A Lehi teenager was killed and his friend critically injured when their car collided with a Union Pacific train.

Killed was:Daniel Price, 16, Lehi.

Cassidy Johnson, 16, also of Lehi, was airlifted to Utah Valley Regional Medical Center with traumatic injuries to the head and body. She was later transported to University Hospital, where she is listed in critical condition.

The car was struck on the right side by the train as it crossed the road at the 300 S. 2000 West Lindon crossing, said Orem Police Lt. Karl Hirst. Signal lights were flashing and warning bells were ringing at the time, Hirst said.

The impact sent the car into a signal box on the south side of the intersection and off into the embankment, ejecting Johnson and flipping the car onto her.

Price was pronounced dead at the scene. The accident occurred at 6:50 p.m.

Hirst said the engineer watched the car parallel the train as the teenagers headed south to the intersection and worried about whether they would heed the warning horns.

"It looks like they tried to beat the train," Hirst said.

It isn't clear which teenager was driving the vehicle owned by Johnson, he said.
