The **MRWA E class** was a single member class of diesel-hydraulic [shunting](/source/Shunting_(rail)) (switching) locomotive built by [Commonwealth Engineering](/source/Commonwealth_Engineering), [Bassendean](/source/Bassendean%2C_Western_Australia), Western Australia, for the [Midland Railway of Western Australia](/source/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](/source/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.[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The locomotive was withdrawn from WAGR service on 18 February 1983 (1983-02-18), and has since been preserved at the [Rail Heritage WA](/source/Rail_Heritage_WA) Railway Museum at [Bassendean, Western Australia](/source/Bassendean%2C_Western_Australia).[2]
