Authorities say a cyclist has been struck and killed by a commuter rail train in Somerville.
Crews responded to a train crossing in the area of Park Street at 1:30 p.m. on Sunday. MBTA transit police said a male cyclist went through gates that had been lowered for an approaching train on the outbound Fitchburg Line and continued onto the train's right of way when he was fatally struck.
Police said the man was between 25 and 30 years old but did not release his identity. Other details were not immediately available.
Transit police and the Middlesex County District Attorney's Office are investigating.
