MTH PRR signal bridge - making it work like a real 3-position signal

PennsyloverOGR Forum Member

Has anyone reworked the MTH PRR position light signal bridge so that the diagonal/approach indication (equivalent to a yellow signal) is driven by track occupancy instead of a timer? Did you completely strip out the current wiring and rewire it from scratch, or was only a minor modification needed?
