Two riders were safely evacuated from a Blue Line train that was stopped Friday morning between the Bowdoin and Government Center stations when wires came down across the tracks, officials said.

"Some wires came down in the tunnel. They were smoldering," said Boston Fire Department spokesman Steve MacDonald. "The wires were across the tracks, and when the MBTA cut the power, the smoldering stopped."

MassDOT spokesman Mike Verseckes said the train stopped around 9:40 a.m. due to a "vehicle and signal issue."

Buses replaced service between the Bowdoin and Airport stations, Verseckes said. At 12:40 p.m., the MBTA reported that service was resuming with moderate residual delays.
