Deep Tube Upgrade CRMS Feasibility

Disciplines: Mechanical, Electrical, Signalling Engineering

SRC Infrastructure was commissioned to review the feasibility of potential cable route management solutions between locations for TfL’s Deep Tube Upgrade Programme (The key project objective was to identify the most cost effective models. ​ 5 stations were reviewed Cockfosters Station, Oakwood Station, Southgate Station, Arnos Grove Station, Bounds Green Station

Key recommendations:

  • Tunnel sections and Stations are crowded with existing system therefore Cable tunnel chambers could provide possibility of new CRMS installation.

  • A concomitant Anchor post system may alleviate confined space issues in many cases.

  • TT wires and redundant cables need to be removed to free space for new CRMS Impact of this work needs to be discussed and planned in detail.


Key considerations:

  • Costs and Schedule

  • Maintainability

  • Operational Impact

  • Buildability and Logistics

  • Interface with existing infrastructure

  • Heritage and 3rd Party stakeholders
