I took the Pacific Chief, the train from Chicago to Los Angeles. Got off at the stop before Albuquerque, but it's right after going thru a mountain pass. Train was literally going about 20 mph around the tight turns, where if you fall off things could be quite bad. Power poles out there still have wires attached and presumably still working, but old fashioned glass insulators (varying colors so quite colorful and scenic) and falling down, so the wires are stretched in many places. It's the kind of place that doesn't change in 1000 years. In Switzerland they'd just blast out a tunnel under the mountain.
Quite a few Amish on that train. It seems they approve of trains but not of airplanes, even though that train surely had a diesel engine not an old timey steam engine. They stay before 1900 tech I guess.
It was very nice, lots of scenic views. Protip: bring all your food for the trip onboard with you. There's never an opport unity at a stop to get off, get a proper meal even to go and get back on, and they try to sell their overpriced dining car meals. You can bring vast amounts of luggage for free.
