This page gives a quick and easy decoder between GB timetable code and the relevant operator. Codes were introduced by BR with the 29 September 1996 timetable for its internal train operating units (TOUs) that later became the first privatised train operating companies (TOCs). Note that dates given here are for the GB Passenger Railway timetable period in which the codes appeared. Naturally, where franchise changes took place at dates other than timetable change dates, the new operator's code had to wait until the next timetable. Operating dates and other information are given on the franchises page.

This list also shows codes for organisations that do not or have not run timetabled passenger trains. Some of these (e.g. Railtrack) appeared in the timetable's commercial information pages as a station operator. Others, e.g. Network Rail (On Track Plant), have codes allocated in online and internal systems.

Entries are given alphabetically by code and subsequently chronologically by date. Names are given in the form

Legal name Trading/brand name(s)

All timetable change dates appear on this Rail Chronology page.
