ok so where is this at? It does not look like most of Arizona.
I went spooking around the MA last year and actually decided I wanted to buy a house in Miami AZ on the other side of the hill, but some things got in the way with timing.
However I talked with a gentleman that turned out ran the museum there and he told me a lot of cool stuff about the status of things in the area.
The mine at Superior isn't actually shut down. while the smelter is gone, (the stack remains) they are working around a huge pocket right now slowly and will eventually begin mining it. He told me the reason the RR has been left in place and semi maintained is it will need to operate once the mine is fully working again. He threw out a year of 2020 for possible operation of the mine based on what he had heard so who knows that would be really great to see trains rolling out there again.
