Hainault:
4 car unit of 1962 stock
3 car unit of 1972 mark 1 stock
Both owned by Cravens Heritage Trains and unlikely to move under their own steam again (particularly the '72).
During sandite season, the 8-car east-end Central line sandite train (1962 stock) is based here.
Ruislip:
Ex-Met Railway electric loco No. 12 Sarah Siddons
5-car west-end Central line sandite train/pilot unit (1962 stock).
3 car unit of 1960 stock owned by Cravens Heritage Trains, unlikely to see use on the Underground again following its ill-fated return journey from the Epping Ongar Railway last year.
The Track Recording Vehicle, formed of converted 1973 stock track recording car and two 1960 stock pilot cars is maintained here.
Neasden:
4 car unit of A60 stock (currently made up to 5 cars with the addition of sandite trailer), for sandite duties in the autumn.
4 car unit of A62 stock, backup for sandite duties if the A60 is unavailable.
Acton Works:
4 car unit of A60 stock, source of spares for the two units at Neasden.
4 car unit of 1938 stock owned by the museum, currently being worked on.
Some or all of the Q Stock cars also owned by the museum, not sure what's happening with these at the moment.
Various other bits and pieces, not necessarily complete units, comprising 1962, 1967 and 1972 mark 1 cars, some with a future and some not.
Aldwych:
4 car unit of 1972 mark 1 stock, used for filming and fire brigade exercises.
Morden:
Stuffed and mounted single car of 1959 stock.
Can't think of anything else!
