Abstract
A rail fastener assembly includes a restraining block to resist rail overturning and which is disposed atop a tie plate having a raised shoulder adjacent a rail seat section. The curved upper surface of the shoulder is engaged by a mating curved lower surface on the block to position a lip portion on the block in overlying relationship to the rail base flange. Means vertically extend downwardly from the block and cooperate with two spike holes formed through the tie plate shoulder to secure the block relative the tie plate. A rail anchor may be attached to the rail base adjacent the tie plate to provide a complete rail-to-tie fastener assembly.
