History

In 1889 the first B15 class locomotives built by Nasmyth, Wilson & Co entered service. Further orders from Evans, Anderson, Phelan & Co, Yorkshire Engine Company and Walkers Limited saw the class total 92 by 1899. Per Queensland Railway's classification system they were designated the B15 class, B representing they had three driving axles, and 15-inch (381 mm) diameter cylinders. A further six were acquired In 1919 when the Queensland Railways took over the Chillagoe Railway & Mining Co.[1][2][3]

Problems with broken rails saw three sets of 45-inch (1,143 mm) driving wheels acquired from the South Australian Railways and fitted to 336 at North Ipswich Railway Workshops in November 1900. Judged a success, most others were fitted over the next 30 years. They spent most of their life operating out of Cairns.[1][2][3][4]
