BIDDEFORD — A person was struck and killed by an Amtrak Downeaster passenger train on its way from Portland to Boston on Monday afternoon, according to investigators.

The accident happened around 3 p.m., when a train carrying 55 passengers hit a person on the tracks about 400 feet west of Main Street, where Cutts and State streets meet near the railroad right of way.

No passengers or crew members were injured, but the train was delayed nearly three hours while Amtrak, Pan Am Railways and Biddeford police investigated, said Amtrak spokesman Cliff Cole.

Investigators will review evidence gathered at the scene, as well as videotape from a camera on the front of the train.

No information about the person who was killed was available Monday night.

The person, who was carrying no identification, was breaking the law by walking in the right of way, which is owned by Pan Am, investigators said.

However, there is no fence or warning sign to keep pedestrians from wearing a path from the end of Cutts Street to the railroad right of way. Many people in the intown residential neighborhood use the tracks as a shortcut to Biddeford High School and other destinations.

“It was a major concern when I moved into the neighborhood because I have three small children,” said Marilla Martin, who lives on Cutts Street. “You see people going back and forth all the time.”

Denise DiGiovanna, who lives on State Street, heard the train screeching to a halt when the accident happened Monday afternoon.

She was glad all of her children were home at the time so she didn’t have to worry that one of them had been hit.

“There should be a fence or at least a sign along the tracks,” DiGiovanna said. “There are too many kids in this neighborhood for it to be open like that.”

Regular train service resumed around 5:45 p.m.
