Russia worked on a system similar to the Bennie Railplane in the 1930s and were even planning a 332-mile line through Turkestan with a top speed of 180 mph. Their system was unique in that it had two side by side cars suspended on one rail, and it could actually dismount from the rail to cross rivers as an amphibian and then on the other side remount the rail. And while elements of this system were tested in Moscow, the Russian government instead built a conventional rail system.
