what is it?

The 421 class are a class of diesel locomotives built by Clyde Engineering, Granville for the Department of Railways New South Wales in 1965/66. These mainline locomotives were a follow on from the 42 class. The 421s retained the classic bulldog nose as with the other Clyde built GM and S locomotives at one end, but featured a flat-cab at the other end.
