LEHI — Police identified the woman who was killed and her husband who was injured after the truck they were in was hit by a FrontRunner train Saturday.

Barbara North, 71, died after the vehicle she was a passenger in was struck by a FrontRunner train. Her husband, Darrell North, 83, remained in critical condition Sunday, but his state was improving, according to Lehi Police Sgt. Bart Smith.

A truck driven by Darryl North about 6 p.m. became stuck on the railroad tracks between the crossing grades on Lehi at 500 W. 300 North, and was then hit by a FrontRunner train.

"The man may have not gotten across the tracks before the arm on the opposite side came down, and he may have gotten confused and stopped on the tracks," said Remi Barron, Utah Transit Authority spokesman.

The Heber City couple was transported from the scene for medical care. Barbara North died after being transported to Mountain Point Medical Center, Darrell North was flown by medical helicopter to Utah Valley Medical Center, according to Lehi police.

The 90 passengers on the train were uninjured and were bused to another train after significant delays, police said. Police used the incident to remind people that they should drive through railroad crossing arms if they find themselves on the tracks.

"Those arms are designed to break away, and people should just keep going if they don't think they are going to make it before the other arm goes down," Barron said. "The arms are made to break away and they are easily fixed."

The train was travelling at the posted speed of 50 mph during the incident.
