Abstract: A rail clip for fastening railway rails to rail ties.

Abstract: A rail support assembly includes a rail tie, a rail with a rail base, a pair of support shoulders embedded in the rail tie and located on either side of the rail base, rail clips seated in the support shoulders and having a toe section lying on the rail base, rail insulators having an upper portion lying between the clip toes and the rail base, abutting the rail base, and a lower portion wedged between the rail base and the support shoulders, wherein each support shoulder includes: a rail face; a clip gateway through the rail face; a rail clip ramp from the rear of the shoulder to the clip gateway; and a retention ledge formed on the rail face on each side of the clip gateway. When assembled, each retention ledge is disposed above one of the rail insulators to prevent vertical movement of the respective rail insulators.

Abstract: Improved shoulder insulator for a rail seat assembly which enables the rail seat to be pre assembled at the rail tie fabrication plant into a preloaded position where a rail can be laid on the tie on site. On site the rail clips can be moved to the loaded position after the rail is placed in position.

Abstract: A two-part rail clip insulator (40, 50) for a tie and rail seat assembly that enables the seat to be pre-assembled at the rail tie fabrication plant into a preloaded position where a rail (2) may be laid on the tie (5) on site, the clips (30) being movable to the loaded position after the rail is placed in position.

Abstract: A rail fastening clip is used with a rail clip support having a rail clip slot of the kind used in K plates. The rail clip is formed from a U shaped member made of metal plate having a base and two arms tapered from the base to their tips, with the arms being bent inwardly beyond the base in a large arc and the tips are bent back toward the base and oriented for contact with the foot of the rail. The base is adapted to fit in the K plate slot of the rail clip support. The base of the clip has a leading edge remote from the arms that contacts the upper interior surface of the support slot to form at least a line of contact with the upper interior surface of the slot. The line of contact is about 6 mm. The design overcomes the problem of rotation of the clip within the support slot and is a more cost effective clip than that currently used with K plates.

Abstract: Improved rail clip support shoulders are less expensive than conventional shoulders.

Abstract: A rail seat which includes a) a rail tie b) a pair of rail fastening support shoulders mounted on said rail tie so that a rail can be held to the tie between said shoulders each shoulder having a a rail face and side portions on each side of said rail face extending away from the rail c) a rail pad adapted to lie on said tie between said shoulders which has a pair of projections extending parallel to the tie along side each side portion of each shoulder. The rail seat is adapted to be used with a deep post insulator and incorporates a rib on the support shoulder extending from each side portion against which a face of the rail pad projections abut to locate the pad in position to accommodate the post of the insulator. The rail pad projections are proportioned to prevent the pad from moving out of position under the creep load conditions present when rail cars pass over the rail seat.

Abstract: A concrete railroad tie is provided which utilises a tie 1 having a peripheral rib 5, 1 mm high, around the rail seat to contain adhesive 12 to bond a thick wear plate 8 to the tie. The surface of the tie is well below the top of the plate to reduce the penetration of abrasive materials between the rail pad 13 and the plate 8. This combination inhibits abrasion of the tie for the life of the tie.
