The Plasser Dynamic Track Stabilizer PTS90C is designed to apply specific and controlled stabilizing forces into the track structure at continuous speeds. Traffic loads subject the track to irregular and uncontrolled settlings which result in premature or accelerated track deterioration. The purpose of the Plasser Dynamic Track Stabilizer is to provide a controlled and accurate settling of the track after maintenance work has been performed. Stabilization extends the life of corrected track geometry - an important factor for today's high speed, high tonnage and passenger railroads. Dynamic track stabilization is a combination of horizontal vibration and vertical load applied to the track. This process accelerates the initial track settlement immediately after maintenance work. A deliberate and accurate settling is achieved with the aid of a reference system. Dynamic track stabilization consolidates the ballast together in a dense and uniform manner, thus reducing specific compression stress. Therefore, subsequent settlements are only marginal and in this way, a more geometrically exact track structure is produced with considerably higher vertical and horizontal stability. The general practice of using reduced speed trains and quantifying axle loads tends to settle the track in an irregular fashion limiting the realization of long term benefits. The stabilizing unit is a well-proven design developed in 1975 with regular use on various railroads worldwide since 1978. Results of in-depth analyses by railroads throughout the world that use Plasser Dynamic Track Stabilizers are available for review. Advantages of track stabilization include savings because of longer maintenance intervals; and immediate reduction of slow orders after out of face track maintenance work. The PTS90C is also available with TampLink®, Plasser American's universal interface to connect different types of Plasser American machines/equipment with a tamping machine to increase work performance and provide more flexibility. The interface includes all necessary electrical/electronic, hydraulic, pneumatic and mechanical connections.
