The rail fastening system of SB W1 type is an optimized version of the SB type rail fastening system with PWE type rail pad which is designed and manufactured by Plastwil. Its main advantage is a high ability to attenuate impact load of 54%. This ability allows it to be classified into the category of high vibration damping in accordance with the requirements of EN-13481-2:2017.
The SB W1 type rail fastening system successfully passed performance tests. The PWE type rail pad has been used in Poland since 2006.
Characteristics and advantages of the rail fastening system of SB W1 type:
- shape and PWE type rail pad material significantly improves the resilience and the static and dynamic stiffness
- electric insulation between the rail foot and the sleeper reducing the dynamic interactions of rolling stock transmitted through the rails on the sleepers
- PWE type rail pad can be used in the rail fastening systems to all kinds of pre-stressed monoblock sleepers and turnouts and concrete turnout sleepers
