Gadgetbahn

To cite a favorite example of gadgetbahnen enthusiasts, automated train operation is as easily applied to conventional rail as monorails, as demonstrated by the Vancouver, BC, Skytrain (which uses standard railroad technology, not monorail as some Seattle monorail boosters apparently believe). […] To some extent, the promising concept of bus rapid transit (BRT) has also suffered from the "gadgetbahnen" mentality.

Ken Avidor, a Minnesota transit advocate and critic of similarly proposed systems, called the project the latest iteration of "gadgetbahn," a play on "autobahn" the German word for freeway. Gadgetbahn refers to highly technological transport systems relying on untried innovations. "All of these gadgetbahn projects always rely on totally unrealistic cost estimates," he said.
