Orange Line train at Back Bay is stuck; at least passengers are calm, not amok

One of the new Orange Line trains is just sitting at Back Bay, immobile, with passengers wishing it could get up and go already so they can get home. Josh Levinger tweets at the T, which replies, it knows, oh, Lord it knows, or more specifically:

Hi Josh, this train is experiencing a mechanical issue. Orange Line supervisors are on scene working to overcome the issue.

Levinger adds:

Operator just came by and said "we’re having a little train problem, guys." He’s doing his job, and to be clear I’m not actually worried about my safety. But, I would like to go home.

Meanwhile, Levinger's wife, Ruth, says hubby's name is very much not Charlie, so she'd rather not have to head down to the station at a quarter past two to hand him a sandwich as the train comes rumbling through, um, just sits there:

Let my husband go.

UPDATE: Levinger reports some good news: No, the train isn't moving. But he found a scratchie.

UPDATE UPDATE: Levinger reports that, after 25 minutes, hard-working T employees got the doors open to let passengers out, at least.
