Travelling through wilderness

Well, the ARR trains are #1 in this category, no doubt. But actually I wanted to focus on trains between the Canadian and Mexican border.
But anyway, you´re absolutely right. There´s no less populated area in the US than in Alaska.

I would include the Alaska Railroad as well.

The Pioneer and the Desert Wind are two former Amtrak trains that would qualify.

Which US long distance passenger train ran (or still runs?) through the most unpopulated, emptiest and loneliest areas in the USA???

In my opinion, it´s the Sunset Limited. From a little behind San Antonio all the way to Los Angeles, there´s almost nothing than desert. El Paso and Tucson are the only bigger towns along the route, so you really have long runs through wilderness before reaching the next town.
A runner up to the Sunset could be the Empire Builder. Between Fargo and Spokane there is also a big area where almost no one lives.

So what do you think?
