Firefighters are on Elm Street in Dorchester, trying to contain any fluids that might be leaking from a T maintenance vehicle that fell off the Red Line around 7 p.m.
A T spokesman reports:
A piece of equipment crews have been using all weekend for track work on the Dorchester branch of the Red Line slid down a hill today. Operator of the equipment had no visible injuries but was taken to the hospital as a precaution. The cause of the accident is under investigation. Buses have been replacing train service in that area all weekend to allow crews to perform the track work.
