Under Sleeper Pads (USP) are tailor-made resilient systems designed to reduce track maintenance, increase the quality of the track and provide vibration mitigation by fixing elastic elements to the bottom surface of the sleepers.
The pads are designed to be attached during sleeper production by means of Pandrol USP Micro-Filament Fastenings (MFF®) technology.
