I would joke about adding a hyperloop between Reno and the Bay Area :-) Actually rail is pretty reliable through there, more so than the highway.
I doubt these will be being shipped by truck given the quantities we're dealing with. I also would not doubt an improvement in the infrastructure for a corporation bringing 6500 jobs and $5bn into the economy.
There's an example of that kind of rail-clearing engine in Skagway, Alaska. I saw it there just over a month ago. That snow machine isn't used anymore--an historic museum piece on exhibit--but close up it is impressive.
