Queensland 6D13½ class locomotive

The Queensland Railways 6D13½ class locomotive was a class of 0-6-0T steam locomotives operated by the Queensland Railways.

History
In 1904 the North Ipswich Railway Workshops assembled six 0-6-0T locomotives. The wheel sets came from B15 class locomotives and the cylinders have been purchased for an aborted project. Per Queensland Railway's classification system they were designated the 6D13½ class, 6D representing they were a tank locomotive with six wheels, and the 13½ the cylinder diameter in inches.

They were generally used as shunters in Brisbane, but on occasions were used in Toowoomba and Warwick. In 1937-1938 all were converted to 0-6-0 tender locomotives and reclassified as the B13½ class with tenders from B13 and C15 class locomotives.
