Last train out of Paris, um, the train to the Pats' game

Who'd think a train to the Patriots game could cause so much trouble? But let's follow the tweets:

At 4:40, Jon Fournier tweets from Back Bay:

Stuck behind Patriots train. Chaos at Back Bay. Lv it to T to make smthng so simple so freakin' complicated.

At 5:11, Fournier gets out this word:

Herd of patriots fans boards Franklin train in Dedham. Told to get off at Walpole & "wait for train."

At 5:21, Ben Jackson explains:
