What is an Emergency Notification System Sign?

What does an emergency notification system sign look like?

The Emergency Notification System sign, commonly called the ENS sign, is a blue and white sign posted at or near a highway-rail grade crossing. It displays two critical pieces of information: the railroad’s emergency phone number and the crossing’s unique US DOT identification number. Every highway-rail grade crossing in the United States is required to have one, so knowing how to spot it before you ever need it could make all the difference in an emergency.

Why ENS Awareness Matters in Our Communities

Every June, California Operation Lifesaver joins rail safety advocates across the country in observing ENS Awareness Day, a reminder that this small blue and white sign plays a major role in preventing tragedies at highway-rail grade crossings. Most people pass these signs every day without knowing what they are or how to use them. By learning to locate the ENS sign at crossings in your community and sharing that knowledge with others, you become part of a statewide effort to keep California’s roads and rails safer for everyone. Watch the PSA above to see exactly what to look for, then share it with someone you care about.

What to do if you’re stuck on the tracks

If your vehicle stalls or becomes trapped on railroad tracks, acting quickly is essential. Watch the video below so you know what to do in case of an emergency.

  • Locate the blue and white sign and dial the railroad’s emergency number listed on it
  • Give the dispatcher the US DOT crossing number so they can immediately alert train operators in the area.
  • If you cannot find the ENS sign or if the number is damaged, call 911 right away.

Most importantly, get yourself and any passengers away from the vehicle and off the tracks, move at an angle away from the crossing in the direction the train is coming from, so you are not struck by debris.

Knowing what to do at a highway-rail grade crossing goes beyond the ENS sign. From warning signs to flashing lights and gates, California’s roads and rail corridors are full of important signals designed to keep you safe, but only if you know what they mean.
