The British Rail Class 84 was a 25 kV AC electric locomotive that operated on the West Coast Main Line of the London Midland Region. As part of the modernisation of the West Coast Main Line, which included electrification, 100 locomotives of five types were acquired from different manufacturers.
Ten Class AL4 locomotives numbered E3036 - E3045 were built in 1960 by the North British Locomotive Company in Springburn, Glasgow, to a design by GEC. Sole surviving example now in national collection.
