Abstract: The invention relates to a rail attachment system (1) for attaching a rail (2) to a concrete support slab (3a) or a concrete sleeper (3b) or to a steel structure comprising an intermediate plate (4), a rail attachment plate (5) with angle guide plates (6, 6b) arranged thereon, at least two first tensioning clamps (7a) for clamping the rail foot (2a) to the rail attachment plate (5) as well as screws (9) and/or ankle bolts (10) and at least two second tensioning clamps for screwing the rail attachment system (1) to the underlying surface, characterized in that an elastic intermediate layer (8) is arranged between the rail (2) and the rail attachment plate (5), and the intermediate plate (4) is composed of a highly elastic material and/or comprises a steel plate (4), at least two second tensioning clamps (7b) for clamping the rail attachment plate (5) to the substructure, preferably via the intermediate plate (4), wherein the first and second tensioning clamps (7a, 7b) are embodied in a highly elastic fashion w

Abstract: In a device for supporting a rail fastened to a sole-plate resting on an anti-vibration pad, the sole-plate is urged towards the supporting structure by at least one adjustable prestressing resilient device acting on the sole-plate so as to apply a defined prestressing force to the anti-vibration pad. Each prestressing resilient device includes a threaded bolt, an adjusting nut and a vertically acting spring assembly which comprises a first spring having a first stiffness, a second spring arranged round the first spring and having a second stiffness higher than said first stiffness, and a device for retaining said first and second springs in such a way that each of said springs is able to act independently from the other one.

Abstract: A rail retaining device has a shoulder that has a body portion, a hook-in leg portion and a bearing portion, and adapted to be pivoted from an installation position. To install the device, the body portion is inclined relative to a plate form tie, and the hook-in leg portion is inserted through an aperture in the tie. The shoulder is moved to an erected position, in which the hook-in leg portion engages an underside of the plate tie and the bearing portion engages on an upper side of the tie. A clip is located relative to the shoulder by engagement with the shoulder is inserted between a side surface of the body portion and a rail flange and retains the shoulder in an erected position.

Abstract: A railway rail anchoring device, for use with a railway rail-fastening clip which is approximately M-shaped in plan and has first and second leg portions and a rail-bearing portion, comprises a base member and first and second clip-retaining members connected together by the base member such that the first clip-retaining member is spaced apart from the second clip-retaining member so as to define between the first and second clip-retaining members an opening for receiving the rail-bearing portion of such a clip.

Abstract: Concrete railroad stringer assembly for securing a railroad track comprising supports imbedded in the stringer and having a bow-shaped part extending above the stringer. The supports either are equipped with an abutment made of synthetic material or are made of ductile material forming itself an abutment for the railroad track. The supports are equipped with or intended to receive securing straps for securing the railroad track on the stringer.
