4 Workers Hurt when Boston Subway Trains Collide

BOSTON (AP) — The Boston subway system continued to experience service disruptions on Thursday morning following a crash Wednesday night that sent four employees to the hospital, officials said.

Both Green Line trains derailed in the crash at about 9:20 p.m. Wednesday.

A two-car, westbound train, with 20 to 25 passengers on board struck a two-car train without passengers as it was preparing to enter service at Government Center Station, a Massachusetts Bay Transportation Authority spokesperson said.

Four operators were taken to Massachusetts General Hospital and one was released Thursday morning. The nature of their injuries was not disclosed.

No passengers were treated for injuries, the spokesperson said. One train has since been placed back on the tracks.

The cause is under investigation.

The track infrastructure will be inspected and if repair work is necessary, it will take place before service resumes.

The collision comes amid a federal review of the MBTA’s safety following several accidents that led to injuries or death.

A 39-year-old man died in April when he was dragged after his arm got stuck in a malfunctioning subway car door. Nine people were injured in September when an escalator at a station malfunctioned, and more than two dozen went to the hospital last July when a Green Line train rear-ended another trolley.
