There is provided a superstructure device for a set of points. The device has a head side and a bottom side. The device delimits an interior space and is delimited on the head side by a slide plate supporting a tongue blade of the set of points. The device is delimited on the bottom side by a lower plate. A heater extends at some distance to the lower plate. The heater is arranged within the interior space. The interior space is thermally insulated at least towards the lower plate by insulation introduced into the interior space, whereby the heater is arranged between the insulation and a lower side of the slide plate.

A rail fastening apparatus fastens an inner stock rail in a railway slide chair assembly. The apparatus includes a base plate. The base plate has on one face a rail seat region on which the inner stock rail sits when the slide chair assembly is in use. A resilient rail fastening clip restrains the inner stock rail. A locating means locates the rail fastening clip in a first position. A loading means vertically deflects the clip so as to produce a load in a toe portion of the clip. A second locating means holds the rail fastening clip in a second position different from the first position such that the toe portion of the clip sits on a ramp of the loading means in a preload condition in which the clip does not bear on the rail

Monoblock reinforced concrete sleeper (10) for a solid track having reinforcement (12), wherein the reinforcement is exposed with a section underneath the base or bottom area of the concrete sleeper. In order to be able to predefine the anchoring capability of the concrete sleeper within a desired range and at the same time to ensure that circuit systems are not disrupted by the reinforcement, it is proposed that the reinforcement (12) is a section of a construction steel mesh for an N-sided polygonal column with N > 3 bent section of a construction steel mat, and the exposed section of the reinforcement is the support for longitudinal rods, and that the longitudinal and transverse rods of the construction steel mesh are electrically insulated on the outside.

The invention relates to a monoblock clamping concrete sleeper (10) for a fixed railway having reinforcement (12), with the reinforcement being exposed with a section underneath the sole or bottom surface of the concrete sleeper. In order to allow the anchoring capability of the concrete sleeper to be predetermined to the desired extent, it is proposed that the reinforcement (12) be a section of a structural steel mesh to form an N-corner column with N ᡶ 3 bent section of a constructional steel mat and the exposed section of the reinforcement be a rest for longitudinal rods.
