Queensland Railways C13 (Dubs) Class Steam Engine
In 1879 Queensland Railways took delivery of two 2-8-0 steam locos built by Baldwin in the United States. In 1883 and 1884 QR took delivery of a further six loco built to the same design but this time the builder was Dubs in the United Kingdom.
These locos were originally referred to as ‘Small Consolidations’ but, along with the two Baldwin locos, were subsequently classified as the C13 class and later still the classification was changed to C13 (Dubs) class to differentiate them from the early Baldwin locos.
At the time these locos were introduced the railways north of Brisbane consisted of a number of unconnected lines reaching inland from a number of ports including Maryborough and Bundaberg and it was to these two centres that the Dubs locos were sent.
These locos were originally referred to as ‘Small Consolidations’ but, along with the two Baldwin locos, were subsequently classified as the C13 class and later still the classification was changed to C13 (Dubs) to differentiate them from the early Baldwin locos.
Four of the locos went to Maryborough and two went to Bundaberg where they were assigned local numbers
| Maryborough Locos | Bundaberg Locos |
| 9 – 112 | 4 – 116 |
| 10 – 113 | 5 – 117 |
| 11 – 114 | |
| 12 – 115 |
During 1904 and 1905 all six locomotives of the C13 (Dubs) class were rebuilt and when the locomotives emerged from the workshops they had a raised boiler, a deeper firebox and the smokebox had been extended. These changes altered the appearance of the locos and the above photo shows the original appearance of the class.
The last locomotive in the C13 (Dubs) class to remain in service was 117 which was used as a washout loco at Toowoomba for some years.
