摘要： A rail clip assembly includes a rail clip, and a toe insulator having a pad with a diagonally oriented rail contact face, and an open-sided pocket receiving a toe end of a rail clip. The toe insulator includes a snap lock, structured to adjust between a locked configuration trapping a locating projection of the toe insulator in a bore in the rail clip, and an unlocked configuration.

摘要： A flat bar elastic rail clip in which the flat bar is turned back on itself so that one portion is longer than the other. The flat bar incorporates an opening in both portions to accommodate a rail spike that is held in the rail tie. This type of spike is usually used in combination with a concrete tie and a guide plate that seats on the rail seat of the tie. The combination of a shaped flat bar clip which is capable of providing both rail clamping and rollover protection configurations in combination with a guide plate and spike.

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 tool for removing rail clips of the kind which are applied transversely to the rail, which includes a pair of levers connected at a pivot point and being adapted to move toward or away from each other. Each lever has at its lower end, a rail clip engagement face which engage opposed sides of a rail clip seating transversely on the rail base. Each clip engagement face includes a clamp plate adapted to abut one side of the toes of the rail clip, an engagement pin adapted to engage one side of the rear portion of said rail clip, and a reaction pivot rear edge adapted to pivot about a point behind said rail clip. This arrangement allows the tool to be opened by moving the levers away from each other, placing the engagement faces on either side of the clip and then bringing the levers together so that the clamp plates compress the toes of the clip together so that the clip can be removed rearwardly from the rail clip support shoulder. When the toes are compressed the engagement pin abuts the rear curved portion of the rail clip and by pulling the levers away from the rail about the rear pivot base edge the rail clip is withdrawn from the base of the rail into the rail clip support shoulder.
