The 1250 class was a diesel-electric locomotive introduced by the Queensland Railways in 1959. They were built by English Electric Australia in Rocklea, Queensland.[1] The design was unusual being a cab unit with a cab similar to the 1200 class but with a narrow long hood.
The first five units had a 1,035 kW (1,390 hp) engine. The subsequent units fitted with a 1,145 kW (1,540 hp) engine and wired for multiple unit operation.
They used on ore traffic on Mount Isa line, and on general freight on the North Coast line and to Wallangarra.[1][2]
A characteristic addition to the 1200 class and 1250 class in 1961 was a sun visor to help reduce glare.
The 1270 class built from 1964 were mechanically very similar to 1255-1266, but were a hood unit.
