1170 Class Background
The 1170 class (initially numbered the 1500 class, and before that, the 1270 class) were a class of diesel locomotive built by Walkers Limited, Maryborough for Queensland Railways between 1956 and 1958. The 1170 class were intended as a replacement for the PB15 class steam locomotives on branch lines. They were built by Walkers Limited in Maryborough under licence from GE Transportation. The class were popularly known as 'Paw Paws' after a racehorse, which in turn was named after a character in a contemporary cartoon strip. They spent most of their working lives based at Townsville but in later years were used around Brisbane and the southern region of the state as shunters.
