3 Driving Motor (DM) cars of D78 Stock stand at the west end of Ealing Common Depot; (from left to right) 7526, 7032 and 7018. 7032-7007 were used on 7 May 2017 for the D Stock "Farewell" tour (photograph taken just after Train 755 had been stabled).
Ealing Common Depot is a London Underground railway depot on the District line, located between Acton Town and Ealing Common stations. It is accessed by road on Granville Gardens, off the Uxbridge Road in Ealing Common. From the main-line (District) it is accessed at Ealing Common by a junction immediately to the east of the platforms. Trains can enter or leave the depot to/from either the Westbound or Eastbound tracks at Ealing Common. It is also accessed at the Acton Town end through a junction just to the West of Acton Town eastbound platforms. Trains can enter or leave the depot to/from either the local or fast eastbound platforms, however trains in either of the westbound platforms at Acton Town have no access to/from the depot.
Piccadilly line trains were stabled here until 1964. At the same time, the District line ceased stabling at Northfields. On the eastern side of the depot, access is only possible by foot, not road vehicle. However there is a separate yard to the north-east corner of the depot which is not used for normal day-to-day operations. This yard is now the yard of the London Transport Museum Depot, It is still linked into depot by rail, however access is through a locked gate, for both rail vehicles and people. This yard is accessible by road, via a service road (known as Museum Way) off Gunnersbury Lane. This yard is where the D Stock trains were transferred to, via Ealing Common Depot. This is where they were then loaded onto low-loader trucks to be taken away for refurbishment. The trains were also returned to LUL this way.
