+1. Want energy-efficient, electric-based transportation? Electric trains between major routes, they could even be autonomous, or at least don't need a meat engineer on cockpit. Electric small trucks to carry from hubs to final destinations.

eHighway[0] anyone?

Likely not realistic. Rail in the US, speaking modernly, tends to wind up being an expensive boondoggle even on fairly short routes.

The US has one of the best freight rail networks in the world. It is far from a boondoggle. There is potential to further expand it, and reduce carbon emissions through electrifying tracks.

Passenger rail is a whole separate problem.

How much of that is legacy routes where the cost of securing rights of way, dealing with NIMBYs, etc, is long since sunk? It hasn't gotten any easier.

There are medians in the middle of every freeway in the United States just begging for train tracks.
