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.^[1]
