The annual conference is the most important event of the German Mechanical Engineering Society (DMG) in the course of a year. The theme of this yearly conference was "Mobility and Logistics 2030 - How do we make use of the system advantages of rail". In the lecture event, various experts from the rail transport sector dealt with the conference topic from the point of view of transport policy, science, industry and the railways DB and SBB. A subsequent panel discussion deepened the topic. In addition, the Beuth Innovation Prize was awarded to the young traffic engineer Fabian Wirth for his work with the topic "The future of rail freight transport in Germany". On the occasion of the official reception the first evening, Dipl.-Ing. Peter Lankes was awarded the Beuth Medal of Honour far his great achievements of the further development of high-speed rail transport in Germany. [ABSTRACT FROM AUTHOR]

Based on the two described approaches in the first part of the article, the applicability of various approaches is discussed for urban rail-bound networks in Part 2. The quality of operational service will be reduced due to the road traffic influences. Extra waiting time of urban rail-bound transport is resulted during operation. The calculation of the average waiting time based on the model approaches allow a quantitative determination of the significant road traffic influences on the urban rail-bound transport.

In urban rail-bound systems, operation of trains is influenced not only by the disturbances in the rail-bound system itself, but also by other modes of transport like road traffic in various urban mixed traffic zones. In this paper, two simulation-based approaches for modeling road traffic influences on urban railbound transport, modeling approach and distribution approach, are presented as a resulting integrated model including influences of road traffic and calibration of disturbances based on a suitable probability distribution with significant disturbance parameters respectively. The explanation of the approaches in the first part of the article is followed by aspects of applicability in the second part. [ABSTRACT FROM AUTHOR]

A deadlock is a situation in which a number of trains cannot continue their path at all because every train is blocked by another one. In real railway operations, deadlocks are avoided by the timetable. In case of delays, dispatchers are in charge of avoiding deadlocks by appropriate decisions. For synchronous railway operations simulations, an adequate solution against deadlocks has not yet been found. As part of a BMWi funded research project of Deutsche Bahn, a new approach for deadlock avoiding in synchronous railway operations simulations was developed and tested in case studies.

Schäden auf Gleisoberflächen wie Riffel, Schlupfwellen und Rissbildungen bedrohen die Funktionsfähigkeit von Gleisen im kommunalen Schienennahverkehr. Zudem verstärken Riffel und Schlupfwellen verkehrsbedingte Schallemissionen, was den Lärmschutzbestrebungen vieler Kommunen zuwiderläuft. High Speed Grinding-city adressiert beide Herausforderungen: Die speziell optimierte Kompaktvariante des praxiserprobten Hochgeschwindigkeits-Schleifverfahrens von Vossloh kommt dank hoher Arbeitsgeschwindigkeiten ohne Streckensperrungen aus. Regelmäßig eingesetzt, bekämpft der schonende HSG-Schienenschliff Verschleißerscheinungen bereits im Ansatz und verlängert so die Schienenliegedauer. Zudem empfiehlt sich präventives Schienenschleifen als effektive und kostengünstige Lärmschutzmaßnahme. Damage to rail surfaces, such as corrugation, slip waves and cracking jeopardize the serviceability of rails in municipal rail transport. In addition, corrugation and slip waves increase traffic-related noise emissions, and this counteracts the noise mitigation efforts of many municipalities. High Speed Grinding-city addresses both challenges. The specially optimized compact variant of the tried-and-tested high-speed grinding process from Vossloh manages without line shutdowns thanks to its high working speed. Regularly applied, gentle HSG combats the symptoms of wear at source and thus extends rail service life. In addition, preventive rail grinding is recommended as an effective and inexpensive noise mitigation measure. [ABSTRACT FROM AUTHOR]

TRANSITECTS (Transalpine Transport Architects) is an European project aiming at developing and implementing attractive rail products and systems to disburden traffic bottlenecks in the Alps and to mitigate related negative effects of traffic. For the shift of traffic from road to rail TRANSITECTS creates sustainable intermodal solutions to fit changing markets - especially combined transport products for transalpine freight traffic. Furthermore, the project supports the development of intermodal nodes and proactively fosters the railway system through intensive networking. TRANSITECTS has started in July 2009 and is funded by the Alpine Space Programme of the European Regional Development Fund (ERDF) and national cofinancing. 16 partners of four countries (Austria, Germany, Italy, and Slovenia) are collaborating in a transnational network. During the three-year runtime, numerous measures have been developed: Traffic studies have been elaborated, concepts for additional rail services developed and strategies for the improvement of intermodal nodes worked out. The paper explains the project, its aims and approaches and highlights some relevant results. [ABSTRACT FROM AUTHOR]

The proven TWINDEXX Vario double-deck trains from Bombardier Transportation have continuously been adapted to the new requirements of modern rail passenger traffic. Thereby a variable product platform was developed. With the appropriate equipment, the trains will be used in the future for long-distance traffic of Deutsche Bahn. Comfortable seats, more legroom, luggage racks close to the seats or particular quiescent zones are only some examples of the special passenger comfort found on these trains. The new flexible traction equipment in the motorized cab cars enable the TWINDEXX Vario double-deck trains to operate in both regional and longdistance traffic. Operation as pure electrical multiple unit or as classic push-pull train with electric or diesel locomotive, as well as the coaches being compatible with previous vehicle generations, open more fields of application.

Germany can look back on two decades of high-speed traffic,at 250 km/h and more. Over this period not only train technology has made tremendous progress. Railway reform on a national level and Europe-wide liberalization of rail transportation have led to major changes, aimed at keeping the railways competitive in changing market circumstances. This is bearing fruit in many respects. The demands that politicians, manufacturers and customers make of each other are however constantly growing and there is still plenty of need for further development of the system railway. Ever since its earliest days - and starting again with the high speed era - rail traffic has been a success story. Siemens plays a significant role here and will remain an innovative driving force in the future too. [ABSTRACT FROM AUTHOR]
