  • the invention relates to a method for aligning a track support slab with respect to a subsoil and a method for producing a slab track.
  • slab tracks are used in railway construction and typically have a solid rail superstructure, which usually consists of concrete or asphalt, instead of ballast or other loose materials.
  • Slab track is used, for example, on high-speed routes or in tunnels and is characterized by increased stability and durability compared to ballasted tracks.
  • slab tracks often consist of prefabricated concrete track supporting slabs, which are typically prefabricated in a factory and then joined together on site and connected to the rails. Then the track supporting slabs together with the rails are precisely aligned according to the specified route. For this purpose, the laid track support slabs are measured with the help of a measuring device and then aligned with the subsoil. This requires a team of several specialized people who work simultaneously on measuring and aligning a track support slab. Sometimes the position of a track slab needs to be remeasured or corrected. The manufacture of slab tracks is correspondingly time-consuming and expensive. A high level of precision is required when aligning track support plates so that trains can later travel the route at high speeds without any safety risk.
