Plans for two depots for the maintenance of the new Thameslink fleet have been published in advance of the contract being awarded.
Two sites, at Three Bridges station in south London and Hornsey depot in north London, have been chosen as depot locations.
Bids to build and maintain the depots alongside the new fleet of longer 12-carriage trains were submitted by Alstom, Bombardier Transportation and Siemens on June 25, and are being evaluated.
The new trains – a key element of the Thameslink programme – will require depots with modern maintenance facilities and railway sidings that are long enough to accommodate them.
Plans at an early stage
The newly published plans detail the site selection criteria, how the depots will be built and the key design considerations.
The plans also outline the potential environmental effects of the depots, and the mitigation measures that will be taken to prevent them.
The documents state: “Plans to build the two depots are still at an early stage but they are needed by 2012 to help keep the new trains running.”
ARUP was responsible for the site selection process and was employed by the DfT to carry out the initial design and options report for the depots.
Network Rail, the Department for Transport (DfT) and First Capital Connect are also behind the depot plans.
The construction time for the depots and the associated facilities is estimated at 18 months. Local councillors have been briefed on the depots, and public exhibitions have been held for local residents.
