Gravity-vacuum transit (GVT) is a passenger transportation system employing gravity and vacuum for propulsion. This report describes an urban GVT system to provide a baseline for further study. The general concept employs trains that travel through steel tubes in underground tunnels and that are accelerated and decelerated by gravity and atmospheric pressure. The trains use wheels on rails inside the tubes. The tubes are evacuated by electrically-powered pumps or compressors located near the stations. (Author)
