Abstract: Vacuum tube railway system comprising a vacuum tube mounted on a ground support, a magnetic levitation railway track mounted inside a wall forming the vacuum tube for guiding a magnetic levitation railway vehicle, the vacuum tube assembled in sections along the ground support, at least some of a plurality of sections of vacuum tube being coupled together by a dilatation joint configured for hermetically sealing a dilatation gap between said sections of tube. The dilatation joint comprises at least first and second support plates mounted on an outer surface of the tube wall, a first support plate fixed to a first section of vacuum tube and a second support plate being fixed to a second section of vacuum tube, the support plates extending longitudinally over the dilatation gap over a length (L1) greater than a maximum dilatation gap (G).

Abstract: Magnetic levitation railway system for integration in a wheel railway track, comprising a magnetic levitation railway track including a linear motor and magnetic levitation rails arranged on outer sides of the wheel railway track, said magnetic levitation rail comprising a conductive guide rail having at least a horizontal portion configured for a magnetic levitation railway vehicle having a levitation device with magnets. The guide rail is configured for passive levitation of the magnetic levitation railway vehicle due to the electromotive force generated by the moving magnets of the magnetic levitation railway vehicle.

Abstract: The disclosure describes an airlock with a pneumatic orifice, characterized in that the orifice chamber is located inside the tunnel, together with an inactive expansion element made up of a flexible material consisting of an external torus and an internal membrane, which is activated by compressed air produced by compressors placed in a housing.
