Rail Pads

Semperit is the go-to partner for challenging problems that require effective solutions. Rail pads distribute the load, reduce vibration and noise, and protect the sleeper and the ballast. No matter what type of rail pads our customers need – extruded or moulded, rubber or plastic – we have the solution for all requirements.

 

Basis

Our basic rail pads are made of rubber or plastic and are 4.5 mm to 9 mm thick. Their main purpose is to prolong the service life of the rails and the rail fastening by distributing the load to reduce shocks and vibrations on the rails.

Examples of basic rail pads  from Semperit (all in accordance with UIC 865-5-0):

  • NABLA rail pad  S90, S45 (4.5 mm grooved)
  • Zw 686a
  • Zw 687a

 

Standard

Our standard rail pads are made of rubber and are 4.5 mm to 10 mm thick. In addition to the basic rail pad properties, the standard rubber rail pad is usually designed for specific load deflection characteristics, which are certified in specifications such as SNCF IG04045 and DB 918 235.

Examples of standard rail pads:

  • Zw 900
  • Zw 700
  • SR or SD pads

Extra Performance

Our extra performance rail pads  are basically our standard rail pads with customised characteristics. We offer customised rail pads, which includes calculations, testing and producing prototypes for test installation at the customer’s site. Our SemperSilentPads are an example of an extra performance rail pad. These noise-reducing rail pads are up to 3 decibels quieter than standard rail pads. They have been tested on Semperit’s in-house test rig and are certified by INFRABEL and other track operators.
