Abstract

Excess water in railway track substructure can significantly decrease service life and increase maintenance cost. If the rail track experiences a flash flood, derailment can occur or significant damage can result. In some cases, if the train runs with water inside the track, it can cause substantial damage to the railway track. Moreover, at recovery periods after flood, the track is more susceptible to dam-age; needing proper support and maintenance. This paper focuses on subgrade behaviour before and after flooding including subgrade softening and collapse behaviour. Full-scale tests were carried out in the experimental facility GRAFT-I (Geopavement & Railway Accelerated Fatigue Testing) at Heriot-Watt University to investigate the impact of flooding on track response. The results showed that the presence of water dramatically decreased track performance.
