The E class was a class of diesel locomotives built by Commonwealth Engineering, Bassendean for the Midland Railway of Western Australia in 1957. It was later sold to the Western Australian Government Railways.


The single member of the class, E30, entered service with the Midland Railway of Western Australia in February 1957 as its first diesel powered locomotive.[1] E30 was the company's only Western Australian made locomotive.[2]

Together with the rest of the MRWA's assets and operations, E30 was taken over by the Western Australian Government Railways in 1964.[2]

The locomotive was withdrawn on 18 February 1983, and preserved by Rail Heritage WA, Bassendean.[2]
