BOSTON (WHDH) - An MBTA operator facing charges in connection with a Green Line crash that left more than two dozen people injured faced a judge Wednesday.

Owen Turner was arraigned in Brighton District Court, where he pleaded not guilty to two counts of gross negligence.

Prosecutors say the 50-year-old Mattapan resident was operating a Green Line trolley three times the speed limit on July 30 when the trolley plowed into the back of another trolley that was moving the speed limit on the B Line near the Agganis Arena.

They added that Turner did not apply the brakes of the trolley prior to the collision.

Twenty-four passengers and three crew members were hospitalized with non-life-threatening injuries.

Turner first told transit police that he had no memory of the crash but the next day he claimed he fell asleep, according to prosecutors.

“The defendant told transit police that he’s known amongst colleagues as a fast operator and that he gets frustrated by someone who drives ahead of him,” prosecutors said in court.

Turner was hired by the MBTA in 2014 and has been suspended on six different occasions.

In 2020 alone, he was cited three times, including in April of last year when investigators say he was operating a trolley at 43 miles per hour in a 25 miles per hour zone.

The T is now taking steps to fire Turner.

Turner was released on personal recognizance under the conditions that he only drives during daylight hours to take care of family business.

His next court appearance is scheduled for December.
