Type 5 Heavy Freight Locomotives

This photographic album portrays the four classes of locomotives introduced to operate on the British Railways system, prior to Privatisation in 1994. Increasing loads and deteriorating reliability of older classes necessitated the design of new, higher horsepower classes of diesel locomotives to operate the increasing requirement to operate trains handling loads in bulk, such as coal, minerals, fuels etc. The four classes included one American design - the class 59 - which set new standards in haulage capacity and reliability. The other three designs - classes 56, 58 and 60 - were more suitable to their tasks than previous models, but in the case of the class 56, suffered a poor reputation for availability for several years, although the few remaining members of the class have now attained acceptable standards. Of the four classes, a small number of class 56s operate in private ownership, all the class 58s have been withdrawn, but all the class 59s and 60s are in daily use throughout England and Wales.
