Special Session: RW2016-S19
Rehabilitation of Old Railway Lines:
Technical and Economic Issues
Session Aims and Scope

Many railway lines in different countries have been in operation for more than a hundred years. Due to the future demands concerning faster and heavier trains, railway structures can experience problems, such as instability, relevant permanent deformation, and possibility of extensive vibrations. These issues have an adverse effect on the safety, reliability and economy of the railway operations.

Engineers are faced with the task to assess the performance of these railway tracks and if necessary to design appropriate strengthening measures. The adaptation to modern trains or increase of traffic requires a detailed characterization of the existing infrastructure, by identifying the nature of the materials and their state and by evaluating their strength and stiffness.

In the case of very old railway tracks, the substructure is usually very heterogeneous, making the collection of representative samples difficult and rendering the representativeness of the characteristics determined in laboratory debatable. Those facts, together with the amount of information necessary for the generalised renewal of a track platform along significant sections, may be decisive for making it more favourable, from a technical and economic point of view, to focus on the “in situ” characterisation methods, rather than on the laboratory characterisation even with sophisticated techniques.

These challenges are finally an opportunity to propose other approach like integrated environmental, conception and economic.

The Session should bring together Railway, Civil and Geotechnical experts and will cover, but not limited to, the following topics:

  • Characterization of old railway tracks (Load tests; GPR; Penetrometers)
  • Evolution of track properties: geometric quality, track stiffness
  • Monitoring and modelling of problematic zones
  • Soil reinforcement techniques and treated soils
  • Mitigation of railway induced vibrations
  • Innovative solutions
  • New construction techniques
  • Drainage problems
  • Recycling old materials
  • Techniques for cleaning the ballast
  • Remediation of polluted sites
  • Effects of climate change on railway infrastructure
  • Modelling of rail track degradation
  • Risk analysis
  • Maintenance and renewal alternatives
  • Optimisation of track possession time
