Janus and Taurus were two shunting locomotives by the Yorkshire Engine Company and loaned to British Railways for demonstrations. However, BR did not buy any production versions after testing. At least one other Yorkshire Engine Company locomotive was loaned to British Railways in the 1960s.
British Rail HS4000
HS4000, named "Kestrel", was a prototype high-powered mainline diesel locomotive built in 1968 by Brush Traction to demonstrate its wares to British Railways. The name came from Hawker Siddeley (the owner of Brush) 4000 hp (the power rating of its Sulzer engine).
British Rail GT3
GT3 was a prototype mainline gas turbine locomotive. It was built in 1961 by English Electric at their Vulcan Foundry in Newton-le-Willows to demonstrate its wares to British Railways. It was designed by Vulcan engineer J. O. P. Hughes and the project was started in the early 1950s. Externally, it resembled a steam tender locomotive. In the case of GT3, the tender carried diesel fuel.
British Rail DP2
DP2, meaning Diesel Prototype number 2, was a prototype Type 4 mainline diesel locomotive built in 1962 by English Electric at their Vulcan Foundry in Newton-le-Willows to demonstrate its wares to British Railways. As the Deltics were then in production, it was decided to produce the locomotive on the same production line; the bodyshell used for DP2 reputedly being the eighteenth made. While DP2 looked like a Class 55 locomotive in outline, there were many detail differences; particularly the large bodyside radiator vents at one end, and the single roof fan as opposed to the four symmetrically placed fans on the Deltics. These differences were the external effect of DP2 being totally different from the twin-engined Deltics internally, being the forerunner of the Class 50.
British Rail DP1
DP1, or Prototype Deltic is a demonstrator locomotive built by English Electric in 1955. This locomotive resulted in 22 similar locomotives being ordered by British Rail, which became their Class 55.
British Rail DHP1
DHP1, meaning Diesel Hydraulic Prototype number 1, was a prototype Type 3 mainline diesel locomotive built in 1965 by Clayton to demonstrate their wares to British Railways. It was designed for mixed traffic work, having steam heating facilities for working passenger trains. It was painted red, with the cab area above bonnet-level height painted cream.
British Rail D0260
D0260, named "Lion", was a prototype Type 4 mainline diesel locomotive built in 1962 by the Birmingham Railway Carriage and Wagon Company, in association with Sulzer and Associated Electrical Industries, at their Smethwick works in Birmingham to demonstrate their wares to British Railways. The locomotive’s number was derived from its works number, DEL260.
British Railways D0226
D0226 and D0227 were two prototype diesel shunting locomotives built in 1956 by English Electric at its Vulcan Foundry in Newton-le-Willows to demonstrate its wares to British Railways. They originally carried numbers D226 and D227, their Vulcan Foundry works numbers, but these were later amended to avoid clashing with the numbers of new Class 40 locomotives.
British Rail 18100
British Rail 18100 was a prototype main line gas turbine-electric locomotive built for British Railways in 1951. It was built by Metropolitan Vickers, Manchester. It was ordered by the Great Western Railway in the 1940s, but construction was delayed by World War II. It spent its working life on the Western Region of British Railways, operating express passenger services from London Paddington station.
It was rebuilt as an electric locomotive in 1958 and became British Rail Class 80. It was scrapped in 1973.
British Rail 18000
British Rail 18000 was a prototype mainline gas turbine-electric locomotive built for British Railways in 1949. It was built by Brown, Boveri & Cie. It was ordered by the Great Western Railway in 1940, but construction was delayed by World War II. It spent its working life on the Western Region of British Railways, operating express passenger services from London Paddington station.
The locomotive is preserved at Didcot Railway Centre.
LNER Class Y11
LNER Class Y11 was a class of petrol powered 0-4-0 locomotives built by Motor Rail & Tram Car Company Limited under their "Simplex" brand and introduced in the years 1919–1925 for the London and North Eastern Railway (LNER). Their British Railways numbers were 15097–15099.
British Rail Class 97
British Rail reserved the TOPS Class 97 designation for departmental locomotives. These were used for special or engineering duties. They were therefore of several different classes, lumped together for numbering purposes. Some locomotives were converted from redundant engines, whilst others were purpose built. In 2008, Network Rail once again used Class 97 for signalling test locomotives (Class 97/3).
British Rail Class 97/6
The British Rail Class 97/6 0-6-0 diesel shunting locomotives were purpose-built for departmental duties by Ruston & Hornsby at Lincoln in 1953 (97650) or 1959 (97651-654). There are minor technical differences between 97650 and the 1959 batch.
British Rail Eastern Region departmental locomotives
In 1952, the Eastern Region of British Rail introduced its own series for departmental (non-revenue earning) vehicles, including locomotives. Numbers were allocated from 1 to 1000, with blocks of 100 numbers allocated to specific types of vehicle.
SR departmental locomotives
The Southern Railway numbered its departmental (non-revenue earning) stock, both locomotives and carriages in a series starting at 1S. The series was retained by the Southern Region of British Rail, but amended so that the numbers carried a 'DS' prefix instead of an 'S' suffix. This page lists the locomotives numbered in this series, including steam, diesel and electric locomotives.
British Rail departmental locomotives
Before the introduction of the Total Operations Processing System, Class 97 was issued to self-propelled locomotives in departmental (non-revenue earning) use, British Rail had such locomotives numbered in a variety of series, together with locomotives that were no longer self-propelled. See Also:
British Rail Class ES1
British Rail Class ES1 was a class of two electric locomotives commissioned by the North Eastern Railway in 1902. They were of steeplecab design.
British Rail Class EF1
The British Rail Class EF1 ("Electric Freight 1") was a class of electrically powered locomotives used by British Rail in England. They were used during the pre-TOPS period. They were also classified as British Rail Class EB1 for a short period of time, although only a single locomotive was completely modified to "EB1" condition.
British Rail Class EE1
British Rail Class EE1 was an electric locomotive commissioned by the North Eastern Railway in 1922. Ownership passed to the London and North Eastern Railway in 1923 and to British Railways in 1948.
British Rail Class EB1
The British Rail Class EB1 ("Electric Banking 1") was an electrically powered locomotive used by British Rail in England. It was used during the pre-TOPS period. The other NER electric locos built at the same time were classified as EB1 but were never modified, they later became British Rail Class EF1.
SNCF Class BB 22200
The BB 22200 is a class of electric locomotives in service with the French railways SNCF, built by Alsthom between 1976-1986. They are a polycurrent version (1500 CV direct current and 25 kV 50 Hz AC) of the BB 7200 and BB 15000 classes, with which it shares the exterior appearance. Thanks to this characteristic they can run in all French electrified lines.
