MBTA officials said investigators are interviewing an Orange Line train operator after a man was injured when he stepped off a train that had stopped just outside the Roxbury Crossing station on Wednesday.
Train doors opened on the platform side even though the train had not fully reached the station around 3:45 p.m., the MBTA said. The train did not move while the doors were open, the agency said.
Officials said they are investigating what caused the door to open but have ruled out an issue with the train itself or a mechanical problem. It is not clear why the train stopped short.
Two people got off the train as it sat in place, the MBTA said. That section of track is outdoors.
An MBTA spokesperson said they did not fall out but exited on their own.
One man was taken to a local hospital with minor injuries, officials said.
“The train door opens and an adult male intentionally steps/jumps off the train,” said Richard Sullivan, superintendent of the MBTA Transit Police.
The second person who got off the train was not injured, according to the MBTA.
One passenger, Dioni Acosta, 14, said he saw the man on the ground lying “motionless.” He did not see him get off the train.
The man was not trapped beneath the train and did not require a technical rescue, Sullivan said.
According to a Globe reporter who was on the train, it was stopped for about an hour before proceeding to Roxbury Crossing, where the remaining passengers got off. The train was then sent to Wellington Yard for inspection, the MBTA said.
The Globe reporter estimated the drop from the doors to the ground was about five feet.
Orange Line service was paused during the incident. Trains were back in service by about 5:15 p.m., according to an MBTA alert.
