:shakesfist: Phinnaeus, you used my idea which I got from somewhere else.

It is amazing tech, so can't really blame you.
In the Bloom Box videos, the CBS version, there is a BTVC who got the $400Million for Bloom Box, 4x the initial projection. You could argue it was over funded.
Is there a loss over distance, electrically?
Are the rails levitation susceptible to interference induced currents generated by something like solar magnetic storms, static electrical fields, an EMP, or microwave radiation?
Is it possible to discharge a rail intentionally or unintentionally?
Another point, the entire line would be limited in acceleration time, 0-350mph, by the most acceleration sensitive items. A tomatoe may only handle an accelration of 0-350mph in 15 seconds while a refrigerator could withstand accelration from 0-350mph in 7 seconds. Therefore, the entire lines shipping time doubles by adding tomatoes to the shipping line.
If you had multiple load and unload points in between start of line and end of line, how would you handle shifting cars, or cargo, on and off of tracks?
How would you handle track length, if your not shifting cars off?
The track would have to be 3x the distance of the actual start and end transportation points.
A loop would be more efficient I guess, but would that work with the electrical systerm in the rails?
How about Canada's logging, mining industry? Or even there great expanse of wild from east to west?
