More than 40 years, more than 900 machines 

42 years ago, the first dynamic track stabiliser was presented at the Permanent Way Conference in 1975. At the successor event, iaf, a DGS will also be put on show in Münster in 2017. In the meantime, more than 900 track stabilisers have been supplied to 45 countries. On all continents, the machines have become indispensable to safe railway operation – particularly on high-speed lines. Combining vertical load and horizontal oscillation, only the DGS ensures the required physical properties of the ballast bed. They result from the controlled initial settlement produced after track laying or maintenance. 

Variable impact force 

With the introduction of the radially displaceable imbalance referred to as “variable impact force” a further improvement meeting the demands from practical operation has been achieved. In sensitive environments, with lineside residents or on bridge constructions, work can be performed with minimum vibration at adapted speed. Barely visible, the technical further development makes the track geometry even safer and extends the service life of ballasted tracks even more. The controlled anticipation of the initial settlement ensures a durable track geometry. Put on show at iaf, the independent, self-propelled DGS 62 N in open design is operated by MAV on standard gauge lines across Hungary.
