Weekend Green Line collision sends 5 to hospital

A Green Line train crashed into an out-of-service stationary train Sunday morning, sending one passenger and four operators to nearby hospitals.

The moving train was carrying five passengers and struck the stationary train at East Somerville Station just before 12:30 a.m.

"The MBTA apologizes to Green Line customers who are impacted by the disruption in service, following a late night incident involving two trains," MBTA spokesman Joe Pesaturo said in a statement.

Pesaturo said shuttle buses were available between North Station and Medford/Tufts Station "while the NTSB responds and begins its investigation." Buses continued to replace service until about 10 a.m. Monday morning, the agency said in a post on social media.

The passenger transported to Mass. General Hospital reported a neck injury. The T said that "all four" Green Line operators were transported to a hospital and were conscious and alert.

One car on each of the two-car trains derailed, the T said. Responders included MBTA personnel, Transit Police, Somerville Police, Somerville Fire/EMS and the Department of Public Utilities. The Federal Transit Administration was notified of the incident.
