Project Signals and Power Civils
civils and signals power portfolio
Under our London Underground framework we have undertaken a large and varied portfolio of works in support of CPD Signals (Tfl) upgrades. Civils and trade support, plant and materials have been supplied over a number of sites and projects over the past 3 years.
Each of the sites required bespoke solution to install bases, CMS and metal structures, a selection of these are showcased here.

Fog Repeaters
The works involved the installation of 73 anchors & posts along the Metropolitan & District (Piccadilly) lines, some of the works bordered on the Network Rail lines. We had to survey the areas in conjunction with TfL to determine suitable location and provide feedback to be incorporated into the installation including Clearance Approval Forms (CAF’s), CDF Logs and identify locations where an anchor would not be suitable e.g. over culverts. It was important to liaise with TfL to ensure the existing signals on the existing post and the new signals being installed on the new post did not significantly impact on the clearance from the track.
Hammersmith Depot
As part of the 4LM upgrade the M63 points machines are being change along the lines with new Surelock points machines this includes the new signals and operational components e.g. cable termination boxers, power boxes, manual points control boxes, point heater TJB’s, kiosks, etc.
It was Spoor-Tech’s role to install all the concrete bastes, percussion driven anchors, walkways and posts to facilitate the installation including a CRMS around the existing depot shed.

Lillie Bridge Depot
As part of the 4LM upgrade the M63 points machines are being change along the lines with new Surelock points machines this includes the new signals and operational components e.g. cable termination boxers, power boxes, manual points control boxes, point heater TJB’s, kiosks, etc.
It was Spoor-Tech’s role to install all the concrete bastes, percussion driven anchors, walkways and posts to facilitate the installation including.
The scope was similar to Hammersmith Depot.
Cromwell Curve
As part of TfL’s upgrades in conjunction with 4LM the Rail Gap Indicators (RGI’s) on the Cromwell Curve were all moved and/or replaced. All the RGIs were installed on concrete bases or on bracketry fixed to tunnel walls or existing posts in accordance with the Cutting, Drilling or Fixing Log (CDF Log).
Sighting, positioning and fixing arrangement were adjusted on site as the installation progressed or obstructions were encountered.
Barking CRMS
As part of the 4LM signals upgrade new SER buildings were constructed along the upgraded lines including the District Line out of Barking, our task was to provide a CRMS trackside to allow an existing cable run along the bottom of the embankment to be removed to allow access to the SER site.
The CRMS had to have sufficient capacity for HV, LV, Signal and comms with suitable segregation and installed at a height which facilitates maintenance. Added to the difficulties was the existence of an existing CRMS track side at the top of the embankment.
We suggested the used of a concomitant anchor post (Anchor Systems) which could be installed through the existing CRMS adding the new capacity directly over the existing CRMS.
