On track for success
A promising technology developed in Germany could be set to revolutionize future railway track construction.
A promising technology could be set to revolutionize future track construction. The Frenzel-Bau group, a company specializing in railway construction, has developed the innovative track system Durflex in conjunction with Bayer MaterialScience and its wholly owned subsidiary Hennecke.
It is characterised by its outstanding noise damping properties and longevity. With this innovative system, gaps between the ballast stones are completely filled with a polyurethane foam. The displacement of ballast stone that typically occurs as a result of the dynamic forces associated with rail traffic is prevented, as is the wear normally associated with this displacement.
In the Lower Saxony town of Uelzen, a 300-metre-long pilot section of the new system is being trialed and is due to be opened up to regular rail traffic this month.
Construction of the test section has been subsidized by the German Federal Railway Department, the Federal Ministries for Transport, Construction and Urban Development, and the Federal Ministry of Economics and Technology.
