Smart because it's efficient

Rail and turnout maintenance

The need for sustainable rail maintenance is growing

The reasons are obvious: higher track loads resulting from generally higher traffic volumes are often accompanied by higher speeds and/or axle loads. These either lead to increased rail head wear with surface deformation in the longitudinal and/or transverse direction, or the extreme pressure and shear forces result in fatigue and crack formation. Since the resulting rail damage not only impairs ride comfort due to vibration and noise, but above all jeopardizes operational safety, it must be removed by grinding or milling.

 

When timetables are tightened and extended over longer hours, the time windows available for inspection and maintenance activities become shorter. This means that they must be designed to be minimally invasive to operations, which further increases the complexity of maintenance. A first step toward increasing network capacity is to significantly increase the proportion of preventive measures in relation to corrective measures.

Our answer: An intelligent strategy for every track type

That is why our portfolio covers all areas: from condition assessment and rail inspection to analysis of maintenance requirements and appropriate grinding or milling techniques for rail processing. Thanks to our extensive fleet of processing machines, each distinguished by complementary capabilities, we are able to cover all required rail and turnout maintenance tasks across every type of rail network.

We define the ideal solution for your needs together with you, taking into account the following parameters, among others:

  • Material removal per pass
  • Cost per finished meter (including operational complication costs and deployment expenses)
  • Operational flexibility (including deployment availability, planning effort, and delivery/logistics)
  • processing speed
  • reprofiling capability 

Smart Maintenance increases network capacity

High Speed Grinding (HSG) is an essential component of preventive rail maintenance. With operating speeds of up to 80 km/h, HSG is the world’s only technology capable of processing rails during ongoing traffic. In its smart configuration, the integrated measurement technology of the HSG grinding train continuously records the transverse and longitudinal rail profile and detects potential cracks at the running edge (head checks) using eddy current testing. The sensor-acquired data is preprocessed and transmitted to the cloud, where the current condition of the rail is intuitively visualized in mapl-e using traffic light colors. The complete overview makes it possible to prioritize the route sections which are to be worked on and to plan appropriate measures in a targeted manner. mapl-e thus simplifies the entire planning and control process for rail maintenance.
