Improvement on the Orange Line: Train dies above ground with a bang, but it doesn't catch fire and nobody feels the need to jump off a bridge

Tim Sullivan was on one of the new Orange Line trains when it pulled out of Community College, made a couple of loud banging sounds and then died on the flyover towards Sullivan Square, shortly before 7 p.m. He reports on the wait and eventual evacuation:

We heard two loud metal bangs coming out of CC before entering the flyover and then we lost power on the incline. There were two shop guys on our car that just happened to be "catching a ride" who were immediately concerned. They are aiding with the diagnosis.

Communication from the operator of 1414 (the dead train we're on) has been EXCELLENT. Frequent updates.

"We have a missing shoe on the head car."

"The 3rd rail is uneven and one side is higher than the other and knocking shoes off. 600 feet outside the NS portal."

Finally, about an hour after they clanked to a halt, T workers evacuated passengers:

We are evacuating into the ROW at the Sullivan flyover.

Evac of 1414 lead has begun.

We've all made it safely to Sullivan.

As of 9 p.m., the T was still doing bustitution between Back Bay and Wellington due to what it called "a power problem."
