Permanent way superstructure with counter weights - which are used for counteracting sleeper lifting force

摘要

The railway track structure includes concrete sleepers (1,2) laid on an asphalt bed (18) to carry the rails (3,4), between which counterweights are laid to counter any tendency for the track to lift when the rails are under load. The counterweights (13) are also laid on the ends of the sleepers, and the total weight of sleeper and counterweight amounts to about 500 kg per m of track. Sound-proof elements (14) may be incorporated in the counterweights at the ends of the sleepers. ADVANTAGE - Low-cost system for sleeper a rail secure laying.
