Business and sector codes

A (one day) comprehensive listing

Last update 14 March 2023

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 a feature list from the links below:

Each passenger train company not only has the ATOC/GB timetable code (see the franchises page), but they also have a business code (two letters) and sector code (two numbers). All the freight companies also have these codes. Passenger operators split the business code into 'profit centres'; these are shown in more detail on the service groups page.

These lists are based on 2015 information with such subsequent developments as are known. There may be historical codes missing from them.

Business codes

Various systems use these two-letter codes, certainly the mainframe for TRUST and logging on codes. Many companies have more than one code depending on how their cost allocations are set up. Legal names are given here where appropriate; names in [square brackets] are trading names where different and helpful.

It is interesting to note that Freightliner has the code DB.

Sector codes

These are two numbers. Older franchises were roughly in the 60-89 series, and new ones start at 20. 'Like for like' franchises tend to keep their original codes.

These codes are used in the CORPUS computer system. Old codes have been retained in CORPUS and some of the descriptions are now questionable and some of the listed codes may never have been used. This may be to ensure they do not get reused within seven years.

Sector codes also have a sub sector code for some TOCs to break down service groups. The sector codes are derived from the eight digit train service codes formally known as profit centre codes; there are thousands of these and some of the real time sites have these codes shown against a particular train schedule.

A train can have more than one service code on its journey perhaps changing at a PTE boundary point. Codes are used for revenue allocation in other computer systems. A Glasgow-Newcastle train has a change of service code at Carlisle to change it from Scotrail to Northern service. Other codes used for accounting appear in the NLC pages.
