Definitions

• the invention relates to a system for fastening a rail, in particular a rail of a switch, on an inelastic solid and just trained underground.
• Substrates formed of concrete or similar solid, inelastic materials so-called “solid lanes”, have the advantage, in particular on such routes, which are traveled by trains at high speed, that they due to their high inherent rigidity in each case occurring high loads during the crossing without being able to safely absorb the risk of undue deformation of the rail and ground.
• the rail is usually supported by an elastic intermediate layer on the ground.
• Spring elements acting from above on the rail foot so-called tensioning clamps, press the rail against the solid ground with a defined contact force.
