That's no way to run a railroad.
They can't even spell the name of the turbine right; it's Darreius, after George J Darreius who invented it in the 1930s.
There's so much wrong with this, I hardly know where to begin.
First, the Darreius turbine is not self-starting, so is the worst type to use when the wind is intermittent, as in traffic. The Savonius type would be the cheapest usable alternative. Those annoying rotating signs work roughly that way.
Second, the way it's shown in the magazine, it would replace the crash barriers and could turn a fender bender into a pileup. Even without a pileup, the repeated damage to turbines would make the system prohibitively expensive, unreliable and difficult to maintain.
Third, even a modest 2 car light train needs at least 150 kilowatts for a quick getaway from a station, and there's no way those turbines could do that. A backup energy store or a connection to the power grid would be essential. Better designed and located located wind turbines can assist the grid.
That's it. The article already demolished the other foolishness.
