Wickness Models Soundscape Class 04 Manufacturer: - Wickness Models Project number: - WM04-1S Project version: - SSV1-Hedgerow Class 04 Power type Diesel-mechanical Builder Drewry Car Co., at Vulcan Foundry and Robert Stephenson and Hawthorns Build date 1948 (D2341); 1952–1962 (D2200-2340) Total produced 142 The British Rail Class 04 was a 0-6-0 diesel-mechanical shunting locomotive class, built between 1952 and 1962 and was the basis for the later Class 03 built in the British Railways workshops. However, the first locomotive to be built to the design was actually DS1173, in 1948, which served as a departmental shunter at Hither Green depot, before being transferred to the capital stock list as D2341 in 1967. The Class 04 locomotives were supplied by the Drewry Car Co., which at the time (and for most of its existence) had no manufacturing capability. Drewry sub-contracted the construction work to two builders both of whom built other locomotives under the same arrangement. Early locomotives (including DS1173) were built by Vulcan Foundry and later examples were built by Robert Stephenson and Hawthorns Mechanically they were identical to the Class 03, with the same 24 litre 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 03s which 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, with a lip all the way round. The internal cab layout was almost symmetrical to allow the driver to work from either side as required. The engine is a Gardner 8-cyl, 4-stroke 8L3 developing 204 hp (152 kW) 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 jackshaft. The drive to the wheels was by coupling rods from the jackshaft. The class was distributed throughout the British Railways system, but the significant decline in the traffic for which they were designed resulted in a large surplus of shunting engines on the network. With this 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 The Class 04s were withdrawn from service earlier than the Class 03, being taken out of service between June 1967 and May 1972, with some sold for re-use by industry. Four were exported to Italy about 1972, with D2289 reported as still in service.

Notches up regardless of speed. Diesel notch down – notch down as above. Note: once engaged manual notching remains in effect until locomotive is stopped and notch point is at idle. .
