The original Rhaetian line in the municipality of Samedan has been lowered in order to separate the road from the railway. This will bring about significant improvements in traffic conditions in Samedan. A mass-spring system has been installed along a stretch of approximately 288 m in anticipation of possible future building work close to the track. Mass-spring systems are be-ing installed in areas where very stringent vibration protection requirements are in place. As the municipality of Samedan is located more than 1700 m above sea level, temperatures as low as -30 °C are not uncommon during the winter months. All the more reason to ensure that the mass-spring system works properly. Full-surface resilient bedding has been used. The expected natural frequency of the superstructure is in the region of 17 Hz. To allow trains to cross as smoothly as possible, ballast mats have been used to adjust the stiffness of the bedding at the points where the track crosses the mass-spring system.

The article looks on several more popular ride stability systems on the market that can improve suspension and handling, reduce wear of parts and help prevent accidents. Firestone's Ride-Rites has been available on the Mercedes Sprinter for years in Europe for recreational and utility purposes. Now, Ride-Rites have found their way to many light duty fleets in the states to help manage loads. Roadmaster Active Suspension's stability system was designed for any vehicle with a rear leaf spring suspension with up to one ton carrying capacity.
