The MRWA E class was a single member class of diesel-hydraulic shunting (switching) locomotive built by Commonwealth Engineering, Bassendean, Western Australia, for the Midland Railway of Western Australia (MRWA) in 1957. The locomotive was later owned and operated by the MRWA's successor, the Western Australian Government Railways (WAGR).

Service history[edit]

The single member of the class, E30, entered service with the MRWA in February 1957 as its first diesel powered locomotive.[1] E30 also ended up being 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 WAGR in 1964.[2]

The locomotive was withdrawn from WAGR service on 18 February 1983 (1983-02-18), and has since been preserved at the Rail Heritage WA Railway Museum at Bassendean, Western Australia.[2]
