Sustained performance of railway tracks

Objective

Experience with high-speed train in recent years has demonstrated unexpected settlement problems at certain sections of railway lines. This has caused railway companies expensive maintenance work and has become a concern in expanding high speed services which provide effective and environment-friendly transportation. The objectives of the project are: i) improving performance of railway ballasted tracks and reducing maintenance costs by understanding the dynamic and long-term behaviour of ballast using large-scale laboratory tests, ii) identifying weak portions of the railway network for retrofitting these locations by innovative, cost effective methods without interrupting train operation, iii) devising a global numerical model accounting for train-track interaction and non-linear behaviour of track components for a more reliable and cost effective design.
