Railway Infrastructure - Part 2 (Power Distribution & Signalling)

Rail traffic is the most important form of public traffic in Europe, as the density of the railway network is very high compared to the other parts of the globe. An efficient utilisation of the railway infrastructure is an essential component of a high-quality transportation system. Designing and using the rail infrastructure is the major challenge for the railway sector.

To address this issue, this module will concentrate on railway traction power and signalling systems used to control the railway traffic in an effective way. It will include the alternative and direct current power systems applied in the railway industry. Some main fundamental aspects and challenges of the railway power feeding, overhead line inductance, ground current effects, signalling control systems, and quality regulations will also be described. The railway power substation and protection components will be introduced, and their reliability will be discussed in the later part of the module.
