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A large number of different shunter types were purchased by British Rail and its predecessors, many of which were withdrawn prior to the introduction of TOPS.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