Abstract: The invention relates to fixing means for fixing railway lines to sleepers or stretches of track, comprising an elastic rail clip (51) and a clip anchor element (31). According to the invention, the elastic rail clip (51) has retaining elements that can be inserted into the clip anchor element (31) and guided into the latter by being rotated about a rotational axis (D) and at least one pressure bow (52), which can be brought into pre-tensioned contact with the foot (24) of a railway line (21), when the elastic rail clip is rotated (51) about the rotational axis (D) in relation to the clip anchor element (31). The elastic rail clip (51) has essentially annular clip bows (55, 56) that act as the retaining elements and the clip anchor element (31) has guide elements (34) that are concentric with the rotational axis (D).

Abstract: The railroad highway crossing panel fastening system includes a series of dowel pins, spring clips and hanger/hanger bars. The dowel pins are inserted or cast into the ends of each crossing panel in a plane parallel to the base of the rail and are positioned from the edge and top of the panels in such a manner as to accomodate varying rail sections. Each dowel pin protrudes beyond the end of the panel a sufficient distance so that when the spring clips or hangers are attached to them and engaged they secure the crossing panels to the track structure enabling highway traffic to pass over the railroad tracks in a safe manner.
Abstract: The rail anchor system includes two pins and two clips. Each pin extends through a horizontal transverse bore in a cross-tie. The pins have extensions at each end exposed on both sides of the cross-tie and the bores are parallel to and substantially within the outer edges of the bottom flange of the rail which sits on the cross-tie. Two resilient clips form a part of the system. Each clip has a looped section, a hooked extension extending from one end of the looped section and a lever extension extending from the other end of the loop section. A clip is used on each side of the tie with the loop sections engaging the pin extensions of opposite pins and the lever extensions being locked by opposite pins when the respective hooks are in engagement with the cross-tie.
