- List of British Rail modern traction locomotive classes
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.eBritish Rail ways and post-privatisation).Diesel locomotives
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British Rail and its predecessors, many of which were withdrawn prior to the introduction ofTOPS . 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
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.
* Relation between TOPS, 1948, 1955 and 1962 classes, and 1948, 1957 and TOPS numbers (unless otherwsie given):
Type 2 locomotives: 1001 - 1499hp
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.
Type 5 locomotives: over 3000hp
Miscellaneous locomotives
Class 99
When British Rail implemented the TOPS system for managing their operating stock, part of their shipping fleet was incorporated into the system as Class 99, in order to circumvent some of the restrictions of the application software.
Builders' demonstrators
These were locomotives built and owned by private firms, but used by
British Rail to test them.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.See also
