THE SLEEPER (WOOD, STEEL OR CONCRETE)

The Purpose of Sleepers: transmission of loads from rail to ballast; maintaining correct gauge; angling the rail (1/20). Subjected to a whole lot of complex actions: vertical and horizontal efforts exerted by the rail flange on the upper surface of the sleeper; contact with the ballast, exerted on a narrow area at rail level, alternate dynamic bending at the centre part due to the passing traffic. It may happen that the sleeper is not correctly bedded, and there is a float of a few millimeters so that the passing traffic bangs the sleeper on to ballast.
