Around last month, or so, I was going back home from school. So as soon as I got to the Main St station, MTA workers just closed the station, and told me that the (7) line was temporarily shut down.
(since all (7) trains are currently pure R62A's, i'm only mentioning (7) for this)
So ok, there was a shuttle bus that made up for the (7) service.
They were announcing that there had been a passenger accident in 90th st, thus, a police investigation.
As soon as the bus reached junction blvd, they announced that (7) service was resuming. So I decided to get on the (7) just to see what exactly happened. Yes, the manhattan bound (7) was forced to run on the express track.
Once the train nearly approached 90th st, there was a (7) that was stopped in the middle of the station (on the manhattan bound track), and the front car had the storm door open. A little further, and there were about 10 cops, and apparently, they had a dead person's body on a stretcher (was covered in a white sheet).
EDIT: found a link that reports this incident
