Concept for mag-lev installed on top of existing railways
Advertisements [?]
There was a blurb on these people in pop-sci. One big component of the pitch is the savings in right-of-way, since it sits on top of existing rail infrastructure.

Until now, maglev systems have been maglev trains a nineteenth-century transportation mode with twentieth-century technology replacing the steel wheels, while still relying on mechanical track switching technology (i.e., circuit switching). These maglev systems promised greater top speeds, but that promise was limited by the tradeoffs endemic to train service: more stops meant slower average speeds, albeit for a larger potential passenger base; fewer stops meant higher speeds, but for a smaller potential customer base.

Moreover, the incremental speed improvements that existing maglev promises require completely new guideways constructed on new rights-of-way at tremendous cost over $100 million per dual-guideway mile (i.e., one track in each direction). That has been their downfall: maglev trains are simply too expensive and too limited in their practical value to be cost-effective.

There is a better way: a packet-switching transportation network that uses permanent levitation maglev and linear motors for instant track switching and direct routing of smaller carriages on an ultra-high capacity network for passengers, freight, and vehicles.
