Wuiske Models RTR049 1720 Class #1757 Origional with Logo HOn3½ Scale

Class leader 1720 first made an appearance in Queensland in 1966 and were a higher-powered version of the 1700 class. These units quickly proved themselves in all forms of traffic from branch line mixed goods services, suburban services through to general freight and livestock trains. Most of the class members are still in traffic today as the last 60 tonne locomotives operating regularly on the Queensland Network.
