I got stuck in that this morning. The train I was on was just about to enter the 42 street station when he fell. So of course, they stopped the train in the tunnel, and then cut the power, which turned off the A/C - at least it didn't turn off all the lighting - and we sat there for more than half an hour before they finally started moving the train.
I feel sorry for whomever it was; may he rest in peace.
