Rail Systems - Crossrail Learning Legacy

Rail Systems comprise the many electrical, electronic and other systems necessary for trains to run, they include permanent way (track), traction power (the electricity supply to the train), signalling, communications and several others. Each of these needs to be designed and installed so that they work together safely and effectively. This topic area includes papers and good practice documents on how these systems were designed, installed, tested and commissioned.

Validation of the Tunnel Pressure Signature of the Crossrail Class 345 Train Topic area: Rail systems When a train enters a tunnel, it creates a pressure pulse which is experienced by passengers on the train and which propagates along the tunnel. The pressure pulse results in loads being generated on items of infrastructure, such as platform screen doors and tunnel ventilation equipment. The tunnel pressure signature i...	31/08/2016	Technical Paper
