UPDATE: Now there are problems on the Orange Line, where somebody managed to get his foot stuck between a train and the platform at North Station.
It's Dead Train Day on the Red Line. And it's so bad, the MBTA has broken out a rare "severe" delay warning.
Among those affected: Alexandra Elizabeth, who sent out a tweet for help around 8:30:
Hoooray. The MBTA train I'm on to Harvard has, of course, broken down. I'm in a tunnel with a bunch of strangers. Get. Me. Out.
Meanwhile, at the other end, a truck crashed into a traffic light right outside Broadway station.
