> To that end, Tesla has mentioned in their presentations that a Tesla Semi convoy of only 3 trucks can be cheaper than a train for the same load.

I can carry it on my magic carpet for even cheaper, trust me I am rich so I wouldn't lie... this time.

Trains have replaceable engines, power-lines - no battery. Trucks will not be cheaper option no matter what mumbo jumbo techno jargon you throw at it. And decades of technological optimizations. And they dont need lithium to be made and maintained.
