ABSTRACT:
A system for fastening a rail to a foundation such as railroad ties or sleepers to form a railroad track. The system includes L-shaped inserts which are imbedded into the foundation and extending above it, supports which are laterally located with respect to the rails, and a fastening member or clip securing the rails. The main portion of each clip is mounted between the insert and the foundation, and one end contacts the upper surface of the supports. The other end of the clip contacts the flange of the rail, and has an offset lower surface which applies vertical and lateral pressure to the edge of the flange. The clip is made of a metal material and is a resilient spring having a multiple curved cross-section in order to apply compressive forces to the rail flange, the curved portions having undulating portions which make the various contacts.
