The ultralight two track train that does not derail, made up of one or more ultralight wagons and aerodynamic, oval or semi-oval transverse profiles, characterized in that the wagons carry vertical or inclined wheels or pulley wheels in their lower area and supported by the chassis of the wagons, which rest and roll on a pair of vertical or inclined rails, the channels of the pulley wheels are supported and held on the head of circular, semicircular or semi-oval section of the rails, the heads of the rails being trapped with the pulley wheels, adding pairs of wheels that use a common axis, the rails are coupled and fixed tongue and groove to the sleepers or to some monolithic structures or channels, the sleepers are fixed using the track system on concrete slab, using electrical supply means, propellant means and reducing means of the front, rear and lateral resistance of the wagons, adding wheels with permanent magnets or with electromagnets that are attached, or run close and attracted by the rails.

A rail-borne vehicle includes an inner ceiling assembly having at least one air duct, a multiplicity of lighting devices and at least one ceiling cladding. The air duct is disposed between an inner surface or face of a roof of the rail-borne vehicle and the ceiling cladding and the air duct is provided with a multiplicity of air outlet openings. The ceiling cladding also has a multiplicity of openings. Both the lighting devices disposed between the inner surface of the roof of the rail-borne vehicle and the ceiling cladding as well as the air outlet openings of the air duct are disposed relative to the openings in the ceiling cladding in such a way that both the air of the air duct and the light of the lighting devices pass through the openings in the ceiling cladding.

A rail vehicle for transporting passengers includes at least one car body, a passenger compartment situated in the car body, an underfloor region, an inner ceiling region, and a plurality of device containers for receiving vehicle components. The passenger compartment includes a first end wall region and a second end wall region which is situated opposite the first end wall region. In order to enable a great configuration freedom for the passenger compartment, it is provided that each device container of the rail vehicle is disposed in one of the above-mentioned regions.

Water barrier systems may include a first mobile water barrier and an adjacent second mobile water barrier. Vertical position control mechanisms may be configured to lower sidewalls of the mobile water barriers. The mobile water barriers may include sealing elements to form water seals between the adjacent mobile water barriers and between the sidewalls and a surface adjacent to the water barriers. Related methods of forming a water barrier assembly are also disclosed.

A movable footboard for a door of a rail vehicle comprises a footboard extendable below a tread strip at least substantially transversely to the direction of travel. To minimize the level difference between the footboard and the tread strip a pivot shaft extends at least substantially parallel to the direction of travel on at least one longitudinal bar of the footboard at the end region of the footboard away from the vehicle, about which pivot shaft at least two pivoting bars are pivotably supported, which pivoting bars each bear a transverse profile element, each of the pivoting bars being rigidly connected to the transverse profile element associated with the pivot bar, while the other transverse profile elements lie freely on said pivot bar, and a lifting mechanism is fastened to the vehicle and lifts the transverse profile element located directly in front of the tread strip.
