What are you talking about?
When it comes to long-distance rail lines in the USA, they already exist. They just don't carry passengers, and some of them have had the rails torn up and sold for scrap. But to electrify existing lines, or even rehabilitate abandoned ones, doesn't require laying out alignments and acquiring land along them.
Besides, when it comes to road project, there's somehow never any problem getting the land, even for privately-owned toll roads.
