Abstract
An elongated rail fastener apparatus for use near an obstacle such as a guard rail, or other location where space is restricted. The fastener preferably extends past the obstacle and is provided with a shoulder having at least one elevated notch, positioned to allow installation of the clip with a vertical and lateral movement, and without the application of a large force perpendicular to the rail. A U-shaped embodiment of the fastener is also described.

A rail fastening apparatus to restrain a rail flange on a tie plate, comprising:
- a first retainer mounted on the tie plate near the rail flange;
- a first shoulder mounted on the tie plate at a distance from the first retainer, the first shoulder comprising a first notch in a side surface of the first shoulder, above an upper surface of the tie plate;
- and
- an elongated resilient fastener having a heel end and a toe end, and a body length between the heel end and the toe end that is greater than the distance;
- wherein the elongated resilient fastener fits through the retainer and the heel end fits in the first notch on the first shoulder such that the toe end of the elongated resilient fastener restrains the rail flange;
- and
- wherein the heel end is inserted into the first notch by lifting the heel end and moving the heal end laterally to the first notch.
