Rail Panel: High-Speed Trains Worldwide - Opportunities and Limitations
Wednesday 23 May 2019, 14:00 - 15:40
Chair: Dr. Stefan Dörsch, DB Systemtechnik GmbH
Chair: Mr. Roberto Tione, WABTEC-Faiveley
This panel brings together leading rail transport experts from both Europe and Asia to discuss future research directions and challenges facing the rail sector. Each panellist will make a short presentation on the status of the high-speed traffic in their domain and to reflect on the latest topics in braking of high-speed rail vehicles. Special focus is given to braking and safety concepts of high-speed rail vehicles.
Travelling time is one of the most important influences on the decision regarding which means of transport a customer will use. If the travelling time between major cities exceeds 3-4 hours, a means of transport other than the railway will be chosen.
To allow travel within these time frames, high-speed rail travel will need to become commonplace and speeds of 250 km/h to 380 km/h can be expected, depending on the country. Not only the trains themselves, but the whole railway system including the signalling and track system must be compatible with these velocities. On the other hand, costs for maintenance and energy consumption are strongly and exponentially dependent on the train velocity. Finding the cost optimal working point in this target conflict is strongly dependent on the concrete situation in each country.
Which solutions did a country choose to match their situation?
What future challenges are there in the high-speed sector (to both industry and operators) and how are these challenges being addressed?
Did we settle for 380 km/h for regular commercial operations, even in countries where topography and/or travel distances would allow or require higher speeds, due to technical and commercial influences?
Following the short presentations by the panellists, there will be general discussion chaired by Roberto Tione, Wabtec-Faiveley, and Dr. Stefan Dörsch, DB Systemtechnik GmbH, where delegates will have the opportunity to give their views on the future challenges and raise their questions with the distinguished panellists.
