UPDATE: Braintree Red Line Service Delayed, But Running

This story was updated at 3:58 p.m. on Thursday, Jan. 26.

BRAINTREE, MA — A rollover crash on Route 93 in Boston altered Red Line service on the Braintree line Thursday afternoon. However, MBTA officials announced that the service is now operating fully, albeit with delays.

"Delays of about 20 minutes after an earlier accident blocking service between JFK/UMass and North Quincy. Service is proceeding," MBTA officials said.

Earlier, riders on the Braintree line needed to pivot to shuttle services, or the commuter rail.

"Shuttle buses replacing service between JFK/UMass and North Quincy due to service being blocked. Please expect delays as shuttles are dispatched," officials said.

MBTA officials said the Commuter Rail will also accommodate customers between Braintree and South Station in both directions.

Middleborough and Kingston trains will stop at Braintree, Quincy Center and JFK. Greenbush trains will stop at Quincy Center and JFK, officials said.

The MBTA police shared a photo and additional information on what's causing the issue. According to them, the overturned trailer damaged fencing, which is causing interference on the train line.

Massachusetts State Police officials said troopers are on the scene in the Savin Hill area of Boston, which is where the tractor-trailer rollover crash happened.

"At this time only the left lane is open. Expect significant delays," officials said.
