OKLAHOMA CITY (AP) - Oklahoma's medical examiner's office says it has received the remains of three Union Pacific crew members killed when two trains collided head-on in the Oklahoma Panhandle.
Spokeswoman Amy Elliott says the medical examiner's office in Oklahoma City has received the remains of three men pulled from the wreckage of the Sunday morning crash near Goodwell.
A Union Pacific spokeswoman did not immediately return calls or emails seeking comment.
The National Transportation Safety Board is investigating why the two trains collided on the same track, causing a white-hot diesel fire that burned for more than a day and made it too dangerous for crews to enter the wreckage.
The agency says it found no problems with the train signals, and investigators are trying to determine which train should have yielded.
