@ davidbird - My colleague and I are working on a project involving a driver command that detects the signal ahead and sets it to one of a number of extended states. Signals that are suitable equipped such as Signal BR 1 will display the call-on lights.
The command automatically resets the signal when the train passes by, and the signals do not need to be named.
@Kennilworth - Brian, would you be interested in beta-testing the command?
Best Regards
Trevor
