I used a pair of "Z Stuff" IR detectors and a relay to power flashers at a crossing on our modular layout. They are a little out of scale but work great. They detect the physical presence of a train so no wiring of blocks is required. This is ideal in a modular layout where the flashers need to start operating a few feet before the train gets there. I can never be sure exactly which module precedes the one with the flasher so block wiring was not desirable in that application.
Minus: 1) Not to scale 2) They won't scan across both tracks of the dual mainline so we became direction sensitive. Trains had to run right handed. I mean to check with Z stuff to find out if we can add 2 more detectors to avoid direction sensitivity. Plus: This taught me how well IR detectors work. I have seen plans to make them and bury them in the track. This would be the ideal way to go for IR.
