This table lists the codes used to identify Train Operating Companies (TOCs) in the various data feeds available from Network Rail. Different feeds use different sets of codes to refer to the same company.

  • Company Name is the name of the Train Operating Company
  • Business Code is a two-character code used within the TRUST system. It is used in the names of the individual train movement feeds.
  • Sector Code is the sector code used to represent the TOC in TRUST messages.
  • ATOC Code is a two-character code used to representing the TOC in the SCHEDULE feed. Non-passenger operators are represented by an ATOC code of ZZ and are subject to obfuscation in the SCHEDULE feed (with the exception of GB Railfreight services).
