60 Years of AC Electrics

Standard

60 years ago on the 27th Nov
ember 1959, Britain’s pioneer 25Kv A.C. electric locomotive was officially handed over to British Railways. Then numbered E3001, it 
was to be the first of a long series of successful 
locomotive designs for the West Coast Main
Line (WCML). Within this series there have
 come to be seven basic designs, and a number of sub-divisions of the classes ALl to AL7. Although the last of these was never actually
 introduced under the old title of AL7, but
 designated Class 87 with the new “TOPS”
 locomotive codes, the family likeness remains
 very strong despite the detail alterations to the appearance of the latest type.

AEI_4Under the Modernisation Plan proposals it was decided that two types of locomotive – ‘A’ and ‘B’ – would be required. These were for mixed traffic, and freight service, respectively, with an equal number of both types needed, with their different haulage characteristics. This was not how things turned out, with the slower progress in the adoption of continuous brakes on freight trains, only five of the first 100 locomotives were type ‘B’, freight types. Metropolitan Vickers and BTH (as AEI), and English Electric were the builders of this entirely new breed of motive power, with mechanical portions of some constructed at BR’s Doncaster Works, and the North British Loco Co., in Glasgow.

91005 passing Carstairs 1995“Electra” was in effect the final gestation of the first, second and third-generation a.c. locomotive designs to be operated by British Rail, and whilst the ultimate high-speed passenger train, the APT never materialised, it did give rise to the “Pendolino” tilting trains.
