A block boot (1) that has a rectangular ground plan, a bottom (5), and four side walls (2, 3). On the interior of the side walls (2, 3), ribs (10, 15) extending in parallel to the bottom are arranged. At least one of these ribs (10, 15) tapers from the respective side wall (2, 3) toward the interior of the block boot to a free end having a vertex line (24, 25). This block boot is simple to manufacture and offers improved properties with regard to static and dynamic rigidity in operation.

A fastening system for track rail includes a molded support block, and a direct fixation fastener positioned upon an upper side of the molded support block. The direct fixation fastener includes a metallic frame and a non-metallic overmolded jacket. Clamping fasteners of the fastening system are structured to engage with retention elements integrally molded in a concrete matrix material of the molded support block to clamp the direct fixation fastener to the upper side within a range of lateral positions.

A band adapted for use as a seal around an upper edge of a boot adapted for holding a block to which a rail is fastened, includes an elongated body having an outer face, an inner face, a first end and a second end. The first and second ends of the elongated body are secured to each other to form the band. An inner face of the elongated body is smooth and an outer face thereof includes a plurality of longitudinally spaced ribs. The ribs extend from the first end of the band to the second end thereof. The elongated body is made from an electrically insulating elastomeric material.

A sleeper block unit including a sleeper block and a sleeper shoe that surrounds the latter in its lower area. In the area of the upper edge of the side walls (9) of the sleeper shoe, a surrounding sealing collar (14) of an elastic material is arranged which sealingly connects the sleeper block to the sleeper shoe. The sealing collar (14) includes an upper edge section (15), a lower edge section (16), and a lateral section (17) arranged therebetween. In the area of the upper edge of the side walls (9) of the sleeper shoe (3), a surrounding bead (11) is externally arranged which is sealingly overlapped by the lower edge section of the sealing collar (14).

A ballastless track system comprises a base; a track slab arranged above the base; a poured-field layer arranged between the base and the track slab, the poured-field layer being formed by filling self-compacting concrete, emulsified asphalt cement mortar or resin mortar, and the inside of the poured-field layer being of a steel bar structure; a connecting piece, the first end of the connecting piece extending into the track slab, and the second end of the connecting piece extending into the poured-field layer; and two rows of rail-seat arranged on the track slab in parallel; and rails arranged on the rail-seat. The ballastless track system is high in reliability, good in durability, and easy in construction and maintenance.

A track rail fastening system includes a direct fixation fastener assembly having a direct fixation fastener, and a laterally elongated support block. Fastener holes for receiving fastener-clamping fasteners, and fastener holes for receiving bracket-clamping fasteners, are formed in the support block. The respective sets of fastener holes are arranged in different anchor patterns. Fastener-clamping fasteners are received in one of the sets of fastener holes and claim direct fixation fastener to the support block. Bracket-clamping fasteners clamp a third-rail support bracket to the support block, and are received in one of the sets of fastener holes. The third-rail support bracket is cantilevered to the support block.

The invention relates to a ballastless track section for a rail vehicle, said section being fastened to a platform (10) and comprising: a prefabricated concrete track slab (20, 120) comprising two stringers (21, 22); a rounded bearing surface (21c, 22c) borne by an underside of each stringer at each longitudinal end and having a curvature, the center of curvature of which is the top of a rail (21b, 22b) borne by the stringer; a prefabricated support pad (30, 130) for supporting each longitudinal end of the slab (20, 120) and comprising at least two support bases (33, 34) for the two stringers of this longitudinal end of the slab, each base (33, 34) comprising at least one shim (33a, 34a) of predetermined thickness supporting said rounded bearing surface (21c, 22c) of the stringer of said slab facing this base.
