Over 200 of the diminutive Ruston 48DS were built between 1937 and 1967, becoming immensely popular for small industrial sites who couldn't afford the expense of a steam shunting locomotive or worked with hazardous materials where such a locomotive would be unsuitable. The design was also supplied to the War Department and variations in different gauges were supplied around the world.
