They are the only connection between steel rails and railway sleeper, railway fasteners has to bear both vertical and longitudinal forces when the train is passing by. Furthermore, vibrations are generated due to the uneven and unstable height of rail wheels, steel rail and rail sleepers. High-frequency vibration rate of rail could reach 60000 cycles per minute, and that is measured at a moderate speed of 100 kmph.

Rail Fastening System on Concrete Sleeper

In fact, the rail fasteners has to be checked regularly for safety issue, for train passes each time on the rail sleepers, it might lead to loosen of rail bolts, fish bolt break, fish plate break, etc, which are caused by constant pressure and high rate of vibration.
