A vehicular linear propulsion system for use along a track, comprising: a tubular drive line ( 3 ) divided lengthwise into a plurality of mutually-sealed sectors connected end-to-end by sector gate air valves (SG); at least one main supply pipe running adjacent, preferably parallel, to the drive line for the supply of air to the drive line or the evacuation of air from the drive line; at least two main air valves (V 1 , V 2 or P 1 , P 2 ) near respective ends of each sector for selective communication with the main supply pipe; and two exhaust air valves (I 1 , I 2 or E 1 , E 2 ) near respective ends of each sector for selective communication with the atmosphere for exhausting air or taking air in. |
