In March 2017, the Czech parliament passed a resolution obliging the government to launch a high-speed line program. Government resolution on launching the program was adopted in May 2017. The High Speed Railway Development Program in Czech Republic is intended to target international connections in several axes: Dresden-Prague-Brno-Vienna/Bratislava/Budapest, Katowice-Ostrava-Brno- Vienna/Bratislava/Budapest, Wroclaw-Prague-Munich. This network is supposed to improve Prague's accessibility to other cities in Czech Republic but also to major agglomerations of neighbouring states. This project is not only railway project but also a project of national development. One-day trip will include, among others, Dresden, Berlin, Vienna, Bratislava, Budapest and Warsaw together with other big cities in Poland. Since 2010 in Polish - Czech cooperation are being prepared studies on lines Wrocław - Praga and Katowice - Ostrava. The high-speed railway program implementation in Czech Republic and in Poland and Baltic Countries will result in an effective connection between Prague and Baltic Countries capitals. Creation of an international fast railway network in Central Europe is a part of the EU's transport policy framework for TEN-T network development and will contribute to the progress of economic links in the region. In addition, it is going to be involved in the European Union social and economic cohesion improvement.

Railway Operation

The optimization problems of train timetabling and platforming are two crucial problems in high-speed railway operation; these problems are typically considered sequentially and independently. With the construction of high-speed railways, an increasing number of interactions between trains on multiple lines have led to resource assignment difficulties at hub stations. To coordinate station resources for multiline train timetables, this study fully considered the resources of track segments, station throat areas, and platforms to design a three-part space-time (TPST) framework from a mesoscopic perspective to generate a train timetable and station track assignment simultaneously. A 0-1 integer programming model is proposed, whose objective is to minimize the total weighted train running costs. The construction of a set of incompatible vertexes and links facilitates the expression of difficult constraints. Finally, example results verify the validity and practicability of our proposed method, which can generate conflict-free train timetables with a station track allocation plan for multiple railway lines at the same time.

Abstract: China’s high-speed railway network has already achieved speeds of 350 km/h; however, this could be further increased to 400 km/h. After considering the development status and technical level of the high-speed railway system in China, this study indicates that there are four key technologies involved in improving its operational speed: the track, the electrical moving unit, the control system and the traction power supply. Through an experimental analysis, an evaluation index for the high-speed railway is then constructed based on four aspects: safety, comfort, intelligence and environmental protection. Using this system, the rationality of the high-speed railway speed-improvement plan can be scientifically evaluated. The results are of practical significance to the Chinese railway administration, as they can be used to formulate specific plans to increase rail speeds, and therefore promote the rapid development of the high-speed railway network in China.
