Abstract: 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).

Abstract: The sleeper block unit (1) for railway track systems consists of a sleeper block (2) and of a sleeper shoe (3) that partly surrounds the sleeper block (2). The sleeper block (2) has a head portion (4) and a base portion (6), the head portion (4) extending beyond the base portion (6) in length and in width, thus forming a step (10). At the upper edge of the sleeper shoe (3), a surrounding, upwardly and outwardly extending sealing lip (14) that lies against the step (10) is arranged. As a result, during vertical movements of the sleeper block (2) in the sleeper shoe (3), the sealing lip (14) is deformed substantially vertically in the elastic range rather than rubbing against an outer wall of the sleeper block as in known sleeper block units. In this manner the sealing lip is subject to reduced wear so that the sealing effect is maintained for a longer period and the sleeper block unit (1) has a longer lifetime.

Abstract: In a section of a ballasted track that extends over a plurality of crossties, ballast is removed and crossties are removed. Crosstie blocks mounted in concrete slabs are inserted, lifted, and fastened to the rails. The rails are supported by temporary, vertically adjustable supports and adjusted. In an area that extends over a number of concrete slabs, infill concrete is filled in from the underground up to at least part of the height of the concrete slabs, and after the infill concrete has hardened, at least a part of each of the supports located between two respective concrete slabs is removed. The method allows the conversion to be carried out without changing the position of the rails. After the placement of the supports, the track is immediately operable again so that the relevant section need not remain closed until all method steps are completed.

Abstract: In order to produce a slab track for rail vehicles with an emergency pathway (12) for road vehicles, a prefabricated track section with rails (8) and sleepers (5) is supported and positioned on a substructure (1) by means of a supporting and aligning device (4). Subsequently, a track slab (10) is produced by casting in the sleepers (5). The part of the sleepers (5) that projects from the track slab (10) and the rails (8) are separated by formwork elements, and an emergency pathway (12) is applied to the track slab (10) by casting.
