Abstract
A superstructure arrangement for a track comprising a rail fastened to a securing device such as a ribbed plate which is disposed above a concrete sleeper, with an intermediate layer extending between the sleeper and the securing device. The rigidity of the intermediate layer is variable and rated so that at the maximum permissible stress in the rail, caused by bending under wheel lead, the elastic property changes to substantially non-elastic.
