Right piece of track Roger. We always stood on the hillside somewhere between the 41 and 51 second mark. Seems to me that if the drone were on the hillside of the train in that area, the sun would be better on the fireman side of the engine. Also you should be able to look across at Lobato Trestle from somewhere over there.
If I were doing it I would start close to the trestle, then while its going into the loop and trees, head for the area I mentioned and get it coming out of the trees, with the trestle in the background. The whole area is a nice clean view, but a lot of those trees were not on the hillside in 1993!!! That was only 25 years ago! Nice of you to order up such nice clear sky and smoke too!!! Helps to live their, eh!!!
Been busy working on vintage 40's-68 material of D&RGW.

PS. I would also try some sort of shot in the wolf creek looking up, or straight broadside of Lobato trestle. What the heck, you are right there with a working drone! So far I have had zero steam fix in 2018!
