London Overground Capacity Improvement Programme (LOCIP) ? Silwood Sidings


Cleshsar Contract Services Limited, Heather Park House, North Circular Road, Stonebridge, London NW10 7NN

Project Details

Design, specification and preparation of assurance documentation for site distribution services, including electrical distribution, site and walkway lighting, water distribution (including fire main) and specialist earthing systems.

The London Overground Capacity Improvement Programme (LOCIP) increased capacity on the London Overground network with 4 Car Trains converting to 5 Car configurations. This required the provision of new stabling facilities at Silwood Sidings to provide housing for trains relocated from New Cross Gate Depot due to the additional length.

Design services included new lighting schemes for walkways, driver ?hop-ups? and roadways, site electrical distribution including signalling power supplies and specialist earthing systems, and a delivery system for de-icing fluid to be pumped from a central bowser to distribution points adjacent the stabled trains.
