Holding up to 400 million metric tons
With trains roughly two km long - and with axle loads of up to 33 metric tons - the heavy traffic route is an arterial link between Brazil's eastern coast and the country's interior. A total load of 400 million metric tons traversed the railway line during the three-year test, which roughly equates to the ten-year figure for a heavily used route in the German rail network. The considerable wear endured by the superstructure components resulted in high maintenance costs and reduced the availability of the 1674 km line.
Quicker, more effective impact on the superstructure
"It is clear that the rail pads do an exceptional job of withstanding the extremely high loads. By altering the stiffness of the track, the maintenance costs for a railway line can be slashed," emphasises Antonio Merheb, head of engineering at the rail operator MRS Logistica S.A. As a further benefit, the rail pads can be installed or retrofitted quickly and easily.
Results of the case study
- Successful long-term test of a heavy traffic route
- Measures to reduce wear
- Efficient solution to reduce maintenance costs
