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
