A pedestrian was struck and killed by an MBTA commuter rail train in Gloucester early Thursday morning, authorities said.
Transit police said in a statement that a man whose age is unknown was on the train's right of way in Gloucester when he was struck by an inbound train just before 6:20 a.m. The man was pronounced dead following the incident.
Authorities continue to investigate but said they do not suspect foul play.
The incident created major service disruptions along commuter rail lines north of Boston during the morning rush. Several inbound and outbound trains on the Lowell, Fitchburg and Rockport lines were canceled, and other lines saw delays in both directions.
One Rockport train ran with delays of up to 55 minutes, the service said, and shuttle buses were used between Rockport and West Gloucester.
A spokesman for Keolis, which operates the commuter rail, said around 10:15 a.m. that the impacted section of track had reopened to train traffic but that residual delays may occur on the Newburyport/Rockport line.
The incident was the second this week in which a pedestrian was struck and killed by a commuter rail train. A man transit police said was about 21 years old was hit by an inbound Fitchburg line train in Belmont around 6:20 a.m. Monday morning.
