well i don't mean to be rude, but this idea seems fairly odd to me. as others have already pointed out, the ARR is already in place. there is also ample bus service. moreover, many alaskans live in coastal towns (juneau included) that are only accessed by, wait for it, boat or plane. so to put in a rail system where there aren't even roads seems a wee bit far-fetched. but hey, you get points for thinking outside the box!
I lived in Anchorage in the early 90's, and often took the train in the winter-My neighbor was an engineer, and I'd ride the once a week train during the winter with him. Didn't go all the way to Fairbanks, it's winter schedule only went as far as Hurricane Gulch, (which is amazing!) but it was fun. Train consisted of a single RDC Budd Car, so got to ride the "head end". Was pretty cool, it was a flag stop, so any hunter, or homesteader could just flag down the train, and hop on. Made a few of those stops. Pretty neat trip to take! Of course, it's dark late, and early up there, so not much to see out the window for more than a few hours, unless you're up front looking fwd. (even if you don't get to ride "in the cab", as I remember if the separation was glass windows you could still see fwd through.
