List of British Rail modern traction locomotive classes

Summary

This article 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A large number of different shunter types were purchased by British Rail and its predecessors, many of which were withdrawn prior to the introduction of TOPS.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
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.

Class 9000
 

Dedicated locomotives used only on Eurotunnel Shuttle services through the Channel Tunnel between Folkestone & Calais. No TOPS classification.

Class 0001
 

Diesel-electric locomotives used for rescue purposes on the Channel Tunnel network. Classed as 21/9 under TOPS

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.

Class 97/6
 
Class 97/6 (97 651, also known as PWM651) at Pitsford and Brampton station

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.

Various Pre-TOPS Departmental Locomotives
Steam Class 98
 
Class 98 Vale of Rheidol locomotive taking on water

Used to cover all steam locomotives used on the mainline in Britain. Had particular usage for the three Vale of Rheidol Railway steam locomotives (and one VoR 0-6-0DH) 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
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.

Gas turbine 18000
 
18000 at the ORE Arsenal Test Centre in 1988

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.

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. Class 99 has now been allocated to a class of bi-mode locomotives.

Builders' demonstrators edit

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