I could use a semaphore, but then I'm using it for every signal sent. This may
cause issues. For example, if train A passes the light sensor and is suppose to
stop, but train B has 'grabbed' the transmission via semaphore (or even queue,
then train A will proceed merrily past the light sensor until the queue gets to
stopping it or the semaphore is released. By then the train could be way down
the track.
Though, workign with the microseconds in programming language vs. the seconds of
travel, that may not lead to much.
I'll give it a shot.
Thanks, Christopher.
