Countryside

During our 3 long train rides I have seen a bunch of central chinese countryside, and I have to say, it sure is full of people. Is there any 24 hour train ride you could take from anywhere to anywhere else in Canada that wouldn't spend at least some of the time traversing wilderness? I don't mean pristine arctic wild lands, but at least some area where you don't see houses, or farms or settlements at some point? We haven't gone through anywhere here where you don't see a farm or a road, or people working, or houses or some signs of people. I guess up in the north there is desert, and out in the west you have the Himalayas, but around here it is people people people.
