I rented and watched a movie called "The Claim" this past weekend--a kind of neo-Western intended to be more gritty and less romantic than the conventional western. Probably not to everyone's taste.
Leaving aside the artisitic merits, however, the film included some nice shots of the D&S standing in for the Central Pacific RR in 1869. The idea was to protray the cosntruction of the CPRR through the Sierras. Whoever was the technical advisor did a superb job--the railroad and equipment were shot in such a way as to underplay the anachronisms (the 1920s-era 2-8-2s only appeared in dim long shots) and play up the overall similarity in size of the narrow gauge equipment (especially wooden boxcars and flats) to stanadrad-gauge equipment of 1869, and the similarity of the San Juan terrain to the CP in the Sierras. I thought it was all very well done, and kudos to whoever advised the production company on the shoot.
