The Tasmanian Government Railway Z class are a class of diesel locomotives built by English Electric, Rocklea for the Tasmanian Government Railways in 1973. They were a development of the Western Australian Government Railways R class and were the last of a line of very successful locomotives fitted with the English Electric 12CSVT Mk II engine.
With the construction of the new line from Launceston to Bell Bay, the Tasmanian Government Railways placed an order for four 1752 kW locomotives with English Electric. However, with the locomotive still under development, it was decided to purchase four 1380 kW locomotives that were an evolution of the Western Australian RA class locomotives with a low nose profile and vacuum brakes. [1] [2] At 96 tons, they were considerably heavier than the previous heaviest locomotives on the network, the Y class at 58 tons, requiring significant upgrades to infrastructure. [3] The first was delivered in December 1972. [4] [5]
In March 1978 the Z class were included in the transfer of the Tasmanian Government Railways to Australian National. In 1984/85 all had their vacuum brakes replaced with air brakes. [6] [7]
In June 1998, they were renumbered as the 2110 class. [8] All four locomotives were modified for driver-only operation between 1998 and 2001, by having their noses lowered further and the size of the front cab windows increased.
All remained in service with TasRail until stored in May 2014 with the entry into service of the new TR class.
In 2022, The Q Train acquired Z1 and Z4 for revenue use on their restaurant rail services on the Bellarine Railway. Z1 was delivered in March and Z4 in May. [9] Z2 and Z3 were donated to the Don River Railway.

The British Rail Class 97/6 0-6-0 diesel shunting locomotives were purpose-built for departmental duties by Ruston & Hornsby at Lincoln in 1953 (97650) or 1959 (97651-654). There are minor technical differences between 97650 and the 1959 batch.

The Australian National Railways Commission was an agency of the Government of Australia that was a railway operator between 1975 and 1998.

The company operated narrow gauge trains in Tasmania and standard gauge trains in New South Wales and Victoria. It was formed as a joint venture with Tranz Rail owning 67% and Wisconsin Central 33%.

The NZR WF class were steam locomotives designed, built and used by New Zealand Railways (NZR). Their wheel arrangement is described by the Whyte notation 2-6-4T and the first members of the class entered service in 1904. The locomotives were tank engines designed by the Railways Department's Chief Mechanical Engineer A. L. Beattie, and were mainly built for suburban duties such as those between Christchurch and Lyttelton. They also saw main-line service in the Taranaki region, but most of the class members were assigned to branch line and local services throughout the country. Two were experimentally converted to oil burners in 1909-1910. The tests were satisfactory, but as coal was much cheaper than oil at the time, no further conversions took place.
