Yesterday morning, before we had managed to travel a full stop, our subway train stopped with an announcement that somebody was injured on the tracks. The power was shut down (auxiliary lights came on) and we sat still for 27 minutes. It wasn't that bad, just strange; even when trains are stopped, there's usually a hum of speakers and paused engines. It's rarely that truly quiet.
The conductor herded us up the length of the train to a car that was in the station and we were then free either to wait for the situation to be resolved (if, you know, you had a spare few hours) or to exit the station and make our way as best we could. This led to my favorite snippet of dialogue from the day:
Cop to querulous member of public: Do you have to wait for the train? No, you can do something else.
