development of the first generation ac electrics. The Class 87
locomotives were designed specifically for the opening of the final
section of the west coast main line through to Glasgow. The
locomotives body was based on the Class 85/86 locomotives and major
improvements overall came from experiences with the other AL types.
The Class 87's were the last full class to be delivered in rail blue
livery. One machine, 87 101, was built with an experimental thyristor
control, for research into future electric traction, though this
locomotive soon joined the main fleet in normal service.
Equipment: Four GEC type G412AZ traction motors, fully suspended, single reduction gear drive.
Numbers: 87 001 - 87 035, 87 101
Previous No. Series: Originally 35 locomotives were envisaged allocated the numbers E3201 - E3235 though these were never carried.
