Railway track considerations

Railway track design will to a large extent determine the long term maintenance cost and track safety. Rail failures can result in loss of life and/or enormous losses in terms of recovery, repairs and loss of production. The design and maintenance of the track plays an important role in the safe running of a railway. This includes inspection of tracks, condition monitoring and maintenance process such as track tamping and non-destructive testing.
The selection of rails the best rail section for the application is very important. This can be achieved by ensuring that stress levels are understood and properly managed. In addition the selection of rail supplier based on process audits and quality assurance is important to ensure long term viability of the track system.

MCE provides railway track support and assistance with:

  • Track design evaluations - stress level in rails.
  • Factory audits and approval of rail suppliers.
  • Rail wear and stress relationship.
  • Effect of track condition on rail stresses.
  • Effects of rail stresses on rail welds.
  • Rail failure mode identification.
  • Rail welding specifications
  • Rail condition monitoring and failures.
  • and more....
