The Boston Fire Department extinguished an electrical fire on a commuter rail train parked in an MBTA maintenance yard near Widett Circle in South Boston Wednesday evening, officials said.
Nobody was on the train or performing maintenance on it at the time of the fire, said Brian Alkins, a spokesman for the Boston Fire Department
The fire began at about 5:10 p.m., Alkins said.
He described the fire as an “electrical fire in the internal space in the engine” of the train. The fire was on top of the train, so somebody must have seen it from above, he said.
Workers shut off power to the train, and firefighters climbed onto it and used dry chemicals to put the fire out, Alkins said.
Keolis, the private company that runs the commuter rail, services rail cars at its Southampton Street Yard.
A spokesman for the company confirmed the train car was undergoing maintenance.
“The locomotive was not in service as it was undergoing maintenance,” Tory Mazzola said in an e-mail. “We do not expect this incident to impact service tomorrow morning for our commuter rail passengers.”
