    摘要： The invention relates to a rail fastener for track systems, comprising a tensioning element (1) made of an elastic material, in particular hardened spring steel that in the assembled state is fixed in place between a retaining plate (3) provided on a sleeper (2) and a fastening anchor (4) such that the tensioning element exerts a retention force on the foot (5) of a rail (6) in order to hold the rail (6) in position, the tensioning element (1) being symmetrically aligned with respect to a vertically oriented plane of symmetry (7) that is perpendicular to the longitudinal axis (8) of the rail (6). According to the invention, the tensioning element (1) has two torsion legs (1a′ and 1a″), preferably extending essentially in parallel, in order to achieve stepped overload protection. The two torsion legs (1a′ and 1a″) are connected to one another on the side facing away from the rail (6) by means of a connecting section (1b), and a loop-shaped clamping section (1d′ and 1d″) is provided on each end (1c′ and 1c″) of the torsion leg (1a′ and 1a″) facing the rail (6). In the non-tensioned state of the tensioning element (1) the torsion legs (1a′ and 1a″) together with the connecting section (1b) lie essentially in a first plane (9), and at least a portion of the loop-shaped clamping sections (1d′ and 1d″) lie in a second plane (10). The second plane (10) is rotated about an axis (11) in relation to the first plane (9), the axis extending parallel to the sectional axis of the plane of symmetry (7) containing the first plane (9).

    摘要： A rail support forms an upwardly directed generally planar slide face, a longitudinally extending running rail secured to the support and having a foot. A longitudinally extending switch blade adjacent the rail is shiftable above the slide face between an inner position closely transversely juxtaposed with the running rail and an outer position transversely spaced from the running rail. A frame defines a longitudinal outer axis spaced transversely along the slide face from the running rail, a longitudinal middle axis between the outer axis and the running rail, and an inner axis between the middle axis and the running rail. Respective outer, middle, and inner rollers are carried on the frame and rotatable about the respective axes. The middle roller is axially offset from the inner and outer rollers and is of such a diameter that it radially overlaps the inner and outer rollers.

    摘要： A railroad switch actuator has a transversely extending box sleeper having a pair of ends, adapted to be secured to a pair of longitudinally extending fixed rolling rails, and adapted to slidably support a pair of longitudinally extending and transversely shiftable switch tongues. A switch rod extends transversely in the box sleeper, is connected to the tongues, is centered on a transverse axis, and is displaceable along the transverse axis to shift the tongues. A drive having an output shaft is supported on one end of the sleeper by a hinge for pivotal movement between a down position outboard of the one sleeper end and with the output shaft axially aligned with the switch rod and an up position between the sleeper ends.
