The Za class are a class of diesel locomotives built by English Electric Rocklea for the Tasmanian Government Railways in 1973.

History

With the construction of a new line from Launceston to Bell Bay, Tasmanian Government Railways placed an order for four 1752 kW locomotives with English Electric. A further two were delivered in 1976, ZA 6 being the final locomotive built by GEC Australia.[1][2]

In March 1978 the Za class were included in the transfer of the Tasmanian Government Railways to Australian National. From 1982 all had their vacuum brakes replaced with air brakes.[3]

In June 1998 the five in service were renumbered as the 2114 class, ZA4 having been withdrawn.[4]

As of May 2014 all three renaming locomotives are stored. With ZA's 1 and 2 future undecided and ZA 6 preserved by Tasrail staff.
