ABSTRACT:
A tie plate with posts is designed for easy insertion of the foot of the rail cooperates with pins through the posts to rigidly affix the rail to the tie plate and to railroad ties or roadbed. The posts may be made of flexible material in which case the rails are snapped into the tie plate. Alternatively the posts may be fabricated from hard plastics, ceramics, or metals, in which case the rails slide into the tie plates. The posts restrain the rail from lifting out of the tie plate or shifting laterally in the tie plate. Pins with fluted, or otherwise textured, surfaces are driven through guiding holes in the posts of the tie plate past the edge of the foot of the rail. The fluted edges of the pin serve to grip the rail. The pins are made of rigid or hard materials so that the pin will provide rigidity to the posts and also slightly deform the edge of the foot of the rail and thereby grip or engage the foot.
