Oddjob60 provides the latest proof that T drivers and conductors just aren't going to stop the train to see why the doors aren't closing properly, with a report from Red Line car 01625 at Charles/MGH around 7:30 this morning:

... As people went out the doors, even before anyone tried getting on, the doors closed. People inside and outside put their arms in the way, and even tried to force the doors open, which should have sent some kind of signal to the conductor so she (I looked later, it was a she) would reopen the doors, right. Nope. Not even one of those "please don't block the doors" announcements. People finally gave up, the doors closed,and off we went. At least 10 people on my car had to get off at Kendall so they could ride back to Charles. ...

A fire broke out under the tracks at Charles/MGH station on the Red Line at around 8pm this evening. As of 9:20pm, the second alarm has been called in, the third rail shut down, trains near the station evacuated and shuttle bus service has begun.

Expect disruptions to last through the end of service on 5/1.

EDIT: Red Line service was restored at 10:49pm.
