Floodlights were brought to the crash site near the town of Panhandle late Tuesday night. Flames were blocking efforts to search the wreckage for the missing crew members.
The two BNSF Railway freight trains were on the same track Tuesday when they collided. BNSF spokesman Joe Faust says each train carried two crew members; one man jumped before the collision. He was in stable condition at a hospital.
The collision caused freight cars and containers to derail.
