I'm making a route and i got inspired by this video.

How to make the traffic lights and signals go red once train hits the trigger? I know how to make the crossing with ATLS. But i don't know how to make it with Traffic lights.

Don't reply i already made it myself. All i had to do add 1 route and set traffic lights main to 1 route and set controller SPL red and phases green
