Abstract: The subject of the invention is stabilisation and levitation mechanism for a dedicated vehicle, taking into account interoperability with existing transport systems in the vicinity of switches and routes of conventional vehicles, containing the ground, on which the rails are fixed, wherein on both sides of the rail system, preferably on the track bed, at least along a fragment of the track used by conventional vehicles there are guiding walls, mounted on movable supporting elements.

Abstract: Railway system includes a railway vehicle movable along a railway guide system, the railway vehicle including a chassis and a carriage rotatably supported on the chassis via a pivot coupling. The railway vehicle further includes a pivot actuation system including an actuator and a control system connected to the actuator and to sensors for actuation and control of the rotation of the carriage relative to the chassis. The carriage is rotationally supported relative to the chassis about a pivot axis (P) that remains in a static position with respect to the chassis, the carriage having a mass distribution forming a centre of gravity (CG) positioned below the pivot axis (P), the pivot actuation system serving to assist and dampen passive rotation of the carriage relative to the chassis due to the torque generated by centrifugal force acting upon the centre of gravity about the pivot axis (P).

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.
