But freight? Easily handled by rail... at least a great big chunk of it. There is a network in place already that can be used while the expansion and electrification is underway. All you have to do is look at what it costs to send a 20 ton 40-foot container from LA to NY via rail and via truck.. in terms of fuel consumed.
Locomotives, the original hybrids. V16 and V20 diesels with pistons 10 inches in diameter, turbochargers all to power a generator and a compressor.
