A blue sign showing railroad emergency number and DOT crossing number

What is an emergency notification system sign?

An Emergency Notification System (ENS) sign, posted at or near a highway-rail grade crossing, lists a telephone number along with the crossing's US DOT number and is used to notify the railroad of an emergency or warning device malfunction. 

Our "Find the Blue and White ENS Sign" PSA shows you what to do if you're stuck on the crossing.

Do you know what to do if you're stuck on the railroad tracks? Watch our PSA to save your life.

Quick Tips

  • Trains and cars don't mix.
  • The train you see is closer and faster-moving than you think. 
  • Be aware that trains cannot stop quickly.
  • Never drive around lowered gates — it's illegal and dangerous. 
  • Do not get trapped on the tracks; proceed through a highway-rail grade crossing only if you are sure you can completely clear the crossing without stopping. 
  • If your vehicle ever stalls on the tracks, get out and get away from the tracks, even if you do not see a train. Locate the Emergency Notification System sign and call the number provided, telling them about the stalled vehicle. 
  • At a multiple track crossing waiting for a train to pass, watch out for a second train on the other tracks, approaching from either direction.
  • When you need to cross train tracks, go to a designated crossing, look both ways, and cross the tracks quickly, without stopping. Remember it isn't safe to stop closer than 15 feet from a rail.
  • ALWAYS EXPECT A TRAIN! Freight trains do not follow set schedules.
