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 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.

“He’s shaken up about the situation, and we are working to make sure that he receives any care that he needs. We’re doing everything we can to find the rest of the crew,” Espinoza said.

Law officers were searching areas near the tracks to determine if the missing crewmembers had escaped injury, Oklahoma Highway Patrol trooper Betsy Randolph said.
