BOSTON (WHDH) – The Fairmount Commuter Rail Line was shut down for about 18 hours after an official says “human error” likely caused an out-of-service train to strike another train just outside of South Station Tuesday night.
The low-speed incident, which occurred around 8 p.m., left three coach cars derailed, according to an MBTA spokesman.
