The MBTA says service has been suspended on part of the Green Line after two trains collided in Boston Wednesday.
The crash happened near Government Center and caused a service interruption, initially between Park Street and Somerville's Union Square. Train service was later restored between Union Square and Lechmere in Cambridge, the MBTA tweeted shortly before midnight.
There were 20 to 25 passengers on one of the trains, none of whom were hurt, according to the MBTA. The other was not carrying any passengers.
Three Green Line operators were taken to Massachusetts General Hospital with unspecified injuries, the MBTA told NBC10 Boston.
Both of the trains were derailed in the collision.
The MBTA said shuttle service would be available between North Station and Lechmere in Cambridge. People were advised to use the Orange Line for service in Downtown Boston.
Additionally, Blue Line trains are bypassing Government Center in both directions, the MBTA said.
