Two contracts for the installation, testing and commissioning of signalling services and related civils and power works on the Hammersmith & City, Circle and Metropolitan Lines have been awarded to VolkerRail by London Underground.
London Underground is introducing new S8 rolling stock onto the Hammersmith & City, Circle and Metropolitan Lines in early 2011.
These trains are 23 metres longer than existing rolling stock and therefore in order to operate on the London Underground network, alterations are required to the existing signalling infrastructure.
Lillie Bridge Depot and Triangle Sidings
The Lillie Bridge Depot and Triangle Sidings are located to the South West of London near Earls Court. VolkerRail has been selected to provide design, installation, testing and commissioning services for signalling and related civils and power works.
Work on the project commenced on 2nd July 2010, with scheduled completion dates of November 2010 for Lillie Bridge and April 2011 for Triangle Sidings.
In order for the new rolling stock to operate, platform extensions are required at Ladbroke Grove Station resulting in a requirement to relocate existing signalling infrastructure to make way for lengthened platforms.
The work comprises of signalling alterations to allow for the berthing of longer rolling stock; including installation of location cabinet's trackside to allow decommissioning of the existing relay room and replacement of life expired lead signalling cable.
VolkerRail will provide installation, testing and commissioning services for signalling and related power works. The project commenced on 25th June 2010 and is due for completion in November 2010.
