I wonder how passengers back then would have imagined rail travel today, 75 years later (aside from the life-threatening storms, of course). The Overland Route is now freight-only, and the closest equivalent, the California Zephyr, takes about 52 hours to make the journey this train did in just 40!
More on topic, I was surprised to read:

Weren't there surrounded by frozen water? Is there any reason snow couldn't be used in an emergency to heat the train?

I don't think people ride the California Zephyr to get from Chicago to the Bay Area as quickly as possible. Most of us spent as much time as possible in the observation car marveling at the Rockies and Sierras.

Of course they don't. It's too slow. Our rail shouldn't be as bad as it is.
I love that trip, and I've taken it more than twice, oohing and ahhing all the way, but I do not need it to last as long as it does.

1. The volume of snow to be collected would have been significantly greater than the resulting water.
2. Heating snow at elevation requires more energy.
3. Perhaps getting snow into the steam generator wasn't so easy.

Yes, dependent on the nature of the snow but a broad idea is that if you want a litre of water, you need five litres of snow.

Show them the airplane that gets them to the same destination in a couple of hours vs days

I have tried this.
Snow is not very dense. A lot of snow makes a very small amount of water. Quite an astonishingly small amount of water
I expect the steam generators were quite thirsty, I do not know.

That's why currently running steam engines are better off with diesel pushing them: https://youtu.be/12Zpb0Yh-sM

This was mostly a power problem. UP 4014 had a small steam turbogenerator atop the boiler to power lights and such. Now it has three such generators, and there's enough electric power to run auxiliary equipment.
UP did a serious rebuild on the Big Boy, to original main-line standards. Many parts were fabricated from scratch. It's ready for regular use for decades. Most heritage railroads lack the resources for such major overhauls.
Here's the first test run with no Diesel, in May 2024.[1]

The much bigger issue that steam is massively less dense that liquid water: roughly a 1:10 ratio. Loading up 10x more snow than you need water is no small task.

I mean, this is largely a product of the US's general disinterest in and underinvestment in passenger rail; with a modern high speed system it'd be about 10 hours.
10 hours is _probably_ too long to be particularly useful, mind you; people would just fly. The sweet spot for high-speed rail is more in the 5 hour and less range; at that point when you factor in the faffing around involved in getting to airports, going through security, the inevitable delays etc, the train is still faster.
The longest high-speed route in the world is about this length: https://en.wikipedia.org/wiki/Beijing–Kunming_high-speed_tra...

The Chinese route you mentioned does not need to go through one of the largest mountain ranges in the world. It's also at least 15-20% shorter than the distance from Chicago to SF, and experiences much less elevation change over the course of the journey. And the wiki article claims it "averages 10.5 to 13.5 hours", so there is a huge amount of variability in time to travel on that route.
