A 20-year-old woman was struck and killed by an Amtrak train Monday evening near Sunnyside Beach Park in Steilacoom, according to media reports.

Gus Melonas, a Burlington Northern Santa Fe spokesman, told KING-5 News that witnesses reported several young women near the double mainline tracks.

The woman was hit by a southbound Amtrak headed from Seattle to Eugene, Ore. She was not immediately identified.

Steilacoom police chief Robert Drozynski told the TV station that there is a pedestrian crossing in the area with a warning horn, flashers and a rail crossing sign.

The Amtrak train and a freight train were held up for several hours while the incident was under investigation.
