Improvement to Rail Clips
Rail Clip Assembly A rail clip assembly is disclosed herein. The rail clip assembly, in accordance with an embodiment of the present subject matter, comprises a base body attachable to a support surface, wherein the base body defines a cavity at an underside thereof. The base body comprises a first wall that is adjacent the rail when the base body is secured on the support surface. A depression or a recess is configured on the first wall, and a substantially horizontal slot is configured on the base body extending toward the first wall. The assembly further comprises a top body assemblable on the base body. The top body comprises a rail abutting portion that defines a substantially L-shaped surface to abut the rail, and a slot configured on the top body. The assembly further comprises a screw for assembling together the base body and the top body, wherein the screw may be any standard WO 2020/046771 A1 screw with a polygonal head such that a corner of the screw head is fitted inside the depression or the recess in an assembled configuration thereof.

Rail fastening device
A rail fastening device comprises a clip (10) having a base (11) and a nose (12) for engaging a rail flange (F). The base (11) comprises circular aperture (14) in which a circular cam (13) is rotatably mounted, the cam (13) being provided with an eccentric aperture (24) for receiving a ground anchor (25), the cam aperture (24) being radially offset from the rotational centre of the cam (13) to define a cam lobe (15). The cam (13) may comprise a ramped circumferential shoulder (18) to engage a complementary shoulder (21) inside the base aperture (14) such that any rotation of the cam (13) under the applied load of the rail causes the cam (13) to move axially of the base aperture (14) thereby tightening the engagement of the anchor (25) on the cam (13) and preventing movement of the clip (10). The degree of rotation of the cam (13) may be limited so that it can only turn in the tightening direction under load.

RAIL FASTENING DEVICE
A rail fastening device (10) comprises a clip 16 and a washer (17) for fastening to a rail support (12) by an upstanding bolt 14 having a nut (15), which can be tightened to lock the device (10) in position. The clip (16) and washer (17) comprise respective apertures (18), (19) for receiving the bolt (14). The washer (17) is adapted to rotate as the nut (15) is tightened until a formation on the washer (17) abuts an upstanding formation (24) on the rear of the clip (16) at point A, whereupon continued tightening of the nut (15) causes the washer (17) to pivot at point A around an offset axis, so as to bring the bolt (14) into contact with a front surface (18F) of the clip aperture (18). Further tightening of the nut (15) pivots the washer (17) to a point where any displacement force applied to the clip (16) by the rail is applied directly to the bolt (14) and not to the washer (17). In this manner, the risk of the washer failing, or bolt (14) bending is avoided.

Holddown assembly for railway rail
A holddown assembly fastens a railway rail to a transversely extending hollow sleeper formed with a vertically throughgoing hole. An upwardly projecting lateral brace element is provided on the sleeper offset from the hole, and the assembly has a body fitted between the rail and the brace element and transversely bracing the rail against the brace element. An anchor of the assembly is engaged through the hole, projects upward from the sleeper, is transversely shiftable in the hole, and bears upward on the sleeper. A spring clip is pressed by the anchor down against the rail and presses the rail down against the metal sleeper.

Device for fastening trackside modules to rails
The invention relates to a device for fastening trackside modules to a rail having a base and a head. The device includes two clamps that are clamped on the base of the rail with the use of a mechanism that extends under the base of the rail. At least one of the clamps is movable. A bracket is fastened to at least one of the clamps and a trackside module is fastened next to the head of the rail. A pair of brackets is fastened with the use of fasteners to surfaces of each of the clamps. The brackets extend transversely to the longitudinal axis of the rail and at least one upwardly extending section is fastened using second fasteners to at least one of the brackets outer side surfaces. At least one trackside module is fastened to an upper end region of at least one upwardly extending section.
