Greg,
Rember a museum is going to have a more accurate experior and interior than any of the tourist railroads.
The picture of the interior looks like D&RGW # 284. I am sure the museum would be happy to arrange a film contract to film on the property.
And do not forget that a 2-8-0 is much more 19th century than the 2-8-2 locomotives that the D&S And C&TS are using. Sadly no more D&RG 4-4-0s exist.
Another one is the Durango railroad Historical Society's #315; i bet they might even have some video or film to loan your producer!
