Queensland B15 class locomotive

The Queensland Railways B15 class locomotive was a class of 4-6-0 steam locomotives operated by the Queensland Railways.

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 the 15 the cylinder diameter in inches. A further six were acquired In 1919 when the Queensland Railways took over the Chillagoe Railway & Mining Co.

Problems with broken rails saw three sets of 45 inch 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.
