‘Uncommon Noise’ Pulls New Orange Line Trains From Service, Again – StreetsblogMASS
The MBTA’s new Orange Line trains, which debuted this summer, have been taken out of service indefinitely while engineers investigate an “uncommon noise” coming from the underside of the new trains.
“With safety as a top priority and out of an abundance of caution, the decision was made to temporarily remove the new cars from service to investigate the issue, any potential impacts, and deploy a fix, if needed,” wrote Battison in an email message Monday morning. “We anticipate the issue to be resolved soon with the cars back in service following this investigation, which is currently taking place.”
According to newtrains.today, a website that monitors data from the MBTA’s real-time vehicle location service, the new Orange Line vehicles haven’t been in service since November 18, the same day that one of the new trains had gone off the rails in the Orange Line’s maintenance and storage facility in Medford:
Earlier today in the Wellington Yard, the last car of a new Orange Line train came off the rails while traveling at a low speed over a track switch. The car has since been re-railed and our initial reports show no significant damage to the train.

The new trains also had another extended hiatus from service earlier this fall, when MBTA engineers were forced to fix a glitch that caused its doors to unexpectedly open while the trains were in motion.
The MTBA celebrated the debut of its first new Orange Line train in August, and a second train entered service in September.
Since then, though, the rollout of new trains has stalled, with no new trains entering service in October or November.
Under the Orange Line’s new vehicle procurement program, the MBTA expects to take delivery of 152 new Orange Line cars before the end of 2021. On that schedule, new 6-car trains should be entering service roughly every month for the next 24 months.
