BOSTON — Keolis Commuter Services, operator of Massachusetts Bay Transportation Authority commuter trains, says it is investigating a Tuesday incident in which a packed train operated with one coach door open.
WHDH-TV reports that a commuter on the Middleboro-bound train from Boston’s South Station tweeted that “there were people holding on for their life … so they didn’t fall out of the train” and said one passenger held the door closed while the train was moving, but he would occasionally lose his grip and the door would reopen.
A commuter rail Twitter account responded, “We’ve escalated this concern to be addressed as safety is very important to us. Sorry for the uncomfortable commute.”
