BOSTON — The MBTA on Tuesday morning announced it has pulled all of its new Orange Line trains out of service.
"Inspectors identified a fault with the bolsters which is being corrected to ensure the vehicles are reliable & safe for the duration of their service lives," the transit authority tweeted. "We expect to return them to service later this week."
It’s the latest setback for the T, which has long been beset by service and maintenance problems and budget deficits, and the latest problem to surface with the new train sets.

Last August, the MBTA began introducing new Orange Line trains, part of a larger plan to roll out 152 new cars to completely replace and expand a fleet that at the time was comprised of 120 cars.
T officials didn't say how many trains were pulled from service on Tuesday; a spokeswoman was unavailable to offer additional specifics about the problem or impacts on service.
The Massachusetts House plans to debate legislation Wednesday raising taxes and fees, in part to improve the MBTA.
