UK railway operator service groups

A (hopefully) comprehensive listing

Last update 26 May 2021

Additional information is always gratefully received, whether entirely new records (particularly historical records) or information to fill in gaps or correct errors, via the contact link under the Miscellaneous entry in the navigation bar above. Thank you.

Please select from the links below:

To allocate costs (typically delay and possession compensation) within the industry as a whole, each passenger train operating company is allocated a two letter code. Each TOC, whether franchised or 'open access', groups its services into profit centres (e.g. Central Trains grouped its services centred on Birmingham Snow Hill together and grouped its services centred on Birmingham New Street together). Each profit centre has a two digit identifier applied after the TOC code, usually starting at 01 and working sequentially (some gaps exist). In the Central Trains example, Birmingham New Street services were HG02.

This listing shows the TOC codes and the profit centres. They were mostly derived from the track access contracts in the Office of Rail and Road public register, which the reader is invited to peruse for fuller details of how the cross-industry finances work.

It will be seen that, where a new franchise is broadly the same as a previous one, the code carries forward. New franchises with substantially different geography receive new codes. Names given are the TOC's legal name (all versions used if the name changed during the TOC's life). Trading names, where different, do not appear on this page. Further details are available on the railway operators' licences and franchises pages. Freight and other operators not running regular timetabled passenger services do not have codes.

A separate page shows all companies' (including non-passenger operators) business and sector codes.

It appears that, coincidentally, East Midlands Trains/Abellio East Midlands and South Yorkshire Supertram are the only companies with a code that matches their name.
