Abstract
Abstract The cross-ties or sleepers (8) between two rails (4) of a track installation consist of a mixture of sand, gravel or rubble as well as elastomer parts which are bonded using a synthetic resin binder. The proportion of elastomer can be greater at the bottom of the sleeper (8) than in the remainder of the sleeper element. The rail (4) is clamped on the sleeper (8) with two clamps (5) by means of nuts (6) and by means of screw bolts welded onto a steel reinforcement (9). Thus, elasticity and damping characteristics similar to those found in wooden sleepers are achieved. <IMAGE>
