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.

The invention relates to a railway superstructure comprising a track bed mat (10) as a continuous support of a track carrier system. The track bed mat (10) either consists of rubber recycling material having a polyurethane bond, or of polyurethane having a special specification, and has holes that run transversely to the mat plane such that a particular resilience effect with a static bed module between 0.005 to 0.08 N/mm2 and a dynamic bed module between 0.02 to 0.1 N/mm2 is achieved.
The invention relates to a sound insulating device on a streetcar rail (1), which is installed in a road and comprises chamber filling elements (3, 4). Joint compound (9, 10) is applied above the chamber filling elements (3, 4) between the rail head (11) and the road surface (8). The adhesive surfaces (21, 22, 23, 24) of the joint compound (9, 10) to the rail head (11) and to the road surface (8) are large enough to be durable. Filling bodies (30, 40) protrude into the space between the rail head (11), road surface (8), and top side (31, 41) of the chamber filling elements (3, 4), but without impairing the size of the boundary surfaces (21, 22, 23, 24) of the joint compound body (9, 10) or triggering notch effects.
Sound-damping device on tram rails (1) having chamber-filling elements (2) made of sound-damping material, the side faces (36; 136) of which have engagement cutouts (33, 43) near to the end faces (24; 34; 44), wherein clamp-shaped connecting elements (5) engage with clamp projections (51, 52) into the engagement cutouts (33, 43) and clamp adjacent chamber-filling elements to one another.

Sheathed railway rail having an outer casing (4). Electrically insulating box profile sections (40) are fitted around rails (1), with filling bodies (2, 3), in a water-tight manner. The sheathed rail (1) can be attached to the track body, without clamps and threaded bolts, solely by being cast in concrete

E01B 21/00 - Track superstructure specially adapted for tramways in paved streets
The invention relates to a rail bed for a rail (1) of a railway on an essentially continuous substructure (9), said rail bed comprising damping elements (10, 20, 30, 40, 50) arranged continuously between the base (4) of the rail and the substructure. The invention also relates to the use of a pre-stressed, pre-fabricated damping element for a continuous rail bed, the damping element comprising a layer which consists of metallic or organic elastic materials and can be swaged under a maximum load of between 0.3 and 1.9 mm. Said damping element is arranged on a substructure extending in the longitudinal direction of the rails beneath the base of the rails. A casting compound (7, 7') is provided between the rail head (2) and the surrounding construction material (P, E). The damping elements have at least one elastic layer (13, 23, 33, 43) and a vertical initial stress, the initial stress being selected in such a way that the sinking of the rails under a defined load exerted by the vehicle running thereon is less than that enabled by the permanent elasticity of the filling compound.

Disclosed is a machine for cutting and punching chamber filling elements made of plastic-bonded rubber granulate. Said machine comprises a chassis (1) for displacing the machine at construction sites, a guiding column that is fastened to the chassis (1), a tool support carriage (3) which is movable along the guiding column (2), a drive unit (4) for moving the tool support carriage (3) back and forth, a workpiece bench (5) for supporting the workpiece (7) that is to be machined, and a cutting and punching tool (6) which is replaceably attached to the tool support carriage (3).
