SPOKANE VALLEY, Wash. -

Spokane Valley investigators are trying to figure out if a car hit by a train Friday night was intentional or if the driver experienced a mechanical problem.

Just after 6 p.m., the Spokane County Sheriff's Office said a woman was driving northbound on Pine when she apparently drove under the railroad crossing guards and stopped on the tracks.

A train traveling eastbound hit the car and pushed it several yards away.  The vehicle eventually came to rest upside down. The driver, a woman in her late 40's, was extricated out of the car and taken to a local hospital in critical condition.

"Just a huge reminder to the motoring public that when those arms come down, obviously they are coming down for a reason," said Deputy Craig Chamberlin.

"...The good thing is as far as speed wise, it [the train] wasn't going that fast because it was able to stop in a relatively short amount of time after the collision," he added.
