Commuter rail service on Fairmount Line, which was replaced by shuttle bus service today due to an incident last night, has been fully restored this afternoon. A spokesperson for Keolis Commuter Services, the company operating and maintaining the commuter rail systems, says that repairs and inspections allowed for full service to resume around 2 p.m. today. Passengers are advised to follow @MBTA_CR on Twitter and subscribe to T-Alerts for real-time updates.
Multiple trains on the Fairmount Line were cancelled today following the incident, which involved an out-of-service train departing a maintenance facility and an inbound Fairmount Line train entering South Station.
While MBTA and Keolis are still investigating the incident, initial findings indicate human error as a likely cause for the incident, according to an MBTA statement.
