Anatoly Unitsky's String Transport System (UST) may offer a cheap transport system that could stand to reduce the cost of traditional rail infrastructure.
Unitsky's proposed String Transport System uses steel and concrete rails suspended between 3 to 20 meters above ground, providing an efficient and smooth rail system. Being earthquake-, hurricane- and terrorist-proof, the rail offers security to the passengers. This genuine high-speed rail alternative is capable of supporting vehicle speeds traveling over 500 kmh.
Implications - The UST steel and concrete rails that are heavily supported ensure the trains can travel across rough terrain, mountainous territories, shallow waters or forests in a straight line, with high speed, efficiency and of course, little environmental impact.
