Abstract: A railway vehicle including an access platform which extends between two lateral faces, at least one of the faces having a lateral access door. The access platform is adjacent a passenger area and includes a plate which is movable vertically so as to allow passengers with reduced mobility to access/leave the access platform from/to a railway platform of a given height when the movable plate is placed in a given embarkation/disembarkation position. Also included is a moving floor allowing persons with reduced mobility to move between said passenger area and said movable plate whatever the embarkation/disembarkation position thereof. The moving floor is located and always remains in an interior of the vehicle along with the passenger area and the movable plate between which the moving floor is located.

Abstract: The invention relates to a railway vehicle including a body defining a wall in which an access passage is embodied, at least one closing sliding door, a sealing joint carried by the door and applicable to the wall when said door in a closed position. Said wall includes a panel provided with a generally cylindrical envelop and a seat which is protruded with respect to said panel and defines a bearing surface for supporting the joint only when the door is in the closed position, wherein said bearing surface of a supporting element extends along a profile substantially identical to the joint profile and said joint profile extends transversely with respect to the door displacement direction.

Abstract: Railway vehicle (1) comprising an access platform (4) which extends between two lateral faces (3), at least one of the faces comprising a lateral access door (2), the access platform (4) being adjacent to at least one passenger area (6, 6?) and comprising a plate (5) which is movable vertically so as to allow passengers with reduced mobility to access/leave the access platform (4) from/to a railway platform (27) of height Qi (i=0, 1, 2, . . . , n) when said movable plate (5) is placed in an embarkation/disembarkation position Ei (i=0, 1, 2, . . . , n), characterized in that said vehicle (1) comprises at least one means of passage (11, 11?) allowing persons with reduced mobility to move between said passenger area (6, 6?) and said movable plate (5) whatever the embarkation/disembarkation position Ei (i=0, 1, 2, . . . , n) thereof.

Abstract: A submarine system comprising a submarine device for operation within a fluid environment. The device is provided with a self-contained source of energy, propulsion components coupled to the energy source, maneuvering components and an environment observation device. A control station located remote from the submarine device is connected to it by means of a transmission cable, the cable being the sole means of transmitting command signals to the device and receiving observation results therefrom.
