Abstract

Adequate drainage is a critical factor for the proper functioning of railway infrastructures and an important element of track maintenance. Railway drainage systems are complex and consists of various components, which can directly or indirectly affect the performance of other assets such as earthwork, track and signalling equipment. This has made the management of railway drainage systems challenging. Furthermore, with budget constraints, selecting appropriate maintenance strategies are essential. This study attempted to develop a risk-based decision making framework, for the strategic management of assets. The developed framework is capable of handling the uncertainty associated with inconsistent historic data and the probabilistic nature of asset deterioration. Moreover, it can identify significant contributing factors that affect the deterioration rate of asset and predict the future condition of them. The framework enables decision-makers to proactively manage their network and to determine the optimum maintenance strategy, by considering factors such as budget, maintenance intervals, maximum allowable risk, and the overall condition of the network. The developed framework is demonstrated via a case study on a section of the UK’s railway.
