Under closer scrutiny, all of the lines were railroads, and not highways. In fact, (I don't think) there were no highways at all. And it was all railroads, not just ATSF. I don't recall the date on the map.
Just a fascinating "other view" of the world to look at the US through that lens.
You can look at https://openrailwaymap.org/ for an up-to-date rail-only map of the world.
Note it's infrastructure: lines may be freight-only, or only used occasionally.
