May I have your attention please!(71)We are experiencing delays on all trains on the green line.(72)There is a power outage near the Harding station. A tree has fallen across some electrical wires. Our utility crews are on the scene, but we are not sure how long it will take to restore power. If you are waiting on platforms 3 and 4, we encourage you to come back in to the station as we will not be boarding any trains on the blue line for at least half an hour.(73)We will update you again in 15 minutes.
