I'm not arguing you can make something like this work. However it will cost a lot of $$$ and in the end you won't have anything better than known freight trains. Even if you convince every [geographical area the size of Japan] to install one, the scale factors still won't make this better or cheaper than a train.

But that's the thing, it has already been done, already been proven and it does work. Roads and classic freight rail are not the only thing that are used right now that do this.
