History

In 1884 Dübs & Co delivered five 2-8-2T locomotives to the Queensland Railways. Three were delivered to the Southern & Western Railway and one each to the Central (Rockhampton) and Great Northern (Townsville) Railways. The latter was transferred to the Central Railway without use. Per Queensland Railway's classification system they were designated the 8D15 class, the 8 representing the number of driving wheels, the D that it was a tank locomotive, and the 15 the cylinder diameter in inches.^[1]

Two were converted to tender engines in 1890/91. All were later reboilered. The tank engines were written off in October 1922, while the tender locomotives, having spent their final years hauling limestone and water trains to Mount Morgan gold mine, followed in 1938.^[1]
