摘要： A rail retaining device has a shoulder member for bearing on a lateral side of a rail flange. The shoulder has a downwardly facing abutment surface. A rail clip is of bent rod symmetrical about a vertical plane. The clip has an inner portion bearing on the flange, intermediate limb portions reacting with the abutment surface and flexed resiliently downwardly in the installed position, and an outer portion connected to each intermediate limb portion and extending arcuately outwardly and downwardly to a lower portion adapted to bear on a bearing surface.

摘要： A railway tie pad is provided with studs that are either offset from opposed positions from each other, on opposite sides of the pad; or are of differing heights. Pads with these features are capable of being more efficient in isolating ties and rails from shock loading, and in accommodating varying loads with differing cushioning characteristics.

摘要： 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.

摘要： A rail tie plate suitable for attachment to a wood tie has a pair of upstanding abutment members to accommodate a rail flange, each having an upwardly facing lower ramp surface inclining from a laterally outer side of the abutment member upwardly inwardly to a laterally inner side to facilitate insertion of a rail clip. The tie plate tapers in thickness and has an upper side canted with respect to the lower side. The lower side is provided with wedge shaped projections that tapers laterally in the same direction as the plate and have an end face making an angle no greater than 90° with respect to the lower side.

摘要： A steel tie for incorporation in rail track has a horizontal rectangular plate for connection transversely of the rail to restrain vertical rail movement. The longer sides of the horizontal plate terminate in downwardly and outwardly inclined margin portions for capturing ballast. A web member extends vertically on the underside of the plate member and parallel to and centrally of the longer sides of the plate and serves to restrain longitudinal rail movement. Curved ballast engaging plate members are connected on the underside of the tie to provide lateral stability. The plate members are detachable and replaceable with smaller or larger members to provide a smaller or greater ballast engaging area. The lower edge of the vertical web has a thickened portion to carry stresses. Rail fastening devices consist of a pair of opposing longitudinally extending shoulders adapted to accommodate the rail flange between them. Each shoulder has a downwardly facing abutment surface, and a resilient rail clip has an intermediate portion that bears upwardly on the abutment surface, an end portion that extends inwardly from the abutment surface and bears resiliently on the upper side of the rail flange.
