The locomotives were used for heavy shunting tasks in UK industrial sites for clients including British Steel Corporation and the National Coal Board.

[2] Most of the locomotives produced were 3 axle versions of two types - a 50-ton loco (16.5 ton axleload) with a 500 hp V8 cylinder Dorman 8QT engine, and a 75-ton (25 ton axleload) machine with a 12-cylinder engine rated at 750 hp.

[4] An ex-Barrington Cement Works ex-ICI locomotive named Ludwig Mond was acquired in 2010 by the Rutland Railway Museum.

[3][5] As of 2012 locomotives of this type are still in service with Tata Steel Europe in the UK.

In January 2012 the steel works in Lackenby imported ten 1500 kW ex-NSB Di8 Bo'Bo' locomotives for the torpedo wagon trains - this will result in several of the GEC locomotives being scrapped though some are expected to be retained for track renewal and shunting work.
