Heavy freight trains are those with an axle load of 25 metric tons and above or a total train weight of at least 5,000 metric tons – this means that enormous loads take effect on the superstructure components. With heavy traffic routes, the main priority is to guarantee the availability of the route. Long closure periods cost the operators a significant amount of money.
Getzner has developed solutions specially for this sector to increase the availability of heavy traffic routes. In addition, the installation of elastic components extends the service life of the superstructure and lowers the life cycle costs.
Getzner products and services are used successfully in the heavy freight sector throughout the world.
Heavy traffic route with axle load over 33 metric tons
Increased wear on superstructure components
Repeated periods of closure due to high maintenance requirements
„Modifying the stiffness enables the maintenance costs for a section of track to be considerably reduced. Getzner offers various solutions to this end. On the MRS track, the Getzner materials provide the superstructure with the required level of elasticity. In addition, it is clear that the rail pads do an exceptional job of withstanding the extremely high loads.“Antonio Merheb, Technical Manager at MRS Logistica S.A.
Axle load of 30 t
High frequency, high tonnage
Above-average amounts of wear on high-grade rail steels and sleepers
„Trafikverket knew that under sleeper pads help significantly to protect the ballast. But no-one had ever tested whether this solution would work as efficiently and on this scale north of the arctic circle before. The ideal load distribution within the track was required. This was the goal behind the attempt to reduce the stress between ballast and sleeper by enlarging the area of contact between the sleeper and the ballast. Under sleeper pads, such as those offered by Getzner, are perfect for such a scenario.“
High frequency of trains (100 to 130 trains per day with daily gross tonnage up to 1.3 MGT)
Destruction of ballast due to exceptionally high loads
Short tamping intervals
„By conducting comprehensive analyses of the track geometry and maintenance records, we could verify a significant reduction of maintenance costs and numerous positive effects on the track were witnessed since the introduction of Getzner USPs.“Quanxian Wang, Senior Engineer of the Taiyuan Railway Bureau
