Class 04 (Drewry Car 204hp Diesel-Mechanical)

The Class 04 was a development of the 0-4-0 shunter the Drewry Car Company built for the LMS before the war (see LMS 7050), the first example being a demonstrator built for the LNER just before nationalisation in 1947 [1]. Series production began in BR days a few years later, being the first attempt to build a standard small shunter [2]. The Class 04 performed a role similar to the Class 03 (which is almost exactly the same mechanically and similar looking) working in small yards and where a lighter locomotive was required. Drewry was more a design and sales company rather than an actual manufacturer (for most of the company's life) and so sub-contracted out the building of the locomotives to the Vulcan Foundry and Robert Stephenson & Hawthorns [3].

Information
Number built: 142
Built: 1948, 1952-62
Builder: Drewry Car Company
Engine: Gardner 8L3 diesel
Power: 204 hp (152 kW)
Wheel arrangement: 0-6-0

As the amount of shunting needed fell in the 1960s BR decided to standardise on the Class 03 for the small shunter role and the Class 04s began to be withdrawn from the late 1960s onwards along with dozens of other small shunter types. All were gone by 1972 though a number were sold for re-use by industrial railways both at home and abroad. Eighteen have been preserved.

LMS 7400 (7050)

The LMS was an early pioneer of diesel traction and built a number of experimental diesel shunters in the early 1930s. Number 7050 (originally allocated the number 7400) was the smallest of these. It was built by Drewry (establishing what would become the very familiar look of their shunters) at the EE Dick Kerr works in Preston [1].

Information
Number built: 1
Built: 1934
Builder: Drewry Car / EE Dick Kerr
Engine: W H Allan 8RS18
(Later) Gardner 6L3
Power: 160 hp (120 kW) (Allan)
153 hp (114 kW) (Gardner)
Wheel arrangement: 0-4-0

Although a small shunter, 7050 had an impressive performance and was able to haul up to 400 tons. It was sold to the War Department in World War 2 and remained in MoD service until being preserved in 1979 [2]. It is during its military service that the original Allan engine was replaced by a Gardner one. It is now part of the national collection at York.
