Line diagram of Class 1400 locomotives

They were ordered primarily to replace steam locomotives then still in use on CP. Designed and engineered by English Electric, they are closely modelled mechanically on the British Rail Class 20 locomotives but using a more powerful intercooled 1,330 bhp 8CSVT version of the Class 20's 8SVT engine. The locomotives were designed for the 1,668 mm (5 ft 5+2132 in) Iberian gauge and larger loading gauge than possible in United Kingdom. The first ten were built in England at the Vulcan Foundry in Newton-le-Willows, with the remaining locomotives assembled in Portugal by Sorefame.[2] The locomotives share many components with the larger and more powerful Class 1800.

During the early years of the 21st century, some were sold for further service in Argentina, but as of 2012 many remain in service with CP.
