The class 04 locomotives were supplied by the Drewry Car Co., who at the time (and for most of its existance) had no manufacturing capability. Drewry sub-contracted the construction work to two builders both of who build other locomotives under the same arrangement. Early locomotives were built by the Vulcan Foundry while later examples were built by Robert Stephenson & Hawthorne. 0-6-0 is also the emergency telephone number in Mexico, similar to the United Statess 9-1-1. ...

A clear line of development can be seen in the class 04s from the 0-4-0DM locomotives built by Andrew Barclay and Drewry/Vunlcan Foundry in the early 1940s. The design continued to develop during the construction period, but this was generally confined to the size of the cab windows and the size of the wheels. Similar locomotives had been built before the first Class 04 and others were build for industrial use. Andrew Barclay & Sons Co. ...

Mechanically, they were identical to the Class 03, with the same 24 littre Gardner engine, 5 speed epicyclic gearbox and the same overall layout. They had a straight bonnet (US: hood) from the front to the rear-mounted cab, unlike the 03's that bulged higher towards the rear (over the larger fuel tank), and the cab's rounded roof met the sides at an angle instead of with a curve as in the 03's, with a lip all the way round. The internal cab layout was almost symetrical to allow the driver to work from either side as required.
They were withdrawn from service earlier than the Class 03, being taken out of service between 1968-1971, though a large number were sold to private industry, allowing many examples to be later bought for preservation. With the reduction in the need for shunters, it was decided to standardise on the Class 03 as a light diesel-mechanical shunter and the Class 08 and 09 as larger, diesel-electric shunters.

The first four of these locomotives were fitted with side skirting and cowcatchers for use on the Wisbech and Upwell Tramway (British law requires locomotives running on unfenced street trackage to be so protected for the protection of pedestrians). These 'Tramway' Class 04 locomotives was the basis for "Mavis the Quarry Diesel" in the Thomas the Tank Engine books and TV Series. In railroading, the pilot is the device mounted at the front of a locomotive to deflect obstacles from the track that might otherwise derail the train. ...

The engine is a Gardner 8-cyl, 4 stroke 8L3 developing 204 hp at 1200 rpm, connected to a Wilson-Drewry CA5 R7, 5-speed epicyclic with RF11 spiral bevel reverse and final drive unit mounted on a 'Jack shaft'. The drive to the wheels was by couping rods from the jack shaft.
