The CL class is a class of diesel locomotives built by Clyde Engineering, Granville for the Commonwealth Railways in several batches between 1970 and 1972. The class was the last in the world to be built with the Electro-Motive Diesel bulldog nose but differed from previous builds in having a mansard roof.
In 1968 Commonwealth Railways placed an order for five 2237 kW locomotives with Clyde Engineering to operate services on the Trans-Australian Railway from Port Pirie to Kalgoorlie. They were mechanically similar to the Western Australian L class of 1967. The initial design was to have a Do-Do wheel arrangement and a USA style EMD FP45 cab. This was later changed to a streamlined carbody and conventional Co-Co wheel arrangement
The first locomotive was completed in January 1970, with two further orders resulting in 17 locomotives being built with the last delivered in October 1972. Their operating sphere was extended through to Perth on Indian Pacific services and for a time in the 1970s they operated through to Lithgow, New South Wales. In July 1975, all were included in the transfer of Commonwealth Railways to Australian National. The CLs began to operate to Alice Springs and Adelaide when these were converted to standard gauge in 1980 and 1983. In 2004 they began to operate to Darwin following this line opening.
