MBTA officials say they are still probing the actions of the operator of a Green Line trolley that crashed Monday, while they have generally ruled out problems with the tracks, signals, and the trolley involved.
“Investigators continue to take a close look at the performance of the motorperson who was operating the train at the time,” MBTA spokesman Joe Pesaturo said in a statement.
Pesaturo said an inspection of the track and signal systems had found no “defects or anomalies” and preliminary testing had found no “mechanical issues” with the trolley.
MBTA Transit Police are investigating, officials said.
Pesaturo said the trolley driver, who has worked at the MBTA for four years, has been “removed from service” during the investigation.
The crash, which happened at the intersection of the D and C branches, sent seven people to area hospitals, officials said. Many of the victims had back injuries.
Crews worked through the night to restore service, officials said.
The derailed car, the first of a two-car D Line trolley bound for Riverside, veered off the tracks between Kenmore and Fenway stations about 12:20 p.m. Monday.
The first car of the train crashed into the tunnel wall, officials said.Martin Finucane of the Globe staff contributed to this report. Martine Powers can be reached at email@example.com.
