The Ghana Railways 1851 class were diesel-electric locomotives built by English Electric-AEI Traction for the Ghana Railways in 1969–1970.
Description The design of the 1851 class combined a narrow body, similar to a hood unit, with full-width cabs at each end to provide good visibility. The engine, electrical and control equipment was essentially the same as fitted to the British Rail Class 37 as well as a number of other export locomotives.
The main frame consisted of two fabricated box-section longitudinal members with fabricated box-section cross members. These box sections were sealed to form the fuel tank in the centre of the locomotive.
The bogies were cast steel with axles fully compensated with underslung beams acting on long-travel coil springs. Side bearers were totally enclosed with oil lubrication. The bogies were linked with lateral spring-controlled intercouplers, reducing track stresses and flange wear in curves. To maximise rail adhesion the locomotives were fitted with a wheelslip prevention system and the bogies were designed to reduce weight transfer.
History By 1999 only two remained in service. In 2003 just one, 1864, remained in storage at New Takoradi, but had been scrapped by 2007.
