I use ITAD's on my layout. They work well but I am using 2 ITADs per crossing signal and the crossing gates do not work correctly when set up with 2 ITAD's. The issue being that when one ITAD is activated it sends the signal for the crossing gates to go down while the other ITAD (which has not been activated yet) is still sending the signal for the crossing gates to stay up. so the crossing gate will not lower until both ITADs have been activated. It took me a bit to figure out what was going on. I built a small relay board to connect in line with the activation wires that eliminated this issue
