ABSTRACT:
A box sleeper (1), characterized by a steel 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 closable at its ends by transverse plates (17 and 18) and has laterally projecting bearing flanges (13 and 14) for stockrail fasteners (28, 29), points-tongue slide chairs (30) and/or operating components of tip fasteners. The box-like sleeper section member (5) is associated with tip fasteners in the form of "latch fasteners" (33) comprising stationary guides (32) and movable latches (34), cam rods (34) and cam-rod bearings (37), all of which project into the upper part (31) of the box-like sleeper section member (5), whereas the bottom part houses the points-tongue slide rods (54), the tongue-monitoring linkage (45), heating rods (43) if any, and shock-absorbing elements (38). The open part (31) of the box-like sleeper section member (5) is closable on top by releasably mounted covers which can be secured to the bearing flanges (13 and 14) of the box-like sleeper section member (5) of the box sleeper (1).
