Developed in the 1950s, the English Electric Type 1 was the first major step on British Railwayspath to dieselisation. After many trials and failures, the Type 1 showed promise as a 1000hp (746 kW) locomotive, and between 1957 and 1968 a total of 228 would be produced. The Type 1s took over from steam locomotives of equivalent power, primarily working light, mixed-freight traffic throughout the midlands and in Scotland. Unlike newer locomotives, the Type 1s featured a rather unique single cab design. The cab, situated at the rear of the locomotive, has controls facing in either direction and gives the locos a tank engine-like appearance, with the diesel engine and on-board equipment sat much like how a firebox and boiler would, in front of the cab. Another steam-like feature was the headcode discs adorning each end of the loco. The first 127 Type 1s were built as such.
