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==
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.
Channel Tunnel	Class 9000 	Dedicated locomotives used only on Eurotunnel Shuttle services through the Channel Tunnel between Folkestone & Calais. No TOPS classification.
Channel Tunnel	Class 0001 	Diesel-electric locomotives used for rescue purposes on the Channel Tunnel network. Classed as 21/9 under TOPS
Channel Tunnel	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.
Departmental 	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 Withdrawn 1987–2005.
Departmental 	Various Pre-TOPS Departmental Locomotives	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 (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 	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.
Gas turbine 	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.

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