Abstract: A railway vehicle, including an emergency braking device including at least one brake module, wherein each module includes a contact element intended to be in contact with the ground at the moment of braking, and movable between a retracted position and a deployed position in which the contact element is in contact with the ground and is able to slow down the moving railway vehicle by applying a pressure force to the ground, and at least one control unit that is capable of communicating commands to the brake module, wherein the control unit is able to communicate to the brake module the command to deploy the contact element to its deployed position when at least a portion of the vehicle leaves the track on which the vehicle is traveling.

Abstract: The vehicle including an active suspension system (22) parameterized by a set of adjustment parameters. The railway track is cut into segments. For each segment (T), the method includes campaigns for optimization of the set of parameters, such that: during the first campaign, to each passage of the suspension system (22) on the segment (T), a first set of parameters, specific to this passage, is predefined and applied to the suspension system (22), and a comfort quality index is calculated, and then a metaheuristic algorithm is applied for determining second sets of parameters, and during each following optimization campaign, at each passage of the suspension system over the segment, one of the determined sets of parameters by the previous optimization campaign is applied to the suspension system, and the comfort quality index is calculated, and then the metaheuristic algorithm is applied in order to determine new sets of parameters.

Abstract: A system includes an onboard device and a ground device. The onboard device incorporates a geolocation device, a plurality of sensors and at least one shaping module for the raw measurement signals delivered by one or more of the sensors to generate at least one formatted signal. The ground device incorporates a computer able to analyze the at least one formatted signal, to generate at least one indicator relative to the track and/or the rolling stock, the indicator making it possible to detect a damage and monitor variations of the damage so as to optimize maintenance of the track and/or rolling stock. The computer is a damage module able to compute the indicator from the at least one formatted signal and a model of the type of the damage monitored.
