What The Rail?!?!

(Alex Goldmark, Transportation Nation) In response to our series on the future of transportation, we got an email pointing us to "tubular rail." ????????

In this vision for an alternative train type, there is no track. Stanchions, 100 feet apart, house rollers that propel the train as it passes.  The train doesn't fall even as it's nose is suspended unsupported in the same way that a pencil on the edge of a tabletop won't begin to tip and fall until more than half of it is dangling past the precipice.

The website for Tubular Rail Inc. explains how the proposed plan would work, and answers many questions about top speed, power sources, emergency evacuation and braking.

Engineers?  Responses?
