HOQUIAM, Wash. (AP) - A Hoquiam woman was cited for assault, trespassing and resisting arrest after she was discovered half-naked hanging upside down from a train ladder, police said Tuesday.

Robin Bishop, 31, was taken into custody about 2:30 p.m. Monday, after an engineer on a Puget Sound & Pacific train discovered a woman hanging from the rear of the train as it approached a bridge here.

"She was wearing jeans and nothing else," Hoquiam police Lt. Mike Whittaker told The Daily World of Aberdeen. "She was hanging upside down, topless, from a moving train."

Police Capt. Jim Maloney said engineers stopped the train, which had only four or five cars, and approached the woman. She yelled at them and struck one with a rock before climbing to the roof of the car.

"The officers thought she might have been under the influence of alcohol ...," Maloney said.

Police don't know how the woman got onto the train.

The woman's feet were bloodied, apparently cut on rocks as she walked along the tracks, police said.
