The MBTA's new higher-frequency schedule for the Fairmount Line took effect yesterday, May 20, which means that riders in Roxbury, Dorchester, Mattapan, and Hyde Park can now catch a train every 30 minutes on weekdays.
The new schedule also gives weekend riders a considerable boost in service: while the previous schedule had trains running every 90 minutes, the new schedule has trains running every 30 to 60 minutes.
