SCHWIHAG offers consultancy, development,
construction, production, supply and service
for rail fastening systems and the following


  • standard railway lines (20.5 t axle load – 30 t axle load)
  •  high-speed railway lines (up to 20.5 t axle load)
  •  heavy freight transport (over 30 t and up to 50 t axle load)
  •  underground systems (12 t – 13 t axle load)
  •  metro systems (16 t axle load)
  •  tramways (6 t – 10 t axle load)
  •  industrial railway lines (22.5 t – 50 t axle load)

for the following track systems::

  •  ballast permanent way with concrete sleepers
  •  ballast permanent way with wooden sleepers
  •  ballast permanent way with steel sleepers
  •  paved concrete track
  •  bridge beams (steel bridges)

independent of:

  •  track profile and track gradient
  •  sleeper geometry
  •  routing (e.g. tight radius, high gradient)


SCHWIHAG fastening systems SFS are:

  •  proven standard systems
  •  new developments customised to your specific requirements
  •  adaptations using optimised components, e.g. new spring clips for existing sleepers
  •  components made to specifications for complex installations
  •  systems with special surface protection for SFS components in critical environmental conditions
  •  systems with highly effective sound/vibration insulation
  •  systems for transition areas, e.g. tunnels and bridges with a high level of relative motion between rail and sleeper
  •  supplied unconnected
