Need help with identifying this location on the SP

Here is a picture of the heavyweight pullman green C&NW/UP/SP joint train “Pacific Limited” (Chicago-Oakland), here being pulled by a SP GS-4 class locomotive maybe in the late 40ies. Can anyone tell me where this location exactly is? Could it be somewhere in Nevada??

Admittely this is a shot in the dark but the first place I thought of when I viewed the picture is Palisade Canyon in Northern Nevada. I’ve driven through the area many times on I-80 and the landscape is a match, but more importantly in the far left side of the picture there appears to be another ROW on the opposite side of the river (Humbolt River).

Again, this is just a guess, see more modern pictures here of the location I’m talking about.

The popular photo location is the twin bridges, your picture could be in a more obscure location.

The train is eastward on WP track, either compass-northward here

or on the next straightaway east of there. I’m guessing the former.

As I recall the Pacific Ltd should run thru there at night-- Challenger or Gold Coast seems more likely. Pacific Ltd and Challenger were discontinued 1947.

Edit: the pic was in 2/46 Trains, so it can’t be the Gold Coast; if it were the Pacific Ltd it would have to be maybe 10 hours late. Probably the Challenger; dunno if the consist rules out the Overland.
