Does anybody know when weekend service disruptions on the Red Line between North Quincy and JFK/UMass will end? It seems like it's been happening a lot this summer. Currently, the MBTA web site shows that buses will replace the trains for two weekends in August. Is this part of a larger project that will have a definite end date, or just business as usual for the Red Line? I am relatively new to the area, so not sure what to expect. Thanks!
