The '''MRWA E class''' was a single member class of diesel-hydraulic [[Shunting (rail)|shunting]] (switching) locomotive built by [[Commonwealth Engineering]], [[Bassendean, Western Australia|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== The single member of the class, E30, entered service with the MRWA in February 1957 as its first diesel powered locomotive.<ref>[http://www.perth.republika.pl/Diesel-.pdf Part 3 - Dieselization] {{Webarchive|url=https://web.archive.org/web/20140201234412/http://www.perth.republika.pl/Diesel-.pdf |date=1 February 2014 }} Perth Republika</ref> E30 also ended up being the company's only Western Australian made locomotive.{{sfn|Gunzburg|1989|pp=40–44, 49}}
Together with the rest of the MRWA's assets and operations, E30 was taken over by the WAGR in 1964.{{sfn|Gunzburg|1989|pp=40–44, 49}}
The locomotive was withdrawn from WAGR service on {{end date|1983|2|18|df=y}}, and has since been preserved at the [[Rail Heritage WA]] Railway Museum at [[Bassendean, Western Australia]].{{sfn|Gunzburg|1989|pp=40–44, 49}}
