History Edit
The prototype locomotive was built in 1947 and served as a departmental shunter at Hither Green depot as number DS1173, 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.
Design evolution Edit
A clear line of development can be seen in the Class 04 from the 0-4-0DM locomotives built by Andrew Barclay and Drewry/Vulcan Foundry in the early 1940s. Similar 0-6-0DM locomotives had been built before the first Class 04, and others were built for industrial use.
The design continued to develop during the construction period, although this was generally confined to minor changes, including the diameter of the wheels.
The first batch (4 engines numbered 11100-11103, later D2200-D2203) were equipped for street-running (see below).
The second batch (6 engines numbered 11105-11110, later D2204-D2209) were fitted with conical exhaust stacks (the first batch initially had a plain exhaust "hole", later having a long, thin, and straight exhaust pipe added) and shaped cab front windows (instead of the rectangular windows of the first batch); these changes continued on all subsequent batches.
From the fourth batch (commencing with 11121, later D2215) the small cab side window of the earlier batches was replaced with a much larger window, the rear half of which slid open. The wheel diameter was also increased from 3'3" to 3'6".
From locomotive D2274 onwards, the wheel diameter was again increased, from 3'6" to 3'7". The front running plate was cut out and the steps inset to provide a safer location for a shunter riding on the locomotive; to facilitate this, the locomotive straight air brake reservoir tank was relocated underneath the centre of the running plate. This is the version depicted by the Airfix/Dapol plastic kit.
Use on tramways Edit
The first four of these locomotives (11100-11103, later D2200-D2203) were fitted with side skirting and cowcatchers for use on the Wisbech and Upwell Tramway and on the Yarmouth Docks tramway system, since British law requires locomotives running on unfenced street trackage to be so equipped for the protection of pedestrians and animals. At least two later engines (11111/D2210 and 11113/D2212) were also fitted with cowcatchers and skirting for use on the Ipswich docks tramway system.
Usage Edit
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, leading to the withdrawal of the class 04 engines.
Baguley Cars Ltd (later Baguley (Engineers) Ltd, then E. E. Baguley Ltd) was a British engineering company, specialising in railway locomotives. it was founded in 1911 by Ernest E. Baguley and subsequently acquired by Drewry Car Co to form Baguley-Drewry in 1964.P
