Heard on KNX news radio: An Amtrak train collided with a car that was on the tracks but not at a crossing. One person in the car was killed, another was injured. No one on the train was injured, but the train was unable to proceed after the collision, and buses were brought in for the passengers to continue.
Very little other information given. It was somewhere between Sacramento and Bakersfield (that’s a lot of territory); no word on whether it was northbound or southbound, push or pull mode, etc.
