The track design of tramways has historically gone through various stages, as in the case of railways and stages of development. The fundamental difference between urban rail and conventional railway track is the amount of axial pressure that the track superstructure and substructure have to bear. On railway lines, the vertical static load per axle is up to 22,5 tonnes, the load on urban railways is approximately 11 to 12 tonnes. The load values are determinant for the structural composition of the track components.
