Boston firefighters extricated a man who became trapped underneath an MBTA Red Line train at the Fields Corner station, leading the T to deploy shuttle buses on the Ashmont line for about an hour on Friday.
Full service was restored around 9 a.m., officials said.
The incident began around 8 a.m. Friday, and firefighters successfully removed the middle-aged man around 8:30 a.m. He was injured, but conscious and alert, officials said.
Teresa Harris was at the station when the incident took place. “I heard the screech and I heard a couple of ladies scream,’’ she said later.
First responders, including Transit Police officers, were talking to the man and inquiring whether he was current with his medications, she said.
Transit Police Superintendent Richard Sullivan said the incident is not being investigated as a crime, but a trespassing incident. The investigation is ongoing.
Shuttle buses were used between Fields Corner and the JFK/UMass station in Dorchester, the T said.John R. Ellement can be reached at email@example.com. Follow him on Twitter @JREbosglobe.Katie Johnston can be reached at firstname.lastname@example.org. Follow her on Twitter @ktkjohnston.
