The B class were a class of diesel locomotives built by Clyde Engineering for the Western Australian Government Railways between 1962 and 1965.

History[edit]

The first five B class units entered service in 1962. Three years later, a second batch of five was delivered.[1]

The second batch differed from the first only in having sloping cab sides, to enable the second batch to pass underneath the limited clearance cranes on the Fremantle wharves.[1]

All members of the class spent the whole of their working lives in the Perth metropolitan area, and were written off as a group in September 1984.[1] Some of them have since been preserved.[2][3]
