Technical barriers to the interchange and interoperability of trains, i.e. their ability to move along any section of the European rail network, continue to limit the competitiveness of the rail sector. There are currently more than 20 different signalling systems in Europe. Individual national networks usually have their own systems, whose performance (optimising the distance between trains and therefore track capacity) and level of security are very varied.

Expert article Ing. Ondrej Podolec on the topic Trends in tram track construction
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.
