New building for Class 700 maintenance
Govia Thameslink Railway and Siemens have marked the completion of the construction of a new maintenance building at Hornsey depot.
The building forms part of an overall enlargement at the site and will be used to maintain the Class 700 and 717 Siemens-built trains for Thameslink and Great Northern suburban services respectively. Construction of the new building, along with new sidings and improved servicing facilities, was carried out by Volker Fitzpatrick on behalf of Siemens.
The original buildings at Hornsey are used to maintain six fleets for GTR, including the Class 387 EMUs the operator is introducing on its Great Northern route. Siemens will maintain the Class 700s (which will be based jointly at Hornsey and Three Bridges) and Class 717s in the new building. GTR and Siemens say the site will also become a centre of excellence for apprenticeship schemes run by both GTR and Siemens, with up to 20 apprentices to be trained there each year.
The completion of the new maintenance building means the site is now one of the UK’s largest train servicing facilities at over 72,500 square metres. The Class 700s will start working on Great Northern routes in 2017, before beginning cross-London operations through the Thameslink core in May 2018, with the Class 717s introduced in 2018.
New facilities provided as part of the work include an underframe cleaning facility, two carriage wash machines, two bogie drops and full powered signalling to replace hand signalling. This follows upgrades including provision of a new control room and signal control depot on the original site.
