The National Transportation Safety Board's (NTSB) investigation of last week's collision of two Massachusetts Bay Transportation Authority (MBTA) light-rail trains continues as investigators gather information and evidence, according to an NTSB update.
On July 30, a westbound MBTA Green Line train collided with the rear of a MBTA Green Line train that was also heading westbound on the track ahead.
As a result of the collision, two cars on the leading train and one car on the trailing train derailed. Twenty-seven people, including MBTA personnel, were transported to a hospital with non-life threatening injuries.
Investigators secured data from the event recorder from the operating car of the striking train. A preliminary review indicated the train that was hit was traveling at about 10 mph, NTSB officials said in a news release.
The striking train overtook the other train while traveling at about 30 mph.
