Passengers on the Newburyport/Rockport lines of the MBTA commuter rail were facing significant delays Thursday morning after a person was struck and killed by a train in Gloucester, officials said.

Transit Police officers received the radio call at approximately 6:20 a.m., and Gloucester firefighters and EMS also responded to the scene.

“A male, age unknown at this time, while trespassing on the right of way was struck by an inbound commuter rail train,” Transit Police said in a statement. “The male has been pronounced deceased as a result of injuries sustained.”

Transit Police said the incident is under investigation.


“As a result of this police activity, we expect delays on the Newburyport/Rockport lines this morning,” said Tory Mazzola, a spokesman for Keolis, which operates the commuter rail for the T. “Passengers should stay connected to MBTA.com and @MBTA_CR on Twitter for updates.”

According to the MBTA Alerts webpage, Rockport trains 102 (5:48 a.m. from Rockport) and 104 (6:30 a.m. from Rockport) were cancelled due to the “severe service disruption” in Gloucester preventing the movement of trains.

Shuttle buses were being provided between Rockport and West Gloucester, and officials said Rockport line passengers should expect “significant delays” in both directions.

The Haverhill, Lowell and Fitchburg lines may also experience delays, officials said.

Rockport Train 106 (7:23 a.m. from West Gloucester) was operating 45 to 55 minutes behind schedule, and Haverhill Train 290 (8:30 a.m. from Reading) was cancelled due to the disruptions on the Rockport line, officials said.
