Angst + Pfister – Your Partner for Technical Solutions for Track Substructure

Angst + Pfister’s track solutions increase effectiveness and efficiency in safety, performance and life cycle cost. Across Europe over the last 30 years, heavy tracks, high-speed rails as well as tramway tracks have all been equipped with Angst + Pfister solutions. We aim to preserve track design, reduce vibration and track life cycle cost. Our experts co-design and produce a vast array of products, to meet your exact specifications, from a wide range of materials. Under Sleeper Pads (USP), Mass Spring Systems (MSS) and Under Ballast Mats (UBM) are three of our expert solutions.

Mass Spring System Angst + Pfister provides easy-to-apply, long lasting and highly economical solutions to effectively damp track vibrations. Our Mass Spring System is ideal for tramway, underground and other low-frequency vibration damping applications. The bearings are available in both mixed cellular polyurethane and high-quality recycled rubber granulates within three main forms: • Full surface mats solutions can reduce by 25 dB the mechanical noise level for systems with a natural frequency between 14 to 25 Hz • Strip solutions are a perfect fit with pre- manufactured tracks and on-site concrete track pouring. Efficiency starts for natural frequencies from 8 to 15 Hz • Pads solutions are preferred for natural frequencies between 5 to 12 Hz, and can also improve the noise reduction by 30 dB

The rail groove filler is used to close the rail wheel groove of urban rails and tracks and thus eliminate danger points for both, pedestrians and bicycles.
