Abstract
A rail-tie fastening assembly for connecting a rail having a rail flange to a tie comprising a rail seat assembly and a rail anchor. Th rail seat assembly is connectable to the tie and includes an anchor slot and a seat hook assembly. The seat hook assembly is adapted to extend a distance over an upper surface of the rail flange. The rail anchor includes an anchor hook assembly adapted to extend over on the upper surface of the rail flange in an assembled position of the rail anchor to the rail seat assembly. The rail anchor is insertable through the anchor slot in the rail seat assembly to the assembled position. The seat hook assembly is spaced a distance from the upper surface of the rail in the assembled position of the rail anchor to the rail seat assembly. The anchor hook assembly engages one side of the rail flange and the seat hook assembly engages the opposite side of the rail flange to restrain lateral movement. A base anchor is connected to the rail seat assembly and the base anchor is disposable in a cavity formed in an upper surface of the tie and the base anchor is secured to the tie, thereby securing the rail seat assembly to the tie.
