The Queensland Railways B15 class locomotive is an old class of 4-6-0 engines operated by the Queensland Railways.
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 of 92 engines by 1899. Per Queensland Railway's classification system they were designated the B15 class engine, B representing they had three driving axles, and 150NaN0 diameter cylinders. A further six engines 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 450NaN0 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]
Two examples are preserved.
