The following list of TD areas was last updated on 4th December 2017.

Specific information relating to each TD (such as ECS's/SOP's which give the S-Class data mapping, Block schematics which show all the berth steps within a TD and stepping tables which show which conditions must be met in order for description to step) can be found by clicking on the link in the 'ID' column.

User contributed maps, where available, show signal berths and their locations in relation to the railway. Because maps have been compiled using steps seen from the feed, the placement of berths may not be accurate in all locations.

General information relating to entire signalling areas can be found by clicking the link in the 'topic' column. This may include track and signalling maps released by Network Rail.

  • Note: As of September 2017 NR have decided still not to continue fulfilling requests to provide TD technical data (SOP's, Stepping schematics etc) - this has been to internal review & they are still blocking the requests. I have since been put in contact with a member of the TED team, and am exploring some avenues with them directly before I use the brute force of the ICO to try and crack them. In a nut-shell NR say the release of the technical information is a security risk to railway systems and have decided that no more will be released till such time they can work out the specifics. It has been acknowledged that this goes against the spirit of what's been done up till now, and that it effectively means a lot of the stuff on the NROD feeds is technically useless to most people as they rely on the technical documentation to build products etc. Once we have had a chance to have a direct conversation with the new contact I'll update this section... //Q

The column headings are as follows:

  • ID - identity of the train describer in TD messages. This is not necessarily the same as the plated signalbox ID. Where a link is provided you will find specific details relating to that TD area.
  • Name - the name of the train describer
  • Topic - the name of the topic - if unspecified, data is available on the 'all area' feed. Where a link is provided you will find generic details relating to that area.
  • SIG - whether signal aspects (on/off) are available
  • RTE - whether route set indications are available
  • TRS - whether Train Ready To Start (TRTS) indications are available
  • TRK - whether track occupation (track circuit or axle counter) indications are available
  • PTS - whether points (normal/reverse) indications are available
  • LXG - whether level crossing barrier control indications are available
  • Commissioning - the date the train describer was commissioned or when it is expected (day/month/year).
  • Abolished - the date the train describer was abolished or when it is expected (day/month/year).

A TD with the name of 'TBD' indicates a train describer which is planned, but details are not yet available. A '?' in one of the six S-Class columns indicates that this detail is not currently known
