摘要： A rail (11) for electric railways, in particular tramways, is elastically embedded in a substructure (40). The electric insulation of the rail (11) with respect to the substructure (40) is adhesively applied to the rail surface by spraying in the form of an elastic, flexibily curing and volume-compressible and shear-flexible layer (20). The total thickness (25) of the layer (20) is at least 4 mm. The outer face (30) of the layer (20) is structured in such a way that it is adhesively joined with the substructure by bonding or a form-fit connection.

摘要： Disclosed is a rail vibration absorber, comprising an elastic element (4), a mass (3) and at least one coupling frame (2). The coupling frame (2) has the same surface shape as a non-working surface coupling portion of a steel rail. The coupling frame (2) comprises at least one vibration absorption cavity (100). The mass (3) is at least partially disposed in the vibration absorption cavity (100) of the coupling frame (2). The elastic element (4) is arranged between the mass (3) and a wall of the vibration absorption cavity (100). The rail vibration absorber has a simple structure, stable performance and good weatherability, and can effectively slow wear to the steel rail and prolong the service life thereo£

摘要： One aspect of the invention provides a rail arrangement in which a rail is releasably supported in an inner shell, and the inner shell and rail are received within an outer shell. This provides flexibility in that the design of the inner shell can be varied to provide different relative positioning of the rail with respect to the outer shell. Thus, the inner shell can be used to take account of sinking of the outer shell, which is typically cast into the rail foundations.
