Class 73 'Electro-Diesel' Profile and Models

Class 73 'Electro-Diesel'

73122 at Bournemouth in October 1987. ©Phil Richards

The Class 73s are highly unusual electro-diesel locomotives built between 1962 and 1967, that can operate either from an on-board 600hp diesel engine or from 650/ 750V DC third-rail. Until the introduction of the Class 88, the 73s were unique in their electro-diesel functionality following the withdrawal of the Class 74. They produce significantly more power when on third-rail, so rarely leave the Southern regions - however, some are currently used on the Caledonian Sleeper service in Scotland. Later in life, some were converted to the 73/9 subclass which provided them with the AAR system for multiple working as well as new engines. Many are still in service to this day, whilst eight have been preserved.
