In recent years, there has been a continuous and rapid increase in the number of urban mass railway transportation systems put in revenue service worldwide. As new metro, tramway, and monorail systems are being put into circulation, they are supplemented by innovations in rolling stock, infrastructure, and operational equipment / procedures. As a result, they provide more efficient public transport to more people. Consequently, the need arises for frequent updates of relevant data. This paper initially attempts to systematically record the tramways, the metros, and the monorails currently in revenue service and under construction worldwide. It continues with a statistical analysis of their basic characteristics in an effort to showcase and compare trends. For meaningful information to be acquired, data acquisition is based on clear definitions of such systems. In this aspect, the paper provides clear criteria for the distinction of urban mass railway systems. The findings were recorded at the end of 2019. [ABSTRACT FROM AUTHOR]

In this paper, a specific procedure is adopted for making a distinction between conventional-speed rail, high-speed rail, and very high-speed rail. The criteria adopted correspond to the needs of the actors that manage the 3 constituents of a railway system and namely the infrastructure managers (track) and the operators (rolling stock, railway services). Based on this distinction, research was focused on: a) identifying all countries, which possess at least one track of very high-speed b) making a record, for all the identified countries, of the total length of tracks that are characterized as very highspeed tracks c) analyzing the evolution of the construction of very highspeed tracks over the years d) making a record of very high-speed trains that were set in circulation over the last 5 years Making a record per country, of the longest direct route, which, based on the adopted definition, provides services of very high-speed.
