The Plasser Dynamic Track Stabilizer PTS90C is designed to apply specific and controlled stabilizing forces into the track structure at continuous speeds. Its purpose is to provide a controlled and accurate settling of the track after maintenance work. Dynamic track stabilization is a combination of horizontal vibration and vertical load applied to the track. Dynamic track stabilization consolidates the ballast together in a dense and uniform manner, reducing specific compression stress. As a result, subsequent settlements are only marginal and a more geometrically exact track structure is produced, with considerably higher vertical and horizontal stability, the company says.
