摘要： An electrical insulator for use with a rail fastening clip comprises a contact member providing on one side a substantially flat rail contact surface for contacting a foot of a rail and on the opposing side a clip contact surface for contacting a rail bearing surface of a bearing portion of the clip, the insulator also having retaining means for retaining the insulator on the clip in such a way as to allow rotation of the insulator about a longitudinal axis of the bearing portion of the clip. The insulator has stop portions for limiting such rotation about the longitudinal axis of the bearing portion of the clip to a desired extent. The clip contact surface of the insulator is convex, in a vertical plane which is perpendicular to the longitudinal axis of the bearing portion of the clip, such that, when the insulator is attached to a clip having a flat rail bearing surface, a contact region between the flat rail bearing surface of the clip and the clip contact surface of the insulator is linear. The insulator is rockable about the linear contact region within the extent defined by the stop portions such that, when the rail contact surface of the insulator contacts the surface of a rail foot, the angle of the rail contact surface can conform to the angle of the rail foot surface. A rail fastening clip, suitable for use with the insulator and of the kind driven onto a rail in a direction which is parallel to a longitudinal axis of the rail, has a bearing portion having a flat rail bearing surface, wherein a detent, extending laterally with respect to the longitudinal axis of the bearing portion, is formed in the flat rail bearing surface, at a location spaced from a free end of the bearing portion of the clip, for engaging a corresponding abutment surface of the insulator to be retained on the rail bearing portion of the clip.

摘要： A railway rail pad (1), for use beneath a railway rail in a rail fastening assembly as cushioning and/or electrical insulation, has first and second major faces (2, 3), the first face (2) having a rail seat portion (20) on which a foot of a railway rail sits when the pad (1) is in use, and side members (4A, 4B) attached to and extending from two opposite edges of the first face (2) of the pad (1). The side members (4A, 4B) are arranged so as to be located on respective opposite sides of the railway rail when the pad (1) is in use such that the rail seat portion (20) of the pad (1) lies between respective inwardly-facing wall faces (41A, 41B) of the said side members (4A, 4B). When the pad (1) is not under load and is placed so as to rest on a surface with the first face (2) of the pad (1) uppermost and part of the surface lying beneath the rail seat portion of the pad, an inclination angle (α1, α2) between the wall face (41A, 41B) of each side member (4A, 4B) and that part of the surface beneath the rail seat portion on which the pad (1) is resting is greater than 90°. When the pad is not under load, the first face is substantially convex in a vertical plane that is perpendicular to the longitudinal axis of the rail when the pad is in use.

摘要： A low maintenance rail seat has recess in the concrete tie and an abrasion plate that covers the floor of the recess and its sides parallel to the rail base. The abrasion plate includes ribs which seat in additional recesses in the tie to retard longitudinal movement. The anti-abrasion assembly preferably has four flanges which wrap around the top of concrete tie to prevent dust particles from entering and abrading the concrete rail seat. These flanges also wrap around the support shoulder for additional resistance to longitudinal movement. The components are designed to provide 8.5″ of lateral support along the side of the rail base while the traditional e clip fastener provides only 3″ of lateral support. The interlock feature between the anti-abrasion assembly and the concrete tie also minimizes relative movement between abrasion plate and concrete tie, which results in less concrete surface abrasion.

摘要： A system and an intermediate element for a system for fixing a rail for a rail vehicle onto a foundation. The intermediate element is arranged between an end section of a spring element and the rail such that the spring element exerts a retaining force on the rail by means of the intermediate element. The intermediate element has a supporting surface, on which the end section of the spring element rests during use, and a contact surface, with which the intermediate element sits on the rail during use. The intermediate element is elastically resilient in an active direction from the supporting surface towards the contact surface.

摘要： In a railway sleeper assembly, a pair of rail insulators (3) designed for use with a steel railway sleeper (1) which includes at the opposite sides of each intended rail location thereon a pair of openings (6) for receiving the respective stems (8) of a pair of shoulders (4), are each operatively disposed, when in use, between a foot of the rail (2) and the respective proximate shoulder (4). Each insulator (3) includes a member (11) which, when the insulator is in use, operatively extends below a top surface of the sleeper (1) and into the associated opening (6) so as to lie between the walls of that opening (6) and the stem (8) of the associated shoulder (4), thereby to retain the shoulder (4) in its operative position relative to the sleeper. The insulators (3), the shoulders (4) and a pair of rail clips (5) are preloaded onto, and are preassembled with, the sleeper (1) at a location remote from the track site, such that the entire assembly, with the rail clips (5) mounted in a preload position on the shoulders (4), can then be transported as a unit to the track site while the various components are retained on the sleeper (1) in their operative positions and are secure against falling off the sleeper (1) during transit of the assembly to the track site.
