Safety & security

It's important that we all work together to stay safe and sound.

Train safety

Stay safe around Link and Sounder trains

Look, listen & live

  • Be alert - it's difficult to judge train distance and speed.
  • Look both ways - trains may come from either direction.
  • Listen for train horns and bells.
  • Don't use cell phones. Do remove ear buds.

Tracks are for trains

  • Don't walk, bike, skateboard, jog or play around tracks.
  • Don't take shortcuts across the tracks.
  • Don't lean over railings. Trains can overhang tracks by three feet.
  • Don't walk near a parked train. It may move without warning.


  • Don't wait on tracks if stuck in traffic.
  • Truck drivers - don't commit if you can't fit safely across the tracks.
  • Obey all signs and signals.


Always use crosswalks and obey all traffic signs, signals and crossing gates

  • Trains always have the right of way.
  • Never walk around or under rail crossing gates.

On the platform

  • Hold small children by the hand while on the platform.
  • Stay behind warning strips at the edge of station platforms.

Bus safety

Stay safe around ST Express buses

  • Never try to board or exit a moving bus.
  • Buses won't stop once they leave a bus stop.
  • Let other passengers leave the bus before you board.
  • Keep aisles clear of packages and personal items.
  • As you leave the bus, watch for other motor vehicles.
  • Wait for the bus to pull away before crossing street.
  • Wait only at designated bus stops.
  • Do not try to hail a bus from a place that is not a designated stop.
  • Do not run after a moving bus.

See something, say something

Fare Enforcement Officers

Fare Enforcement Officers

You will see Sound Transit fare enforcement officers walking through our trains and facilities. If you have questions about service, schedules or fares or if you have safety concerns, our fare enforcement officers are available to help. Fare enforcement officers are also on board to check tickets and ORCA cards, so before you enter a Sounder train or a Link platform, please be sure to tap your ORCA card or have a valid ticket. You may get a fine if you do not pay for your ride.
