The Belgians had designed 600 mm gauge 4-6-2T locomotives as early as in 1900–1901 for Chemins de fer du Calvados.

A little heavier 14-ton type was designed and an order was placed for Weidknecht to produce these locomotives for the 600 mm gauge lines in Morocco.

[citation needed] When the Great War broke out in August 1914 the French lost most of their locomotive building capacity in Northern France to the German-occupied area.

Three steam locomotive type drawings were sent to Baldwin Works (finance guaranteed by the French Government) for production of C n2t, 2′C n2t, and light Mallet B′B n4v for 600 mm (1 ft 11+5⁄8 in) gauge lines.

Indian North Western Railway received fifty locomotives, numbered NWR No 1–50, many of which later operated at sugar mills in various parts of the country.

This locomotive worked on a sugar mill in Mackay and prior to the opening of Dreamworld in 1981 after purchase was heavily modified, including a tender, Wild-West style chimney, and conversion to oil-firing.
