On the Braintree branch of the Red Line, however, a disabled train between JFK/UMass and North Quincy stations caused 20-minute delays from about 8:40 to 9:15 a.m., according to the MBTA’s X feed.
After more than a year of track work across the MBTA system, the final long-term speed restrictions were removed when a section of the Green Line reopened on Saturday.
