CARY — A motorist who was found stalled on the railroad tracks late Saturday night told police that her global positioning system had directed her there.

The officers managed to stop a train before it crashed into the woman's car. They then charged Robyn Michelle Walker of 7229 Aquinas Ave. in Raleigh with driving while impaired, according to court records filed at the Wake County Magistrate's Office.

Police also ordered Walker, 35, to surrender her driver's license for 30 days after she refused to consent to an alcohol breathalyzer test, court records show.

The incident occurred just before 11:30 p.m. on tracks at Trinity Road near East Chatham Street, police reported.

When police found her, Walker told the officers that her OnStar GPS directed her onto the tracks. Walker also told police that her car had stalled on the tracks and she wasn't sure whether she should abandon it, court records show.

After police stopped the train, they noted that Walker was shaken up but otherwise OK. Police also said that Walker did not appear to be a threat to herself or others, court records show.

A Wake County magistrate allowed Walker to be released without posting bond after she told them she had a ride home.

She could not be reached for comment Monday.
