The District Line platforms at Earl's Court London Underground station. The left hand train is an unrefurbished D78 stock, while the train on the right of the picture is one of the first few D78 units to have been refurbished. The train in the centre is most likely a C69 stock on a service to Edgware road.
The Picadilly line also serves this station, but calls at tube-level platforms beneath the sub-surface ones seen here.
