Abstract: An assembly includes a locomotive, equipped with a roof line, electrically connected to a pantograph, a control system and a sensing circuit. The control system orders, depending on the voltage on the roof line detected by the sensing circuit, the open or closed state of a switch between the roof line and a power supply circuit of the motors of the locomotive. The assembly also includes a tender, coupled to the locomotive and carrying batteries suitable for delivering a current for supplying the motors. The tender is electrically connected to the locomotive in such a way that a first terminal of the batteries is connected to the roof line and a second terminal of the batteries is connected to a point of the locomotive set to a reference potential.

Abstract: A method and system for inspecting a rail by guided waves, the rail being instrumented by sensors. The method comprises the steps of receiving elastic wave measurements from one or more sensors, as a train passes, releasing energy as guided waves into the rail; and of determining a function representative of the impulse response of the rail and the sensors. Developments describe how to determine the existence, position and characterisation of a defect in the rail (e.g. fracture, incipient fracture, etc.), the use of inter-correlation analyses, correlation of the coda of correlations, Passive Inverse Filter, imaging techniques. Other aspects are described for exploring rail defects: sensor position and movement, acquisition time, sampling frequency, frequency filters, amplifications, techniques for learning during successive train passes, signal injection by transducers. Software aspects are described.

Abstract: The present invention relates to a method for sending information to an individual (11) located in the environment of a vehicle (10), the method comprising the following steps:



acquiring an image of the environment of the vehicle (10),
detecting, where applicable, at least one individual (11) on the acquired image,
determining a probability of collision between the individual (11) detected on the acquired image and the vehicle (10),
sending at least one item of information to the detected individual (11), the information sent depending on the determined probability of collision,
the steps of detecting, determining and sending being repeated, for the same individual (11), with subsequent acquired images as long as said individual (11) is detected on said images and as long as the probability of collision is greater than a threshold.

Abstract: A railway vehicle includes a car body having a shell frame surrounding an internal area suitable for accommodating passengers, and a power generator connected to an external side of the car body and including an outlet for discharging out a liquid produced during generation of electricity. A hydraulic system is in fluid communication with the outlet and receives at least part of the liquid produced during generation of electricity. The hydraulic system includes a first end portion connected to the outlet, a second end portion, spaced apart from the first end portion, for draining out from the hydraulic system the received liquid, and a third intermediate portion which is interconnected between the first and second end portions and is placed, at least partially, in the internal area of the car body, which is adapted to be heated before receiving passengers.
