Glad you enjoyed it. Thank you. The only position available was a backlit one so I got what I could

[@GaryA]

So THAT'S where they added the diesel.

[@MarkTraain]

Yes and they were supposed to pick up more passenger cars in Ogden.

[@MarkTraain]

[@RailfanKnexified]

Why did they add the diesel? Was it for the dynamic brakes?

[@GregoryVeizades]

Yes, and range extension over the grades.
