CLAREMORE, Okla. (AP) -- A Claremore woman and two of her children died Sunday when the vehicle in which they were riding failed to stop at a railroad crossing and collided with a freight train.

31-year-old Cindy Wilson; her two-month-old son, Kaleb, and 10-year-old daughter, Stephanie Smith, all died at the scene of the 9:06 AM accident in Rogers County.

The Oklahoma Highway Patrol says Wilson's husband, Donald Wilson, who was driving, and their 2-year-old daughter, Victoria, were flown by helicopter to a Tulsa hospital and are in fair condition.

The patrol says the Wilsons' vehicle was traveling south on a Rogers County road when it pulled in front of the northbound train at a railroad crossing. The impact threw Cindy and Victoria Wilson out.

The train's conductor and engineer weren't hurt.

Another vehicle traveling on the other side of the tracks wasn't hurt when debris from the collision hit her car.
