The Red Line outbound is dead at Andrew Square due to what the T is calling a "power problem" - dead enough to try to get shuttle buses running between Park Street and Ashmont.
Thomas reports he was on the last car of a train around 11 p.m.:
We were evacuated in a hurry by an official who said the train was on fire, then corrected himself by saying there was a fire in front of the train.
Frank Severino reported "smouldering electrical equipment on tracks" between Andrew and JFK/UMass. Firefighters were using chemicals to fight the fire until the T could shut down power so that they could use water.
The T reports the smoke came from fire in a manhole just south of Andrew station - which heavily damaged five cables powering the Red Line. Once firefighters doused the fire, T workers began repairs to the power lines.
