Fire on the inbound tracks between Arlington and Copley around 7:40, Jay Joynes tweets. At first, the T shut Arlington station because of heavy smoke, but shortly after 8 a.m., it shut down all Green Line service downtown. And shortly after 8:30, the T began evacuating trolleys stuck in the tunnel near Hynes and Copley stations.

The T eventually sent in some shuttle buses between stations to the west and downtown, but many commuters didn't wait. As Gracetopia tweets:

I now feel like one of the army of the commute, as I walk from Kenmore to downtown with my fellow MBTA refugees.

Lindsay Douglas, though, was one of the people who stayed behind at Kenmore:

I've never seen chaos like this. Coldest day of the year + the MBTA shuts down the green line. Yelling+angry people.

And because misery loves company, an inbound Red Line train died not long after at Charles/MGH, Rob Grover tweets. Later, another train died at Porter. Around 9:20, another train died, inbound at Andrew.

The Wandering Jew reports he isn't wandering all that much on the Green Line this morning:

This T driver is giving me whiplash. Impressive given how slowly we're going.

Joy. Alarms going off on the T. Driver using the emergency brake/door release to let passengers off.

Passengers on board urging the T to move with encouraging chants of "come on, come on" and "you can do it..."

I am not chanting encouragements. I'm muttering curses.

UPDATE: A second Red Line train died at Alewife; another Green Line trolley gave up the ghost, bollxing up outbound C and E service. Commuter rail? You don't want to know.

In this young year, the Red Line is now 2 for 2 in morning-commute delays due to dead trains, this time at JFK/UMass, but today has the extra bonus of delays due to "weather-related issues."

Meghan C. reports it took her 75 minutes to get from Braintree to MGH.

The T is busing Riverside riders between Reservoir and Riverside because of a tree that fell on the tracks.

WBZ interviews the driver of the trolley that was stopped at Boylston when another train plowed into his on Nov. 29. The other driver, coming off an eight-hour overnight shift at another job, was fired.

MBTA Transit Police report arresting John Wintersteiner, 30, of Newton, on charges he masturbated at the Beaconsfield Green Line stop earlier this month to the shock of a woman on the other side of the tracks.

Wintersteiner, whom police said was dimed out via the T's anonymous tip line, will be arraigned in Brookline District Court today on a charge of open and gross lewdness, following his arrest at his home this morning.

Innocent, etc.

MBTA Transit Police have posted a photo of a guy they say bashed the bishop at Beaconsfield on the evening of Dec. 3 while a woman looked on in shock from the other side of the tracks.

Matthew provides notes from last evening's meeting on the need for a new Government Center T stop and how officials are planning to move people around when they lose the connection between the Blue and Green lines for two years.
