The Diesel Electric Rail Motor (DERM) was a type of railmotor operated by the Victorian Railways in Australia.

[3][4] The bodies of the remaining nine were constructed at Newport Workshops using imported equipment and electrical components, and placed in service between 1930 and 1931.

The first-class end of the vehicle was moved towards the centre, closer to the engine, but providing a smoother ride by averaging the suspension of both bogies rather than just one.

[10][11] Those "Super DERMs" were a familiar sight on the adjoining Mornington and Stony Point lines prior to the early 1980s.

Four are operational, with the remaining five in various conditions, generally as a source of spare parts with long-term restoration in mind.
