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.

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
• 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
