Anyone know this passenger car?

So got this and I cant find anything online

Also this is the Southern Pacific variant it's mint and only out of box, it's from 1975 I believe



Tidmouth Sheds before Tidmouth Sheds lol

I believe that is the California Zephyr's Silver Solarium car

Thanks Super! I’ll check if it is

The type yeah, but not livery, mine is southern Pacific

I couldn't find an actual Southern Pacific example but there are several that used the Silver Solarium. I have also seen it called the Silver Splendor on a Burlington train.







Although you can't see the side of the car this photo is Captioned with "The Rear End of our Southern Pacific 4449 Train"

The Southern Pacific livery could've just been a fictional livery. It's not too uncommon for model train companies to release rolling stock in fictional liveries.

Hmmm,, it also could be a prototype, but I don’t think so, Thanks for you help Super and JT!
