An engineering baseline definition of an urban fast transit link transportation system consisting of vehicles riding on steel wheels in underground evacuated steel tubes, using gravity and differential air pressure for propulsion and braking. Stations are on-line. No switching is required. 25K and 50K/hour capacities are discussed. (UMTA abstract)
