Abstract: In a safe method of controlling the tilt of a rail vehicle traveling on a track, different sections of the track are allocated authorized tilt limit values representative of a safety gauge within which the train can tilt without risk of colliding with infrastructures near the tracks or a vehicle traveling in the opposite direction. All tilting of the vehicle is prohibited beyond authorized tilt limit values allocated to the track section on which the vehicle is located.

Abstract: The device for measuring a physical quantity associated with the rotation of a member includes a metal disc, integral with the rotating member, provided with at least one aperture forming a reference point. In addition, this device includes a fixed assembly for detecting the reference point, with at least one magnetic proximity detector and a part for checking that this detector is operating correctly, this being fixed outside the magnetic detector, without electrical contact or connection with the latter. The checking part has at least one conducting turn which surrounds an active end of the detector and is connected to modify its state by short-circuiting this turn or by supplying it with current.

Abstract: The bogie comprises an axle (14) rotatably mounted on a fixed underframe, and measurement apparatus for measuring a physical magnitude related to rotation of the axle (14). The measurement apparatus (34) comprises a metal disk (36) secured to the axle (14) and provided with at least one mark-forming perforation (40), and a fixed detection assembly (50) for detecting the mark, which assembly comprises at least one inductive proximity detector (52). Preferably, the disk (26) is fixed to a collector ring (26) of a current return assembly (24) for transferring the current coming from a motor of the bogie to the axle (14).
