The compressible sealing element (1) comprises at least one piece made of a resilient foam (17). This foam has an open-cell content of at least 50% and has such a hardness that it requires a force of less than 2000 N to compress the sealing element (1) per meter length thereof to such an extent that the volume of a rectangular cuboid circumscribing the sealing element is reduced by 40%. The sealing element comprises a water-impermeable cover layer (18) which extends at least over its top surface. The sealing element is intended for filling at least partially the gaps between the stock rails (13) and the switch rails (12) in a railway switch to prevent the switch from being blocked in particular by snow. Advantages of the new sealing element is that it can easier be inserted in these gaps and that it has a smaller effect on the force required to close the switch so that it can also be applied closer to the free extremity of the switch rail (12).

A maintenance vehicle has side walls for creating a work space, delimited by the same, for working personnel situated on a track. The side walls are arranged on a vehicle frame and configured to be distanced from one another in a transverse direction of the vehicle. For treatment of a track section situated within the work space, an industrial robot is arranged on the vehicle, having at least three motion axes, media couplings for energy supply as well as a tool coupling for selective connection to a track treatment tool.

A health status assessment method and system for a transport vehicle automatic or semi-automatic access device is disclosed. The health status assessment system has at least one leaf actuated by a kinematic chain including at least one motor having an associated angular position or rotation speed encoder and at least one switch. The health status assessment method includes steps for analyzing at least one actuating cycle of the kinematic chain between a first and a second position wherein, during one said cycle, information is acquired representative of the electrical energy consumed by the motor, or position or speed information provided by said encoder or binary information indicating positions of switches. The method further includes dividing said cycle into a plurality of functional segments based on said acquired information, calculating at least one descriptor value, and then establishing a health status diagnosis of the health status assessment system.

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.
