Abstract: The method for evaluating the compactness of a layer of railroad ballast near a railroad tie includes at least one step of taking at least two measurements (11,11a,11b) of the penetration resistance (Qd) of the ballast (13) near one and the same railroad tie (10), and a step of calculating the mean value (Qdmean) of these measurements (11,11a,11b) of penetration resistance. Also provided are a device for implementing such a method and a method for predicting the settlement of the ballast of a railroad track including a step of evaluating the compactness of a ballast near a railroad tie.

Abstract: Exemplary double-decker vehicle for railway rolling stock for the transport of passengers comprises at least: one lower deck and one upper deck, each deck having a multiplicity of seats for passengers, and at least one access door with an access step. According to aspects of the system, apparatus, and method, the vehicle can include, among other features, a circulation system connecting the access step to the upper deck and having at least two sloping circulation paths to provide access for persons with reduced mobility to the upper deck.

Abstract: Table designed to be set up in a passenger railway vehicle and positioned between at least two seats facing each other, the said table comprising at least two folding trays, each tray facing a seat and comprising a first portion hinged to a second portion at an edge characterised in that it comprises a fixed housing positioned above the plane defined by the trays when they are in a horizontal unfolded position, the said fixed housing being capable of receiving the trays when they are in a vertical folded back position in which the first and second portion are arranged vertically against each other, the second portion being hinged to the fixed housing at an edge opposite the edge cooperating with the first portion of the tray.

Abstract: Device for locking the door of a toilet cubicle comprising a door locking element operated manually from inside the cubicle, the said locking element allowing the vacant and engaged states of the cubicle to be selected and the door to be locked when the engaged state is selected, the said device including an information mechanism located on the door at least on the outside of the cubicle and providing at least two tactile and visual indicators of the state selected by the locking element, characterized in that the information mechanism includes raised pictograms to provide a tactile indicator.

Abstract: The invention relates to a method for detecting impacts on areas to be monitored on a running vehicle (2), created by objects projected due to its velocity, wherein vibration sensors (11a-11d) are arranged in direct contact with areas to be monitored on said running vehicle (2) and the signals from the vibration sensors (11a-11d) are analyzed to detect impacts. The invention also relates to an impact detection system on areas to be monitored on a running vehicle (2).

Abstract: An acoustic attenuation device including an elongated hollow body having an open upstream end taking the form of a head for coupling to a compressed air outlet, and a closed downstream end, the hollow body having a sidewall with a plurality of air exhaust openings arranged in the downstream part, where the hollow body contains at least one upstream buffer lining forming a longitudinal filter and at least one downstream filtering lining forming a sheath.
