CW-7

Regarding your first paragraph, my theory isn't incompatible with that. What I'm saying is SP was built pre-freeze to travel around the world, mostly at high altitudes in mountain ranges, because the engine runs on snow/water, which it converts into hydrogen for fuel.

The motive of Wilford and Melanie to launch CW7 was to stop the preFreeze snow from melting, so the train could continue to function.

Regarding the water - yes the train stores water, but I don't think it can store anywhere near the amount it would need to run through an arid environment. The weight and space needed to store the water reserves would be too great, the train wouldn't be able to pull anything else.

Again, just a pet theory, but I don't think anything you've said above makes it implausible.
