One major European rail vehicle manufacturer has entrusted us with Solutions for the Railway Industry developing safety-relevant elastomeric components for bogies. Belotti After successful trial testing, these parts are now being installed in is building vibration-absorbing floors prototype vehicles. We expect series production to begin shortly. for the Milan metro and beyond, a co-development partnership 6 However, vibration isolation starts in the track superstructure: with sub-ballast mats, under sleeper pads or mass-spring systems. Liebherr-Transportation Systems We calculate, specify, test and produce track superstructure installs air-conditioning equipment solutions with profound expertise and with the same commitment on the roof with the help of APSOvib® that we devote to railway vehicles. 6 10 antivibration technology 10

Carriage construction: Elastic mountings absorb vibrations and noise The field of railway carriage construction is discovering the benefits of rigid but elastic and malleable polyurethane: As a floor ­mounting, the elastomer isolates vibrations and absorbs noise. Siemens is currently at work in Vienna fitting 190 carriages with elastomer strips. Angst + Pfister has built up specific know-how in affixing these safety-­ relevant parts, and also places this expertise at the disposal of other customers.

An aluminum plate is bonded to the polyurethane blocks. The adhesive bond is just as safety-relevant as the elastomer itself.

The best solutions for improving life cycle cost below the track 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.

Base plate pads For the elasticity of slab track systems, Angst + Pfister provides intermediate plates. They are installed between the rib plate and the concrete slab.

PRAG v3®: certified for improving high-speed rail LCC Total life-cycle cost (LCC) improvement is one key topic that drives R & D teams, especially in the capital intensive railway industry. Here it has been proven that under sleeper pads (USPs) can greatly improve LCC. For this reason, Angst + Pfister co-patented a state-of-the-art USP called the PRAG v3® that will be installed in the new high-speed TGV line connecting Nancy to Strasbourg.
