The invention relates to a health status assessment method for a transport vehicle automatic or semi-automatic access device comprising at least one leaf suitable for being actuated by a kinematic chain including at least one motor supplied with electricity and having an associated angular position and/or rotation speed encoder and at least one switch. Said method includes steps, for at least one actuating cycle of the kinematic chain between a first and a second position among the open and closed positions and a second position, consisting of: during one said cycle, acquiring information relative to the kinematic chain comprising at least one piece of information representative of the electrical energy consumed by the motor, and/or position and/or speed information provided by said encoder and/or binary information indicating positions of switches, dividing said cycle into a plurality of functional segments based on said acquired information, calculating at least one descriptor value per functional segment, establishing a health status diagnosis comprising a degradation detection as a function of at least part of said calculated descriptor values.

A rail arrangement for rail vehicles furnished with flanged wheels. To reduce the risk of accident existing in connection with grooved rails, particularly for cyclists and pedestrians, a rail arrangement is provided including a. a rail (2) having a rail head (3), a rail web (4) and a rail base (5), the rail head (3) having a drive rail (6), a guide rail (7) and a rail groove (8) lying therebetween; and b. a filler profile (9) arranged in the rail groove (8).
