Ballastless track

Production of insulated joints Protection of the tracks Ballastless track The negative impact of the ballast on the service life of the track led to initial designs of ballastless track The ballast is replaced by sub-layers of concrete or asphalt which unlike ballast have no or only slight plastic deformation and the rail Get price

General principles

The vertical forces are carried into the rails and the sleepers as ballast pressure σ B into the multi-layer system ballast-subgrade-subsoil and distributed and dissipated into it Under the vertical wheel force or wheelset force P = Pstat+ Pdyn the rail or track experiences an elastic deformation s (spring deflection) Get price
