Abstract
An elastic rail fastening system for use with wooden rail ties in which the rail is seated on a rail plate which in turn is secured to the wooden rail tie by two pairs of spikes which also serve to support two rail clamps. The recessed portions of the spikes are adapted to receive the base portion of the rail clamp. The rail plate has an upstanding rib lying parallel to the rail flange and between each pair of spikes. The arrangement is such that the base of the rail clamp abuts the rail plate rib before it contacts the end of the recess which is adjacent the rail.
