ABSTRACT:
A rail fastening of the kind in which a rail, having a field edge and a gauge edge is fastened to a rail tie by a rail seat including a rail, a rail tie and a rail pad between the tie and the rail, a pair of rail clamp supports secured to the tie on either side of the rail and abutting the rail pad, and a rail clamp associated with each rail clamp support and each clamp having a portion secured in the clamp support and a portion bearing down on the rail flange. The rail pad electrically and dynamically insulates the rail tie from the rail and there is a rib provided on the field edge portion of the rail pad to reduce the intensity of the pressure on the pad under the field edge of the rail.
