Abstract
Resilient railroad fastener system comprising an elongated shoulder member and spring clip to be so applied and combined with the shoulder member as to create a toe load applied downward to the rail; the shoulder member having a reaction surface to be engaged at a first angle by one arm of the spring clip and the shoulder member being configured with a capturing surface to capture the other spring arm while cocking the spring clip at an angle to the horizontal when the spring clip is applied to the shoulder member; whereby when installed the spring clip has a toe load impressed thereon which is the vector sum of the clip load and shoulder reaction.
