Three Union Pacific Railroad crewmembers were missing after two freight trains collided Sunday in the Oklahoma Panhandle, authorities said.

An eastbound train carrying vehicles and a westbound train crashed about 10:08 a.m. Sunday, June 24, 2012 near Goodwell, Union Pacific spokeswoman Raquel Espinoza said. A two-person crew was aboard each train, and officials were unable to account for two engineers and a conductor, Espinoza said.

The other conductor appeared to be uninjured, and officials were interviewing him about what happened, she said.

Law officers were searching areas near the tracks to determine if the missing crewmembers had escaped injury, according to Oklahoma Highway Patrol troopers.

Two locomotives on the 80-car westbound train and a locomotive from the 108-car eastbound train caught fire after the collision, Espinoza said. One train was hauling a resin solution, but Espinoza said that load wasn’t on fire and was doused with water as a precaution.

At least one firefighter was taken to a hospital for treatment of a heat-related injury after temperatures climbed past 100 degrees in the area and other firefighters were treated for similar ailments at the scene.

A National Transportation Safety Board team was en route to the scene Sunday night.
