List of British Rail modern traction locomotive classes

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

This page lists every locomotive allocated a TOPS classification and all modern traction (e.g. diesel, electric, gas turbine, petrol) stock used on the mainline network since 1948 (i.e. British Railways and post-privatisation).

Diesel locomotives[edit]

The 1955 diesel locomotive classes are given in brackets where applicable.

A large number of different shunter types were purchased by British Rail and its predecessors, many of which were withdrawn prior to the introduction of TOPS. The tables below attempt to list the different types and the different classifications used to describe them as clearly as possible:

Small shunters: under 300 hp[edit]

Shunter classes are listed by 1955 class, which puts TOPS classes in ascending order, and generally puts 1948 and 1962 classes in ascending order. Unclassed shunters are placed at the start of the table; TOPS class 07 has been placed so its 1962 class is in the logical place.

Locomotive class are listed by TOPS class. Locomotives for TOPS classes 24 and 26 have their original sub-classes shown, as each wholly comprised locomotives from a distinct 1962 class. Class 21 (II) has sub-classes shown as these are superficially similar but mechanically different types grouped into a single class.

Miscellaneous locomotives[edit]

Type Class / number(s) Information Image
Channel Tunnel Class 22 (II) SNCF Class BB 22200 class dual voltage electric locomotives used for freight duties through the Channel Tunnel by Railfreight Distribution during 1994-95, prior to the availability of the dedicated Class 92 locomotives. Allocated as Class 22 under TOPS. BB22394-Antibes.jpg
Class 9000 Dedicated locomotives used only on Eurotunnel Shuttle services through the Channel Tunnel between Foklestone & Calais. No TOPS classification. Eurotunnel 9015 Nord-Pas-de-Calais.jpg
Class 0001 Diesel-electric locomotives used for rescue purposes on the Channel Tunnel network. Classed as 21/9 under TOPS Railion 6450.jpg
Class 0031 Diesel locomotives used for maintenance purposes by Eurotunnel on the Channel Tunnel network. No TOPS classification
Departmental Class 97 General departmental locomotives, used for special or engineering duties. Were therefore of many different classes, lumped together for numbering purposes. Forty-seven locomotives allocated Class 97 numbers, including five in subclass 97/6. Talsarnau railway station MMB 07 97303.jpg
Class 97/6 Five diesel shunting locomotives purpose-built for departmental duties on the Western Region in 1953 (number 97650) and 1959 (numbers 97651-654), and originally numbered PWM650-4. Withdrawn 1987-2005. Class 97/6 (97 651, also known as PWM651) at Pitsford and Brampton station
Various Pre-TOPS Departmental Locomotives
Steam Class 98 Used to cover all steam locomotives used on the mainline in Britain. Had particular usage for the three Vale of Rheidol Railway steam locomotives that remained in BR's ownership after the end of mainline steam traction in August 1968, and numbered 98007-98009, although in practice the locomotives retained their former (GWR) numbers 7-9.
Also used for privately owned steam locomotives registered to run on the mainline since 1971, with numbers allocated in the following way:
  • First two digits: 98 (for class 98)
  • Third digit: 0-9 representing the Power Class 0-9
  • Fourth and fifth digits: The last two digits of the locomotive's original number. If this would duplicate an existing number, then the number is increased by 1
Class 98 Vale of Rheidol locomotive taking on water
Petrol 15097-15099 Petrol powered locomotives built by Simplex, introduced 1919-1925 by the GER and NBR (later LNER (1 built by LNER)), and subsequently inherited by BR. Stratford locomotive depot geograph-2382583-by-Ben-Brooksbank.jpg
Gas turbine 18000 Prototype mainline gas turbine locomotive built for BR in 1949 by Brown Boveri. Had been ordered by GWR in 1940, but construction was delayed due to World War II. 18000 at the ORE Arsenal Test Centre in 1988
18100 Prototype mainline gas turbine locomotive built for BR in 1951 by Metropolitan-Vickers. Had been ordered by the GWR in the 1940s, but construction was delayed due to World War II.

Class 99[edit]

SS Invicta at Newhaven in 1971

When British Rail implemented the TOPS system for managing their operating stock, ships capable of carrying rail vehicles were incorporated into the system as Class 99. In order to circumvent restrictions of the application software, these ships were entered on TOPS as locomotives, 'hauling' the trains which they carried on board.

Builders' demonstrators[edit]

These were locomotives built and owned by private firms, but used by British Railways to test them.

Unbuilt locomotives[edit]

A number of TOPS class numbers were allocated to proposed locomotives, both diesel and electric, which for many reasons were not proceeded with.

Compared with the Class 56, the reclassified Class 69 locomotives, will feature an enhanced driving cab environment as well as improved electronic control system.
