You are correct Charlie, it was Emil Madorin who was with Eldon that day. When I wrote the article I got Emil and Roy crossed up. The other thing Eldon talked about was was the pic that Jim Shawnessey took of 487 at speed south of Alamosa. Eldon was the fireman looking at the the "crazy guy hanging his big camera out he window of his car while drivng with his knees". Roy was the engineer.
When I read the above linked article I thought "hmm, sounds like the piece I did", when I got to the Roy Turney bit I said, "yep that's my screw up alright".
