CHICO — A woman was killed crossing the railroad tracks around 5:30 p.m. Saturday at West Eighth Avenue.

Michael Pierce, a witness who called 911, said that a woman was trying to cross the train tracks when she got caught in the crossing guard. Pierce was driving home when he saw the woman get hit.

Pierce said he was sitting in the second car in a line waiting for the train to go by when he saw two people cross over the tracks heading toward Nord Avenue.

“Behind them was a lady trying to do the same thing, and it looked like either her shoulder got stuck in the rails or she had regrets or she was trying to turn back,” he said. “Either way, she was struggling and the train went by.”

When the train started to stop, he got out of his car and ran to the front of the train to see if he could find the woman, he said, but he couldn’t see anything.

Pierce called the police, and they found her body under a billboard.

Chico police said more information will be released soon. The roadway was closed at the roundabout at Greenwich Avenue and at Nord Avenue until about 8:45 p.m.

8:55 p.m. update: The roadway is clear and the train is moving, officials said.

This story will be updated as more information is available.
