British Rail BEMU
Experimental battery electric multiple unit
The British Rail BEMU was an experimental two-car battery electric multiple unit (BEMU), converted from the prototype Derby Lightweight Diesel multiple units. The train was powered by many lead-acid batteries, and was used on the Deeside Railway from Aberdeen to Ballater in Scotland from April 1958 until it was finally withdrawn in December 1966. The North of Scotland Hydro-Electric Board initiated the design and was a joint sponsor. The board promised to supply power at three farthings per unit for a fixed two-year period.[1] It provided an 11kV supply to a charger at Aberdeen's platform 1 and a 6.6kV supply to a charger at Ballater.[2]
