Two MBTA Green Line trolleys collided Friday evening, shutting down service on a section of the B branch and traffic on Commonwealth Avenue.

The MBTA reported 25 people were injured and taken to local hospitals. The Boston Fire Department said as of Friday evening, none of the injuries were considered life-threatening.

"The safety and well-being of our riders and employees is our chief priority. We take this matter extremely seriously and are actively investigating the incident to understand what occurred, and prevent it from happening again," MBTA said on Twitter.

As of Saturday morning, train service was restored between Kenmore and Washington Street and shuttle buses phased out.

One of the Green Line operators involved in Friday evening’s collision has been placed on administrative leave, according to information released Saturday by the MBTA. That employee — who has worked with the authority for seven years — was operating the trolley that struck the other trolley from behind.

"The other streetcar operators have not been placed on leave," the MBTA said.

Photos from the city's fire department showed a smashed windshield and substantially dented trolley car.

The collision occurred across from Boston University’s Agganis Arena. The MBTA suspended service between Packard's Corner and Kenmore. Westbound car traffic was also prohibited, but reopened Friday night according to an alert sent by Boston University.
