Winter comes to Boston and the Red Line struggles

At 7:28 a.m., Mike Connor tweeted:

It's officially snowing in Boston. Snow is blowing into the red line car "standing by for a moment" at MGH.

A train died on the Red Line this morning, of course, this time at Alewife. Also, the T reports issues on the Red Line and some commuter lines with slippery rail, caused not by the snow but by the pulpy, soaky remains of millions of dead leaves that just don't stop falling on the tracks.
