List of Train Describers

The following list of TD areas was last updated on 4th March 2013.

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
