Old Oak Common Depot-London

The remaining Great Western Railway buildings adjacent to the canal are today part of EWS and are currently operated by their commercial subsidiary Axiom Rail. Since the introduction of the InterCity 125 trains in the 1970s this site has maintained freight locomotives and more recently carriages for charter trains. The site includes the Lift Shop, the Pullman Car Shed (where the Blue Pullman trains were once maintained) and the former heavy repair building known as 'The Factory'. This site together with the adjacent Coronation Carriage Siding have been schedulled for compulsory purchase for the Crossrail project in 2009. EWS are co-operating and will be vacating the site in the Autumn of 2008 and spring of 2009. All the remaining Great Western Railway buildings are to be demolished.

Adjacent to the Great Western Main Line is the second part of Old Oak Common TMD, the High Speed Train depot. Here trains which operate the First Great Western services, the Heathrow Express and Heathrow Connect are maintained.

South of the line is North Pole depot, where the Eurostar trains which operate on Channel Tunnel routes used to have their UK base. With the opening of the new international terminal at St Pancras railway station, all servicing was moved to the new Temple Mills depot located near Stratford International. The North Pole depot is approximately half a mile south-west of Willesden TMD.
