regenerative braking (RB) energy is generated in the AC traction power supply system (TPSS) which is related to safe operation and comprehensive energy utilisation. For the RB energy utilisation, the authors propose a railway regenerative braking power conditioner (RBPC) with no energy storage system (ESS) integrated which is located at the end of the power sections between adjacent traction substations (TSSs). First, the RB characteristics are studied based on a large amount of measured data, and the load power states are classified according to the load powers of adjacent power sections. Then, the RB energy utilisation scheme, transferring the RB power to the adjacent power section where traction power exists, has been studied. Moreover, a dual closed‐loop control strategy for a back‐to‐back converter is adopted to achieve RB energy utilisation. Finally, a case study and an engineering application are carried out. The results have verified the feasibility of this method, which can illustrate that more than half of the RB energy can be mutually utilised in adjacent power sections. [ABSTRACT FROM AUTHOR]

In the winter of 1941, the Red Army faced a shell crisis brought on by the loss of its pre-war stocks due to the rapidity of the German advance that summer, the dislocation of industry due to evacuation to the Urals, and the large expansion in the size of the army. Materiel shortages during the battle for Moscow forced reform in both the approach to and administration of handling all manner of supplies. This saw the introduction of strict rationing of munitions supplies at the Front level, and the centralization of munitions distribution and stocks by the Rear in the Centre Bases of the NKO.1 This use of a centralized supply system allowed the Red Army to use a 'just in time' approach to supplying the Fronts that enabled it to make maximum use of a limited number of supplies and to maintain a high tempo of operations.

This paper addresses the theme of communications between the province of Mato Grosso and the Atlantic through the territory of the province of Paraná, using as sources, preferably, the reports of the presidents of the two provinces, and having as a background the concerns of the Brazilian national state due to the remote and border condition of Mato Grosso. It is shown that the routes sought were initially terrestrial-fluvial and, later, rail-fluvial, and that the leaders of Paraná had a greater interest in such communications than their counterparts in Mato Grosso. In addition to envisioning the possibility of Paraná becoming the "emporium" of Mato Grosso commerce, those leaders also sought the benefits brought to their province by the central government's investments in roads to Mato Grosso.

With the rapid development of high‐speed railway, the auto‐transformer traction network (ATN) is also expanding. However, due to the improved performance of electric multiple units (EMUs) and the non‐linear relationship between impedance and ground fault distance, distance protection has limited coverage and cannot accurately locate the fault distance by measuring impedance. This paper presents a model of the ATN considering the presence of EMUs, which effectively demonstrates the characteristics of current distribution under the ground faults. Furthermore, a ground fault identification method based on multi‐terminal currents is proposed to enhance the accuracy of fault identification and differentiate faults and EMUs. The mapping relationship between current distribution and fault location is derived, and an accurate fault location method is proposed. Compared to existing methods, this method is not affected by EMUs and AT parameters. The fault identification and location scheme for ATN employs multi‐terminal synchronous information. Finally, through simulation and experimental setups, case studies have been conducted to verify the accuracy and robustness of the proposed method in various fault scenarios. Certainly, this research has significant application prospects in fault analysis and detection for HSR. [ABSTRACT FROM AUTHOR]

The importance of mobility in Canada's history can hardly be overstated. The built waterways, railways, and roadways that allowed for the movement of peoples, goods, and ideas within the country have long been considered cultural icons conveying collective ideas of Canadian identity. Yet, little has been written on the history of the modern construction machines that made this mobility infrastructure possible after Confederation, along with their designers, manufacturers, and operators. This article helps fill that gap by examining the technological development, manufacturing, and commercialization of earthmoving equipment in Canada (especially Ontario) in the 1860s-1920s, a period of great construction activity, including two of the world's largest civil engineering and earthmoving projects and one of the fastest-expanding road networks in North America. It discusses the role of the federal, provincial, and municipal governments in developing, adopting, and disseminating this technology, and their ultimate reliance on American manufacturers despite the National Policy's protectionism. This article supports the argument that technological development in Canada during the Second Industrial Revolution was continentally integrated in ways that involved technological dialogue with American companies, associations, and publications. While this manufacturing sector became dominated by American corporations by the First World War, the extent to and manner by which that happened varied depending on the type of machinery and the construction sectors in which they were used. The technological transition from steam-powered machines to electric, gasoline, and diesel motors and how it impacted Canadian manufacturers are also discussed. [ABSTRACT FROM AUTHOR]

As per the African Union's 2016 prescription, most new rail projects in Africa are greenfield standard gauge railways (SGR) that cost billions of dollars, which, if successfully implemented and well run, can offer better services than road transport. However, to be viable, SGR investments must have adequate freight traffic, provide reliable services, and charge much lower tariffs than the trucking industry. This means that SGRs will very likely have to be subsidized, which most African governments cannot afford to do. Based on the rail economics for SGRs, this article argues that it would be more feasible for most African countries to invest in upgrading and expanding brownfield rail infrastructure in the short-tomedium term. Using Kenya's Nairobi-Naivasha SGR as a case study, this article contextualizes and critically analyzes the greenfield vs. brownfield rail infrastructure debate that underpins Africa's railway renaissance and demonstrates that SGR investments may not necessarily be the most feasible rail projects for developing African economies.

This paper is the biography of a failed infrastructural project: that of building a Romanian seaport and of linking it to the mainland via a canal and/or a railway. It details its rich life, its initiators and partisans, but also its (mostly foreign) contenders; "born" in the early 1860s in a certain geopolitical, economic or infrastructural environment, the initiative morphed in the coming years in close connection and in direct competition with complementary or rival projects. While the plan of having an "independent" Romanian Black Sea port remained central to the Jibrieni project, most of its other infrastructural components were continuously reimagined, so as to fit into the Romanian government's priorities and – with them – into the extremely dynamic transportation map of Central and Eastern Europe in the 1860s–1870s.

The road system built during the Roman Empire continues to have a significant impact on modern infrastructure in Italy. This paper examines the historical influence of Roman roads on the development of Italy's motorways and railways. The empirical analysis demonstrates how modern Italian transport infrastructure largely follows the path of the consular trajectories established by the network of Roman roads. These ancient roads, being paved and connecting the extremes of the Italian peninsula, have endured over time, serving as the foundational physical capital for the development of the current transport network. Overall, this research highlights the enduring legacy of the Roman road system and the robustness of Roman roads as an instrument in determining the causal effect of modern infrastructure.

Brake pads significantly affect the braking performance of railways under both normal and emergency operating conditions. In previous studies, brake pads were made using the hand lay-up method and produced the best properties on specimens with epoxy, rice husk, Al2O3 and Fe2O3 compositions of 50%, 20%, 15% and 15%. However, the resulting density does not meet the density standard set by PT Industri Kereta Api Indonesia (PT INKA), which is 1.7–2.4 g/cm³. To date, there has been limited research into the utilization of the compression hot molding method for the production of asbestos-free composite friction materials composed of epoxy, rice husk, Al2O3 and Fe2O3 for railway applications. In this study, we aimed to determine the effect of compression molding temperature on the characterization of composite brake pads for railway applications. The brake pad specimens were made of epoxy resin, rice husk, Al2O3 and Fe2O3 with a composition of 50%, 20%, 15% and 15%, respectively. The manufacture of composites in this study used the compression molding method with a pressure of 20 MPa for 15 min holding time. The mold temperature used were 80, 100, 120 °C. Density, hardness, tensile, wear, thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC) tests were performed to evaluate the properties of the specimens obtained. The results demonstrated that an increase in molding temperature improved the characterization of the brake pads, with the best results achieved at a molding temperature of 120 °C (SP-3 specimen). SP-3 specimens had the best density, hardness, tensile properties and thermal properties compared to other specimens. [ABSTRACT FROM AUTHOR]

Railway transport in the Czech Republic largely uses transit corridors, which are significantly more used than the rest of the railway network. This assumption leads to an increase in the safety of these lines and gradual double-tracking. All these aspects lead to the fact that the given lines are controlled from dispatching centres, while other lines are controlled from regional dispatch offices. The above parameters also apply to other non-corridor but still busy lines. It can therefore be concluded that this trend of remote control brings significant operational and technological advantages. The most visible benefit is the personnel saving of operational employees, but another significant benefit, which is not so obvious at first glance, is the benefit of a more efficient organization and management of railway transport. This impact brings the effect of smoother traffic, which manifests itself in a lower burden on the environment, thanks to fewer train starts and stops, or there will be no complete stop, but only a reduction in train speed. Furthermore, this influence is evident in the more frequent overtaking of trains not in railway stations, but in inter-station sections. All these advantages lead to an increase in an important operational indicator, which is the throughput of the track. [ABSTRACT FROM AUTHOR]

The meeting of the Ottoman Empire with the railway is in the middle of the XIX. century. The railway lines, which were used commercially as a priority area, were used to reflect the military and state power of the II. Abdulhamit. In the First World War, railway lines played an important role in the war, in the transport of military equipment and the army. In the Late Ottoman and Early Republican Periods, the railway, in a sense, became one of the main points of the nation-state building process. The railway, which was used as both military superiority and propaganda in the National Struggle, became the most important area with the establishment of the Republic administration. This study has been prepared in order to reflect for what purposes the railway is used and at what point its functionality is in the nation-state building paradigm. In the study, the foundation of the Ottoman railway policy and its transformation in the Republican Period are included. Starting from the railway policy of the Republican Period, it has been tried to express with examples how important the railway network is in the nation-state building process. In addition, the importance of the railway network in the transfer of the Republican space ideology to other Anatolian cities was mentioned. In this study, the effect of the central cities on the surrounding cities is included in the economy, population and socio-cultural gains gained thanks to the railway. [ABSTRACT FROM AUTHOR]

The African Union and regional economic communities have identified infrastructure development, not least the enhancement of railway systems, as a key priority to advance regional and continental integration policy. The keen interest of Chinese actors in Africa's railway sector is largely welcomed as conducive to increasing infrastructural connectivity within and between Africa's sub‐regions. This article argues that regional railway projects must be assessed against regional political contexts, which crucially co‐determine the degree of coordination and cooperation in the context of region‐centric infrastructure policies. Competing national political agendas, exacerbated mostly by China's bilateral engagement with East African Community member states, has intensified East Africa's infrastructure race. This has resulted in a poorly coordinated standard‐gauge railway project along the East African Northern Corridor; consequently, its economic viability is in doubt.

In response to the industrial world becoming more complex and the recent social distancing caused by the COVID-19 outbreak, emerging technologies such as Virtual Reality (VR) are gaining importance for industrial training. The novelty, however, does not lie in the sole use of VR-based technology but rather in its adaptive and flexible nature. This paper explores the synergy between VR environments and adaptive-based learning and tests the proposed approach in the railway sector. An iterative co-design approach is adopted to develop a VR-based training system for educating train conductors. The developed system is validated with ten conductors, where their learning preference, learning outcome, and learning performance were assessed. The results show an increase in individual motivation and perceived usefulness for the developed VR-based training system, demonstrating a higher learning preference, in comparison to the currently used physical simulator. Similarly, the results outline a knowledge gain in two out of six key knowledge subjects for conductor education and indicate that time improvements per exercise are needed to meet organizational performance goals. Consequently, this research presents an attractive alternative to costly and product-specific physical simulators and offers three strategic managerial implications opening new opportunities for using VR in developing learning training programmes.

The paper is about practice, rather than research, and shows how a complex systems engineering project was done. The project was unique, involving a problem never before investigated, namely, to find the difference in occupational safety of a train driver between being alone in a locomotive cab and having an accompanying assistant. The project used a systems methodology discussed elsewhere. It required understanding the overall New Zealand Rail system and ensuring the objective was clear. A strategy was developed based on a set of system principles. Fault trees gave accident probabilities, from which relative values of Fatal Accident Frequency Rates were computed. As a practical simplification, detailed analysis was confined to a limited part of the overall rail system which could be taken as representative of the whole. Care was taken to treat input information as a whole rather than as separate unconnected items, emphasising information quality, which varied depending on type and source. Major points were the importance of (a) a clear and coherent strategy including careful system decomposition, (b) having a body of information of high and consistent quality, (c) fostering clarity and transparency in communication, and (d) having – and learning – good communication skills. This work is part of a Special Issue on Systems Perspectives: Clarity through Examples (see Dias 2023). [ABSTRACT FROM AUTHOR]

The symmetry between customer expectations and operator goals, on one hand, and the digital transition of the railways, on the other hand, is one of the main factors affecting green transport sustainability. The European Train Control System (ETCS) was created to improve interoperability between different railway signaling systems and increase safety and security. While there are a lot of ETCS Level 2 deployments all over the world, the specifications of ETCS Level 3 are under development. ETCS Level 3 is expected to have a significant impact on automatic train operation, protection, and supervision. In this paper, we present an innovative control system architecture that allows the incorporation of artificial intelligence (AI)/machine learning (ML) applications. The architecture features control function virtualization and programmability. The concept of an intelligent railway controller (IRC) is introduced as being a piece of cloud software responsible for the control and optimization of railway operations. A microservices-based approach to designing the IRC's functionality is presented. The approach was formally verified, and some of its performance metrics were identified. [ABSTRACT FROM AUTHOR]

Food markets were a vital element in the economic life of Britain over many centuries, and the arrival of railways into urban spaces during the nineteenth century provided unprecedented opportunities for them to expand the range and volume of good that they sold. This article examines the impact of railways on these markets during the decades following the arrival of trains into London through a case study of Borough Market. This important London fruit and vegetable market is examined through the prism of its financial records. Detailed analysis of the Market's income produces a timeline for growth, while the records for the goods ported through the Market help to explain the change. The case study also highlights developments in trading techniques at Borough Market that enabled it to prosper during the second half of the nineteenth century, despite limitations placed on its expansion created by the impact of railways on the urban physical environment.

This paper examines the work of a group of Railwaymen Poets, whose verse has been collected as part of the Piston, Pen and Press project. It explores their writings both as part of an emerging theme of accident and loss poetry surrounding the railways in Victorian culture but also more specifically as interrelated texts produced by workers sharing common experiences. Whilst many wrote about all manner of subjects, not just the railway accident, public fascination with accident reporting allowed them to both pursue their literary endeavours and also to use poetry as a form of catharsis. Their poetry, this paper argues, should be read as a collective expression of emotion around the dangerous and loss-ridden nature of their work. [ABSTRACT FROM AUTHOR]

Transportation can be interpreted as the transfer of goods and people from the place of origin to the destination. The transportation process is a movement from the place of origin, where the transportation activity begins, then to the destination and ends at the end of the transportation activity. This research is a normative legal research that uses a conceptual approach. The understanding of the conceptual approach (conceptual approach) is to move from the views, doctrines that develop in legal science. Research related to the implementation of the minimum service standard policy for transportation of people by train on the Yogyakarta-Solo KRL uses secondary data in the form of laws and regulations, news or related cases on social media, previous research, and other supporting data. Based on observations in accordance with the Minimum Service Standards at PM Transportation Station No. 63 of 2019, it was found that there are two aspects, namely the reliability aspect and the convenience aspect that is in accordance between the implementation and the applicable SPM. The categories are quite appropriate on the safety aspect and the comfort aspect. [ABSTRACT FROM AUTHOR]

The Indian Railways is India's biggest employer and undeniably influences the country's transportation network, economy, and social and cultural systems. The network is split into zones for operational reasons. It is vital to evaluate these railway networks to identify their strengths and shortcomings and to improve their performance. Past works often use Data Envelopment Analysis to evaluate railway services. Our contribution lies in the inclusion of several aspects not previously considered, such as (i) both tangible and intangible criteria, (ii) the hierarchical nature of the problem, and (iii) additional useful criteria and data to analyze the performance of the zones, including physical assets, operating ratio, accidents, comfort, travel experience, flexibility, transparency, etc. We use the novel Hierarchical Fuzzy Axiomatic Design method to evaluate the performance of sixteen zones in the Indian Railways since it suits our problem well. We find that the Southern Railway zone performs best, while the Northeast Frontier zone is ranked last. We also identify the strengths and weaknesses of all railway zones. [ABSTRACT FROM AUTHOR]

Due to the interaction of electric multiple units (EMUs), and the electric traction networks, low frequency oscillations (LFOs) appear leading to traction blockade and overall stability related issues. For suppressing LFOs, coronavirus herd immunity optimiser (CHIO), a recently developed meta‐heuristic, has been applied for tuning controller parameters. Controller parameters are tuned to minimise the integral time absolute error (ITAE) that regulates DC‐link capacitor voltage. Results obtained using CHIO are compared with those found using other well‐established algorithms like symbiotic organisms search (SOS) and particle swarm optimisation (PSO). The supremacy of CHIO over other mentioned algorithms for mitigating LFOs was demonstrated for a diverse range of operating conditions. Results demonstrates that overshoot for the proposed algorithm‐based traction unit is 1.0061% whereas those for SOS and PSO based algorithm are obtained as 6.4542 % and 20.6166%, respectively which are quite high. CHIO is more stable than SOS and PSO and requires settling time of 0.1934 s only to reach steady‐state condition, which is 50.21% faster than SOS and 65.03% faster than PSO. Also, the total harmonic distortion (THD) for line currents of the secondary side of traction transformer (TT) are obtained as 0.88%, 2.17%, and 12.48% for CHIO, SOS, and PSO, respectively.

Constructed in the 1850s with heavy British involvement, the Egyptian railway was the first to be built in a non-European Mediterranean territory. Britain – which neither financed nor owned this railway – nonetheless came to view it as a British possession. Originally envisioned as a highway for connecting the Mediterranean to the Red Sea and India, the railway became a means unto itself in Britain's drive for a foothold in Egypt. Taking place in a period of both expanding British influence in the Mediterranean and technological innovation, this article centres on the largely overlooked interconnectivity between the railway and Britain's march to dominance in Egypt. To secure a railway, Britain systematically undermined Ottoman sovereignty in semi-independent Egypt. Britain's efforts ranged from gunboat diplomacy to combating Ottoman legal reform intended to limit capital punishment, which Britain saw as a prerequisite to safeguarding its interests in Egypt. Moreover, Britain de facto supported the railway's construction through mass Egyptian forced labour. Once in operation, the railway became a social site that produced de facto colonial racial hierarchies. Combined, the article shows how, decades before the 1882 British occupation of Egypt, the railway project irrevocably contributed to Britain's gradual colonization of Egypt. [ABSTRACT FROM AUTHOR]

India and China share about 3,488 km long International Boundary, which has three sectors: Western, Middle and Eastern. The Eastern sector comprises two Northeastern states, that is, Arunachal Pradesh measuring 1,124 kms and Sikkim measuring 219 kms, respectively. Due to recent changes in the geopolitical relationship with China, border management and transport infrastructure development have occupied centre stage. In recent years, the Government of India has taken initiatives to develop railway infrastructure in Northeast India. The study will focus on the role of railway transportation in Sino-Indian geopolitical competition. The study is based on secondary data collected from the office of General Manager, Northeast Frontier Railway, the Census of India and reports of Memorandums of Understanding between India and China. The study reveals that railway infrastructure along the border creates geo-psychological pressures on both countries, influencing the divergent geopolitical relationship between India and China. Railway diplomacy is a tool kit of critical geopolitics which reveals the contours of geopolitical competition in borderlands. [ABSTRACT FROM AUTHOR]

Does railway technology represent Japanese national identity? This paper focuses on the narratives indicating railway technology as a form of Japanese national identity representation. Using Japanese government pronouncements and interviews given by people involved in the Japanese railway supply industry appearing in Japanese vernaculars, I show that railway technology constitutes an integral component of the contemporary Japanese identity narrative, which has been built up through a particular technopolitical regime. These narratives consistently refer to the purported safety, reliability, and punctuality of Japanese railways as one manifestation of the high-quality technological skills underpinning Japanese identity construction. However, the narratives also reveal an inherent irony, whereby the confident Japanese Self at once reveals a countervailing, inexperienced Japanese Self, in which the Japanese railway technopolitical regime realizes that its own domestic strength has resulted in a lack of international experience compared to its European, and increasingly Chinese, rivals. I conclude by suggesting that the Japanese railway identity follows a complex construct involving a confident Self in contradistinction to an inexperienced Self both reproduced in opposition to the European and Chinese Other.

The article presents a comprehensive and versatile view of Azerbaijan's transport and logistics system. As a result of the war, after the Karabakh lands were taken back from the thirty-year occupation, Zangezur, the ancient land of Azerbaijan, has also come to the fore to act as a corridor for the railways and highways of the region in the future. Special attention was paid to several points in the study. The first of these is the historical development of the transport and logistics system of the Republic of Azerbaijan. In the article, brief information was given about the status of the relevant system in the Soviet Era. The main focus of the research is the current state of the country's transport system and the development trends in the Nakhchivan region. In this respect, the general and economic information of the independence period and their processing have a special importance. The design, construction and commissioning of the Zangazur Corridor in terms of both railway and highway requirements reflects the long-term development of the subject. The aim of the study is to clarify the current situation, role, and importance at the international level of the transport and logistics system in the Republic of Azerbaijan, and the status of improvements and transformations in this field. The research was carried out by applying grouping, comparative analysis and other related methods on the data obtained from the State Statistics Institute of the Republic of Azerbaijan. The findings obtained as a result of the research, Zangezur Corridor will contribute to the restructuring of the transport logistics system not only in Azerbaijan, but also in the whole region, especially in Iran, Turkey and Russia, and will create an opportunity for the economic and social development of the entire region.

Magnetic field localization is based on the fact that the Earth's magnetic field is distorted in the vicinity of ferromagnetic objects. When ferromagnetic objects are in fixed positions, the distortions are also fixed and, thus, contain location information. In our prior work, we proposed a simultaneous localization and calibration (SLAC) algorithm based on a Rao-Blackwellized particle filter that enables magnetic train localization using only uncalibrated magnetometer measurements. In this paper, a lower-complexity version of the SLAC algorithm is proposed that only estimates a subset of calibration parameters. An evaluation compares the full and reduced SLAC approach to a particle filter in which the magnetometer is pre-calibrated with a fixed set of parameters. The results show a clear advantage for both SLAC approaches and that the SLAC algorithm with a reduced set of calibration parameters achieves the same performance as the one with a full set of parameters.

Central Asian railways are usually discussed in the context of the Belt and Road Initiative, and most studies deal with the main railway line at the heart of this grandiose China-backed project. Turkmenistan represents a somewhat extraordinary example due to the state's massive investments in railways, which have almost doubled the length of the country's rail network in recent decades. The building of the new railways was aimed at linking Turkmen regions together with direct internal connections instead of relying on complicated cross-border passages. It was also intended to make Turkmenistan a transport hub of the Eurasian transport system. Based on the landlocked countries concept and using the analysis of available statistics and transport flows along the two main rail corridors passing through Turkmenistan (east–west and north–south), the paper investigates the gap between these ambitious goals and the actual results, including the reasons for these processes. The emergence of strong competition in the form of other (more efficient) routes has signified a setback for the expansion of Turkmenistan's railway network. [ABSTRACT FROM AUTHOR]

Many communication and signaling systems still rely on cables routed trackside and are thus exposed to induction. The evaluation of induced voltage as touch voltage and as coupled interference is particularly relevant for safety assessment, in terms of electrical and functional safety, and in general for system availability. Induction may be estimated by simplified and conservative closed-form expressions or with more complex simulation models; available models are in general developed for frequency domain. The proposed method provides accurate induced voltage waveform with moderate complexity, as caused by AC traction supply major transients for both 1 × 25 (no autotransformer) and 2 × 25 (with autotransformer) configurations. The method can use simulated or measured frequency responses followed by fitting of a polynomial transfer function H(s) with good approximation (about 3–6%) over an extended frequency interval (up to 1000 Hz). Input to H(s) are the transient waveforms, namely for short circuit and inrush phenomena. For short circuit the proposed calculation method is that of an equivalent circuit including all relevant elements, confronted to standardized method of EN 60909-0 for what regards peak and steady state value and time constant. The H(s) output is the transient induced voltage waveform: comparing the intensity for 1 × 25 and 2 × 25 cases achieves a first validation by comparing to reduction factors documented in the literature. The method is validated using measured inrush current and resulting cable voltage, showing an average error of 2–3%. [ABSTRACT FROM AUTHOR]

The strengthening of the railway mode is one of the main policies that can help to achieve more sustainable future mobility. A methodology is presented to estimate future transport demand scenarios over the medium (2030) and long term (2050) considering three trip lengths: urban, regional, and long distance for two trip purposes: work and leisure. The objective of the scenarios is to answer the question: would railways benefit from a 10% drop in car usage? Qualitative techniques have been applied, based on in-depth interviews and focus groups, as well as a stated preference survey where the people sampled answered to different scenarios which included the presence of a new train, with a high level of service, and other possible new modes of transport such as autonomous cars and buses. The results obtained using Best-Worst discrete choice models show that the rail mode could capture a significant part of the demand from the car over all three journey lengths, but especially for long distance, if the new rail mode were introduced.

Despite the increasing relevance of Open Science (OS) in the European research landscape, very few publications have addressed the analysis of its role within the European rail context. To this effect, the present paper aims at contributing to shed light on the topic by setting the cornerstone for a differentiated analysis of OS in this sector. In order to do so, the analysis is divided into 2 main sections. The 1st provides an overview of initiatives and experiences regarding OS, which have been recently carried out in the sector. The analysis of initiatives and scientific publications has shown that Open Data (OD) is the area attracting more attention and with more potential for expansion mainly due to the commercial interest of the data. As expected, the use of Open Tools (OT) is common but, interestingly, a growing interest in the development of OT in the sector has been detected. The creation of Open Standards (OSt), developed by specific rail stakeholders' groups or by coalitions of different stakeholders is increasing in the last years. Amongst the OS areas analysed, Open Access (OA) and Citizen Science (CS) have shown less progress. However, tendencies toward an increasing interest in these areas within the sector has been also detected. The 2nd section aims to uncover the issues or barriers preventing a wider spread of OS specifically in the rail sector and suggest regulatory avenues and actions to overcome them. The identified issues revolve around 3 topics: the lack of initiative on behalf of the European Union (EU) to a) engage other stakeholders beyond the field of research, and b) leverage untapped OS potential in sector-specific situations, which could contribute to its development; and finally, the absence of a sector-specific OS framework. The establishment of such a framework could have a significant positive impact in OD, which is the most appealing area and thus contributing to the uptake of OS as a whole in the sector. In view of such issues, the present paper suggests the establishment of: (1) a European Rail Open Science Policy Platform in order to create a forum-like space in which to align the stakeholder's positions, and (2) a Joint Rail Data Action Plan to design an OS governance framework, with the aim to ensure the usability, quality, and reliability of data. After identifying the state of OS in the rail sector and the uncovering of several issues that are hindering its development, this paper concludes that the constant further monitoring with regards to needs, challenges and interests (or lack of such) of the different rail stakeholders is key to ensure the continuous development of OS.

The division of Maramures, which took place after the First World War, brought immeasurable damage to the newly formed Romania, leaving Maramures without almost a third of its territory, without vast forests, pastures, mountains, salt mines, factories, railways, but especially without the Romanian villages on the right side of the Tisa River, which for hundreds of years were part of the Sighet Plain and which had hoped for decades to return to the motheland, Romania, expressed on the 1st of December 1918 in Alba Iulia. All the reports and materials drawn up by Găvrilă Iuga during the debates for the conclusion of the peace and border treaties, by the inter-war press, as well as the 1930 report drawn up by the same hardworking Găvrilă Iuga, now prefect of Maramureș, give an image of the disaster, mainly economic, suffered following the surrender of northern Maramureș to Czechoslovakia, the human misery and sadness of the Romanians from the Romanian villages on the right of the Tise, left in another country.

Given the increasing importance of railways in the global context, either as a means of transport or as a tourist product, this paper aims to provide an alternative to the closure of the Aranjuez-Cuenca-Utiel railway in Spain. From the point of view of sustainable tourism, it is intended to highlight the role of this railway as a backbone of territorial socioeconomic development. The recovery and enhancement of the Portuguese Duero line is presented as an example for the future of the Cuenca's Province railway. [ABSTRACT FROM AUTHOR]

Although Lord Plumer’s tenure as high commissioner for Palestine (1925– 28) is sometimes characterized by mainstream Euro-American histories as a period of comparative peace, the year 1927 saw two major disruptions: the Jericho earthquake in July, which caused serious damage to towns and cities including Jerusalem, Nablus, and Lydda; and unrest among Jewish immigrants who found that the local economy had no jobs to offer them— or at least not ones at the European rates of pay to which they were accustomed. This article explores the ways in which each of these crises intersected with Palestine’s infrastructure—in particular its railways, roads, and housing stock. I argue that the disparate ways in which the British administration approached earthquake victims versus the unemployed, the help it offered (or failed to offer), and the policies it implemented are telling about the nature of British governance in Palestine in the mid-1920s and British administrative priorities and concerns. The Mandate authorities’ responses to the quake—characterized by selective negligence—reveal the colonial administration’s weakness, the contested ways in which colonial structures were shaped and operated in the early Mandate period, and the extent to which maintaining a facade before other colonial powers and the League of Nations outweighed substantive action.

Generally, direct shear apparatus is used to determine the shear strength parameters of soil and rock for designing a geotechnical engineering structure. However, the size of the shearing box and the soil sample is key for evaluating the shear strength parameters of test materials, and also testing conditions in the laboratory are different from site conditions. This research aimed to focus experimentally on the effect of particle size and the property of subgrade materials that were necessary keys for installing apparatuses for the direct shear test. According to the experimental results based on a 5 x 5 cm shear box, an increase in average particle size and coefficient of curvature could provide higher shear strength in terms of internal friction angle of the sample, but not for the case of higher value of the uniformity coefficient. Using both 5 x 5 cm and 30 x 30 cm shear boxes, a large B/Dmax ratio is not the key for determining appropriate parameters when testing with samples that have a nearly uniform size. Samples varied in thickness of both the ballast and subgrade layers, were investigated and observed by a large shear box. It was found that good properties of subgrade materials affected the shear strength of ballast materials, and they provided underestimates of strength when the bottom of the shearing box was rigid. The modified parameter of ballast materials on the subgrade layer is suggested for obtaining strength parameters reflecting the ballasted track system. [ABSTRACT FROM AUTHOR]

The opening up of the railway to competition in Europe has been accompanied by many technical challenges never before seen in the railway field. One of these challenges concerns precise energy metering. As European railways have been a monopoly until now, the current systems can only measure the energy consumption of a single operator. In accordance with European law, the installation of an energy meter has been mandatory in new or refurbished rolling stocks since 2014. Nevertheless, these energy meters are still not fully reliable, with misreadings and missing readings being common occurrences. To address the problem of energy metering data reliability, this paper presents a method for validating the reading measurement based on a physical model and validates it in two different case studies. For the issue of energy metering data availability, different estimators are developed, and their performance are shown with the aim of calculating the missing consumptions for both case studies. Finally, the paper suggests how these methods may be implemented in other types of trains. [ABSTRACT FROM AUTHOR]

In late 2014, disputes around land, displacement and compensation related to the roll-out of big infrastructure projects across Ethiopia mutated into much deeper conflicts about the authoritarian nature of the state, the political marginalization of particular ethnic groups and the legitimacy of the Ethiopian People's Revolutionary Democratic Front (EPRDF). As security forces continued to quell mounting protests, the federal government imposed a state of emergency. This article explores how the EPRDF navigated this period of political fragility and why infrastructures were used as strategic vehicles for the party's discourse. Drawing on the Addis-Djibouti Railway as an analytical lens, this research explores how the party strategically deployed posters, images and speeches centred around infrastructure to directly respond to protestors' grievances. This choice to deliberately embed visuals and rhetoric descriptions of such megaprojects in its political messaging about Ethiopia's aspired 'unity in diversity', 'democracy', and 'good governance' illustrates how infrastructures were effective carriers of the party's narratives. Roads, railways, and dams rendered EPRDF's abstract ideas of political reform and economic renaissance tangible. At this critical juncture, these tangible discourses not only expose how the party attempted to restructure state-society relations in Ethiopia, but also how centrally anchored infrastructure was in the EPRDF's self-styled developmental state project.

Background and purpose: Metabolic syndrome reduces the quality of life and cognitive function. The health of railway staff is of great importance as proper health status could increase the quality of rail services delivered. Therefore, this study was performed to assess the quality of life of railway employees according to being affected by metabolic syndrome or not. Materials and methods: This cross-sectional study was performed in 409 employees of the railway services attending an occupational health clinic for annual examination in Mashhad, Iran. Demographic characteristics were recorded and body mass index, blood pressure, and waist circumference were measured. The levels of FBS, HDL, LDL, and triglycerides were also evaluated. Metabolic syndrome was defined according to NCEP ATP III criteria. Finally, the quality of life score was compared between people with/without metabolic syndrome based on the WHOQOL-BREF questionnaire. Results: The mean age of participants was 38.65 ± 6.4 years. Work experience and BMI were significantly higher in staff with metabolic syndrome (P= 0.0005 and P< 0.001, respectively). The mean scores for physical health (11.36±1.47) and social relations were found to be significantly higher in participants without metabolic syndrome (P<0.001 and P= 0.001, respectively). The mean score for mental health in people with metabolic syndrome was significantly higher than the other group (P= 0.02). The mean score for environmental health did not show any significant differences between the two groups (P= 0.31). Conclusion: Metabolic syndrome can affect the quality of life of employees, including their physical, mental and social health. [ABSTRACT FROM AUTHOR]

Rail transport is one of the basic pillars of the national economy, as it is the only means among the various means of transport capable of bearing the greatest burden of transport obligations, both for goods and passengers between all regions, at the lowest costs. The research deals with a study of the status of railways and their role in the development of Basra Governorate for the period (8181-8102) based on the method of objective analysis of official data and converting them into tables and graphic forms.

Shift2Rail is a joint undertaking funded by the EU via its Horizon 2020 program and by main railway stakeholders. Several Shift2Rail projects aim to investigate the application of formal methods to new ERTMS/ETCS railway signalling systems that promise to move European railway forward by guaranteeing high capacity, low cost and improved reliability. We explore the ERTMS/ETCS level 3 full moving block specifications stemming from different Shift2Rail projects using Uppaal and statistical model checking. The results range from novel rigorously formalised requirements to an operational model formally verified against scenarios with multiple trains on a single railway line. From the gained experience, we have distilled future research goals to improve the formal specification and verification of real-time systems, and we discuss some barriers concerning a possible uptake of formal methods and tools in the railway industry.
