Wouldn't building a railroad be a more cost-efficient way in Alaska than trucking?

Depends on the terrain, and for such a lightly-trafficked place that would probably be uneconomic.

China could do it in Tibet which seems to be similarly populated/trafficked, on top of thawing permafrost. It's only 414 miles as well whereas the Tibet one is 1215 miles.

Tibet has millions of people. Prudhoe Bay has a couple thousand people and some oilfields.
