Airborne Trains Traveling on Strings

Unitsky String Transport (UST) is a transportation system developed by Russian inventor Anatoly Unitsky as a railway consisting not of steel tracks bolted to ties but rather elevated high-tension concrete- and steel-enveloped wires strung between towers, thereby offering rails that can traverse uneven terrain, forests, or water without the prohibitively expensive infrastructure required by conventional transit systems. Furthermore, UST can traverse obstacles in a straight line, thereby obviating the need to circumnavigate impediments or build switchbacks and considerably reducing the distance between two points.

Unitsky began developing the concept back in 1977. His design uses high-tension steel wires inserted into a concrete-resin core and enveloped by steel shells and elevated from three to 30 meters from the ground (or potentially even higher, if the terrain necessitates it). While this might sound like a conventional ropeway (like a chairlift or the Roosevelt Island Tramway), it differs in its much higher cable tension with sag of less than an inch between support posts, allowing vehicles to travel along the wires with a minimum of drag and at speeds, according to Unitsky, of between 200 and 300 mph. “In fact,” according to newatlas.com, “it’s more accurate to look at a UST track more or less as a tiny pre-stressed concrete bridge, built for a fraction of the cost of a ground rail system or even a motorway.” Continue Reading…
