London to Corby | UK
The project was part of Network Rail’s Midland Main line electrification programme and involved re-signalling between Bedford and Kettering. The goal is the reduction of industry costs and environmental benefits through lighter rolling stock, reduced fuel costs and lower carbon emissions. Among others, the project included replacing existing Westpac and route relay interlockings with the Trackguard Westlock System as well as renewing the signalling equipment using the Trackguard Westrace Trackside System and Frauscher axle counters.
To replace the existing route relay interlocking with the Trackguard Westlock System, the Frauscher Advanced Counter FAdC with RSR123 was implemented as the track vacancy detection system. To establish an interface with the Trackguard Westlock System, the track sections are output via the WNC failsafe ethernet protocol. The London to Corby project was set up with an A and a B Network. This guaranteed network redundancy for enhanced availability.
Since the RSR123 and the Frauscher Advanced Counter FAdC do not require any trackside electronics, tail cables were connected to the signalling cable using Glenair plug couplers. Due to this, the amount of equipment trackside could be highly reduced. Trackside connection boxes were installed as installation and maintainer preference as well as plug couplers (i.e. head to Glenair plug coupler, coupler to dis box, dis-box to loc).
The RSR123 also complies with high standards in reliability and robustness which were required by the Network Rail Infrastructure.
