Just delivered from Metropolitan-Cammell, new-built London Transport battery-electric locomotive No.L16 stands outside the car sheds at West Ruislip Depot on 27th June 1970. Crimson lake livery was applied to battery locos from the early 1960s using supplies of LT steam locomotive paint. This was changed to yellow in the early 1980s, which was deemed to be more safety conscious. The locomotives can draw power from the 630 V electrified rails like a normal tube train, or run on 320 V DC traction batteries when the power is switched off. The body sides take the form of louvres to allow ventilation around the batteries and all body panels are hinged to allow the batteries to be removed. Five locomotives (L16-L19) were in this order and they were employed on the new Jubilee Line construction trains. ©Gordon Edgar/Railphotoprints.co.uk
