Shuttle buses will replace a stretch of Orange Line train service for the next three weeks while MBTA crews replace a track switch damaged during a Tuesday derailment, and all new trains on the Orange and Red Lines will be taken out of service for an investigation, the T announced.
Buses will continue to run between Oak Grove and Sullivan Square stations for three more weeks while workers replace the decades-old switch. The T described the switch as "significantly damaged" due to the slow-speed derailment at Wellington Station.
