Flashing lights at the platform's granite edge will alert you that a train is entering the station. Identifying The Train Check the destination of the train before you board. If you're taking the orange, blue, yellow or green line, destinations are displayed over the train's front and side windows. Boarding The Train Stand clear of the train car doors and let passengers get off before you board. Be sure to step over the gap between the platform and the train.
Chimes signal that the car doors are closing.
Once the chimes have sounded, step back and wait for the next train. Unlike elevator doors, the train doors do not reopen automatically. See the station manager at the kiosk. In emergencies, you can press the red button on the callbox located on some of the station's pylons. Farecards are not refundable, but exchanges will be made for malfunctioning farecards.
