Pax High speed rail is only efficient out to about 650 miles, then aircraft are more efficient...with current technology.
Ships are the most efficient for freight. Over land, rail freight is the most efficient.
Automobiles are efficient to about 150 miles, that is one of the reasons that US transportation efficiency is suffering...not enough high speed rail for pax, not enough freight rail, and too many trucks/autos.
