History of the TGR 'Y' Class

The Tasmanian Government Railways (TGR) Y Class were designed by English Electric and constructed between 1961 and 1971 at the Inveresk Workshops in Launceston. Eight were built as mainline freight and passenger locomotives, and were based on the Western Australian WAGR 'F' Class and the South Australian SAR 800 Class. 

The Y class were fitted with an English Electric 6SRKT Mark II (Mark III on last two) in-line six turbocharged diesel engine. They have a Bo-Bo wheel arrangement and end-platforms. In line with standard TGR practice of the time, they were fitted with hook-and-link couplers and vacuum train brakes (air on locomotive). With a light tractive weight of only 58 tonnes, a reasonably powerful engine of 825 horsepower (615 kW) and a fairly basic bogie design, gaining traction on long uphill grades was found to be difficult. They were noted to have a tendency to wheel-slip badly. Nevertheless, they were considered successful.

In March 1978 the Y class were included in the transfer of the Tasmanian Government Railways (TGR) to Australian National (AN). With the new transfer of twenty 830 class locomotives from South Australia and later purchase of ZB class and ZC class locomotives from Queensland Rail, the Y class were made redundant.

Many of the Y Class remain preserved, homed across Don River Railway (Devonport), Queen Victoria Museum (Launceston), Tasmanian Transport Museum (Hobart) and Derwent Valley Railway (New Norfolk).
