Turkestan, which encompasses much of modern-day Central Asia, is rich in natural gas and oil resources. The reserve of mineral wealth, however, required a long journey through the deserts and down the Amu Darya river. To ease travel, the Soviet government planned three amphibian monorail lines capable of moving at 180 miles per hour. Twin air-propelled cars would carry 40 passengers. Upon reaching the river, the cars would be taken off the rails and used as a boat. In total, their monorail line would measure 332 miles in length, and each car would come equipped with a diesel-electric motor, a fuel tank, and a water ballast. Since it was the year 1934, however, the Soviet Union got caught up in more pressing matters, leaving the project all but forgotten.
