Summary

Railway line drainage can improve stability, durability and load bearing capacity of the track bed and an absence of drainage often causes disorders. However, installing drainage devices on a conventional railway can be quite a challenge, both in terms of available ground space and working time.

To limit these constraints without degrading the durability of the track bed, an analysis to determine the importance of installing drainage devices is presented in this paper. The goal is to have a global vision of track response to frequent and extreme rainfall events.

Initially, the potential drainage capacity deficiency is determined by comparing the result of a hydrological study and the results of a hydraulic study of the drainage network for flows of different probabilities of occurrence in order to assess risks on the supporting structure. In addition, historical track maintenance data are analysed to identify areas where there is potential for poor track bed bearing capacity or a history of disorders on the earthworks which can be linked to a deficiency or absence of drainage.

This analysis enables an optimisation for upgrade works to be undertaken, decrease the cost of and reduce the constraints related to the works.
