A. Wells. /No I did not, I’ll go check out your post. My thought is to have the sensor, say 3 feet away from crossing on both sides , and trigger lights and gates to the approaching train, and clear when other sensor detects the train has pasted. Returning gate up and stopping the flashing lights. I also thought of placing a flashing amber light as the default state, then I know the circuit is working. I’ve seen European crossings with a slow flashing amber light when crossing is clear and moves to flashing red when a train is approaching. I know not prototypical for US crossings, but it’s cool to see the crossing always active.
