Electric locomotives of the British Railways

摘要

The paper gives a general description of electric locomotives built for service on British Railways, but assumes that the usual system of series-parallel contactor control of traction motors, with field weakening by diversion or tap, issufficiently well known to need no detailed description here. The locomotives described are all d.c. machines and operate either at 630????????660 volts or at 1,500 volts. Interesting features of the various designs are described, some operatingresults are shown, and there is a note on the bogie arrangements on the Eastern Region and Southern Region locomotives. Inview of their unorthodox control system, the Southern Region locomotives have been given special attention, and mention is made of the work now in hand for future locomotive designs on this Region.
