FAIRFIELD — An unidentified person was hit by a train at the Fairfield Metro train station Wednesday night, leading to delays on the Metro-North Railroad’s New Haven Line, according to police.

Fairfield police alerted the public to the incident around 7:30 p.m. Fairfield police said units were on scene at 300 Ash Creek Boulevard alongside Metropolitan Transportation Authority units investigating after a “pedestrian” was hit by a train.

Metro-North Railroad said it received initial reports of the incident closer to 7:15 p.m., but did not provide much more information regarding what happened, including the person’s condition.

One of the riders on the train told Hearst Connecticut Media that it was the 5:46 p.m. train out of Grand Central Terminal. Metro-North Railroad confirmed that was the train involved in the incident.

Metro-North said delays are expected on the New Haven Line of service between Southport and Fairfield Metro as police investigate the incident.

Around 8:10 p.m., Metro-North tweeted that the New Haven Line was seeing delays of up to 35 minutes because of speed restrictions between the Southport and Fairfield Metro stations.

Just before 8:40 p.m., Metro-North said the New Haven Line was seeing delays of up to 20 minutes because of speed restricutions and single-tracking between Southport and Stratford.

Around 9:40 p.m., the New Haven Line continued to experience scattered delays of up to 15 minutes because of the speed restrictions and single-tracking between Southport and Stratford, prompted by the person being hit by the train.
