Class B12

The B12 class steam locomotive was a 2-6-0 locomotive of the Queensland Railways (QR).[1]

The locomotives operated on 1,067 mm (3 ft 6 in) gauge. The “B”, is used to identify the number of coupled wheels, being six coupled wheels for the B12 class, followed by numerals indicating the cylinder diameter of twelve inches (305 mm).

All were withdrawn from Queensland Railways service by 1929 and most were scrapped, however the remains of number 28 are derelict at Normanton and components of number 40 are at Cooktown.

Number 31 was sold to the Aramac Shire Tramway in 1911 and remained in service until 1939. Although it was condemned and copper in the boiler sold for scrap, the remainder of the locomotive remained largely intact until 1963. The boiler is now privately owned and stored at Kallangur. The remainder of the locomotive and tender are still at Aramac.
