Metropolitan Line Extension Programme - Concept Design

Disciplines: Cable Route Design, Systems Engineering

SRC Infrastructure developed a cable route concept design for the Metropolitan Line Extension Programme. The project was an unusual challenge as there was no existing railway running for a significant part of the route. SRC Infrastructure’s team had to derive requirements from an existing power study, from indicative layout drawings and our own understanding of what the ATC solution for this area might be. ​ The scope of the commission included requirements definition, standards analysis, risk analysis and production of CDS and approval of Form A submissions. The Concept Design CRMS had to carry 11kV, Pilot, radiating cable, miscellaneous LU, and LU signalling, communications and power cables.

Key achievements:

  • The SRC Infrastructure team liaised with all engineering stakeholders (LU and NR) to achieve consensus and approval

  • Leveraging our expertise of the probable signalling system to add a very significant level of knowledge to the Client team and produce a submission which far exceeded expectations
