BIDDEFORD — Authorities have not yet released the identify of the person killed by an Amtrak Downeaster train Monday.

Cliff Cole, an Amtrak spokesman, said that no additional information was available about the incident, which took place around 3 p.m. near Main, Cutts and State streets.

“We don’t have an identity to give out yet on the trespasser or any other follow-up at this point,” Cole said in an e-mail message today.

The person struck by the passenger train while walking on the right of way was not carrying identification. Cole would not say whether authorities had identified the person and were trying to locate next of kin or whether they were still trying to determine the person’s identity.

No one else was hurt in the incident, which involved a train heading to Boston from Portland.

Amtrak, Pan Am Railways and Biddeford police are investigating. The probe is expected to include evidence from the scene as well as videotape from a camera on the front of the train.
