A rail fastening apparatus comprises a shoulder member engaging on a side of the rail flange and a rail clip in the form of a resilient bent rod. The rod has limb portions that in the installed position extend transversely of the rail and inner and outer portions adapted to bear on the rail flange and on a bearing surface laterally outwardly of the rail, respectively. The bent rod is generally symmetrical about a vertical plane transverse of the rail, and the limb portions comprise an upper pair and a lower pair. The shoulder member has a reaction surface engaging one of the pairs of limb portions when displaced relative to the shoulder member as a result of upward pressure exerted by said rail flange and displacing this pair into contact with the other pair. This provides a load bearing cross section of increased depth providing increased strength and bending stiffness.
