Railway networks are complex systems and the management of such systems is a challenging task for railway asset managers. It is their responsibility to ensure that the network delivers the highest level of performance for all stakeholders, whilst adhering to strict safety regulations and financial constraints. Historically, Reliability, Availability, Maintainability and Safety (RAMS) analysis has been used to assess the performance and safety of railway networks, nonetheless there is a lack of consistency in approaches across the industry, with analysis often influenced by the key stakeholders at the time. This research demonstrates an application of an Extended RAMS framework on the UK Railway Network, the Extended RAMS frameworks aims to consolidate various extensions to the traditional RAMS approach in to a single universal approach, which is beneficial to all stakeholders. This paper explores the data currently available within the rail industry and how it can be used to assess the ten metrics within the framework. The final part of the paper explores how the parameters within the ExRAMS framework can be used as the bases of a value analysis, which can be used to assist with asset management decisions
