Sub-themes

The workshop will be divided into three main topics covering three aspects of performance:


Operational performance

In the near future, railways will be expected to face a challenging growth of transport demand and to answer the objective of a significant modal shift from road to rail which is highly wished for in Europe for example, to overcome the problems of road congestion and environmental harm.
But modal shift to rail will come true only if we will be able to attract it.
To remain the mode of choice for investors and clients, railways needs not only to be cost efficient and environment-friendly, but also to guarantee a high level of quality of service and technical performance.
These performances have been gathered here as “operational performance”. They include the availability of the infrastructure, its reliability and resilience, its adaptability to changing conditions and, of course, the high level of safety that rail is always expected to offer.
Search for such improved performances have to be integrated at the early stage of design, and to be maintained throughout the infrastructure lifetime by adapted and efficient maintenance operations. Typical topics include:

• Design solutions for resilient infrastructure• Design for safety
• Upgrading track for future conditions• Advanced monitoring
• Toward an integrated system design• Infrastructure failure modes
• RAMS improvement through design• Monitoring the performance
• Low impact maintenance operations• Optimised maintenance for higher durability


Cost performance

For new tracks, the main challenge is to accommodate the conflicting demands of reducing the construction and maintenance costs, yet provide a railway that is low maintenance and future proof’? Yet, for existing tracks, the challenge is rather to balance maintenance costs and performance seeking adequate decision making at a global scale. Typical topics include:

• Design solutions for resilient infrastructure• Design for safety
• Upgrading track for future conditions• Advanced monitoring
• Toward an integrated system design


Environmental performance

To improve track performance in a global framework it is necessary to understand both the environmental effects generated when running trains, such as noise and vibration or flooding and landslide, and how the environmental challenges can influence the railway economic model in terms of maintenance or mobility. This section will explore modern methods to address these issues. Typical topics include:

• Ecological design : Noise and Vibration, Visual Intrusion (Cuttings, Land scoping)
• Environmental impact on biodiversity and circular economy
• Natural Hazards: Flooding, Landslides & Rock falling, Extreme climates, Earthquakes
