Mirosław Romański talks about SB resilient feet, i.e. fastenings commonly used in recent years on railway lines. It is worth adding that this mounting has been patented in Poland. Its origins date back to 1979, and in the following years it was perfected and disseminated. Improving the technical parameters resulting from the tests and the use of these fastenings resulted in its subsequent versions - from the SB3 and SB4 elastic clamp to the SB7 fastening. Although Western countries were initially cautious about this solution, after they obtained the appropriate certificates, the SB type of fastenings found its application in various countries. Currently, it is already the basic solution used in the construction of the track.
