PSA: Welp, I never knew about this. Recently there was a fatal accident in Peco, Texas, with a truck stalled on a railroad crossing & a freight train hitting it at track speed. Save lives: If stalled on tracks--find the blue sign & call the number FIRST! "The Emergency Notification Systems (ENS) sign gives the public critical emergency contact information at every highway-rail grade crossing. The information on the ENS sign enables the public to reach the railroad responsible for the crossing."
