As of 7:00, my 6:30 train is still held up. Conductors are still just saying they're waiting for a hold signal to end. The doors keep closing as if we're about to go, then they open back up a few minutes later and we keep sitting here. Other trains on my line aren't getting track numbers or arrive and also get held

Edit: A few minutes after posting this and we're finally moving. Conductor announced that the delay was due to a "trespasser in the tunnel here."
