The proposed device is a sleeper for railway track systems, suitable for incorporation in the track near points, more particularly near the drives and the associated tip fastenings for the points-tongues, which are adjustable via slide rods. The aim is to replace expensive manual operation by high-tech mechanised track construction using completely mechanised track-tamping machines, even near the points-tongue drive and the associated tip fastenings. To this end, the proposed sleeper is a box sleeper (1), characterised by a steel trough or box-like sleeper section member (5) which has a cross-sectional width (15) and a cross-sectional height (16) matching that of a normal concrete or wooden sleeper and has an open part (31) on top and is optionally closed or closable at its ends by transverse plates (17 and 18) and has laterally projecting bearing flanges (13 and 14) for stock-rail securing means (28, 29), points-tongue slide chairs (30) and/or operating components of tip fastenings, and the trough or box-like sleeper section member (5) is associated with tip fastenings in the form of "latch fastenings" (33) comprising stationary guides (32) and movable latches (34), cam rods (35) and cam-rod bearings (37), all of which project into the upper part (31) of the trough or box-like sleeper section member (5), whereas the bottom part houses the points-tongue slide rods (44), the tongue-monitoring linkage (45), heating rods (43) if any, and shock-absorbing elements (38). The open part (31) of the trough or box-like sleeper section member (5) is closable on top by releasably mounted covers which can be secured e. g. to the bearing flanges (13 and 14) of the trough or box-like sleeper section member (5) of the box sleeper (1).
