Case Study – Network Rail, London Bridge

Network Rail London Bridge

HICSE were invited to put forward proposals using TREsim to provide a realistic simulation of the proposed revised control for the London Bridge Area to enable Network Rail to de-risk the new Thameslink signalling project for the area.

Network Rail required investigating the replacement of nine signalling positions at the London Bridge Area Signalling Centre with new control and interlocking from three Signallers workstations. In addition, Network Rail wishes to introduce Automatic Route Setting (ARS) and new Train Describer system for the area.

HICSE provided simulations to give a faithful representation covering the three proposed workstations for amended line-of-route control. HICSE designed the simulation using a fully working TREsim simulator on which it is possible to consider how the signallers will work under manual failure condition running a future system timetable on London Bridge.

The objectives were to provide:

  • Further proof of line of route concept
  • Validate the choice of signalling area divisions
  • Allow the fine-tuning of the signalling areas
  • Allow methods of dealing with train and infrastructure failure to be investigated
  • Provide the basis for a future training system for London Bridge

The simulators have been designed such that all three workstations can work independently or simultaneously, the latter enabling the interaction between signal operators to be assessed.
The train movements and operational characteristics are based on stock currently working in the Thameslink Area as well as the proposed Thameslink Rolling Stock, currently under procurement ultimately simulating the Thameslink 2018 timetable, operation at 24 trains per hour.
