The Queensland Railways 8D11 class locomotive was a single-member class of 0-4-4-0 double boilered steam locomotive operated by the Queensland Railways.

History

In 1874, the Vulcan Foundry delivered a 0-4-4-0 locomotive to the Norwegian Government Railways, who refused to accept it. After being rebuilt as works number 850, it was trialled by the Queensland Railways on the Ipswich to Toowoomba line and later purchased.

Numbered 41, it was named Governor Cairns. Per Queensland Railway's classification system it was designated the 8D11 class, 8 representing that it had eight driving wheels, D that it was a tank locomotive and the 11 the cylinder diameter in inches. It was scrapped in 1902.
