List of Train Describers

The following list of TD areas was last updated on 26th November 2014, using steps seen from the Opendata TD Feed.

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 location of berths may not be accurate in all locations.

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
• Name - the name of the train describer
• Topic - the name of the topic
• 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

A TD with the name of 'TBA' 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
