Crossrail Train Maintenance Depots

The £15bn Crossrail project will connect Heathrow Airport to Essex via 26 miles of new tunnels directly under the City to ease pressure on London's Underground system and cope with the city's projected population growth. As part of this, the trains for the new ‘Elizabeth line’ service (built by Bombardier Transportation) required a new maintenance depot for overnight stabling and periodic maintenance.

RPS initially provided specialist design support to Bombardier for their successful bid to deliver rolling stock and an associated new maintenance depot at Old Oak Common. Upon award of the rolling stock contract RPS was appointed by Bombardier’s construction delivery partner to provide detailed design services for the new depot’s Operational, Maintenance & Control Building.

The depot will be the main maintenance hub for the servicing of the 65 new trains and will provide 9 “roads” within the maintenance building, supported by a further 30 stabling roads. The state of the art maintenance facilities will also include a wheel lathe, equipment drop, train wash, heavy lifting facility, driver/train crew accommodation and a driver training suite with train simulators.

The Operational, Maintenance & Control Building was designed using a coordinated Building Information Modelling approach and incorporated sustainable solutions including thermal solar and photo voltaic panels, a Combined Heat & Power plant and thermal piles to provide winter heating and summer cooling.

In addition to the Old Oak Common Depot, RPS has provided design support to Volker Fitzpatrick and Crossrail in the redevelopment of the existing train maintenance depot at Ilford. New stabling sidings and operational/cleaning staff facilities have been created for the servicing of Elizabeth line trains, following the construction of replacement logistics/storage facilities and paintshop, and the major reconfiguration of an existing heavy maintenance building.
