Service on MBTA Red Line trains was partially suspended due to police activity at Andrew Station Friday, the agency said. Shuttle buses replaced trains between Park Street and JFK/UMass for about an hour starting about 12:30 p.m.

Following an extensive investigation, MBTA officials now say a broken axle is to blame for a derailment on the Red Line back in June.

Boston Mayor Marty Walsh is among the critics demanding the MBTA delay a planned fare hike following two recent derailments that continue to cause delays on the Red Line.

Following two recent derailments, Boston Mayor Marty Walsh and many commuters are expressing their frustration with the upcoming MBTA fare hikes. The MBTA, however, is not backing down.
