ABSTRACT:
An arrangement for fastening rails to sleepers includes guide plates (10) disposed to the sides of each rail and elastic clips (20), which may be pressed onto the respective guide plate (10) and onto the foot of the rail by means of bolts (30) anchored in the sleepers, the guide plates (10) having on their upper side in the installed position a rib (13) extending parallel to the rail, on which a part (21) of the elastic clip may be brought to seat as a boundary for the stress path.
In order that the guide plates (10), when made also from plastics, may safely carry without damage the forces exercised by the clips (20), even when there has been an excessive torque on the bolts (30), each rib (13) of the guide plate (10) has a reinforcement (14) in the seating region of the clip (20).
