This just in from the T: The first ever air-conditioned Mattapan trolley rolls out of Ashmont station at 2 p.m. today. The other nine trolleys on the cutest transit line in all of Massachusetts will be retro-fitted with A/C by the end of the summer.

That big thunderstorm this morning pushed a tree branch through the windshield of a Mattapan trolley, injuring the driver and two passengers.

(Thanks to CharlieBlog for noticing this story on Channel 7's website.)

If somebody ever made a model-train layout of the Mattapan Line, one of the stops would look just like this.
