Railways are under pressure to become more efficient and cut their costs; innovation has a part to play in achieving these goals. The railway is, however, a complex and closely coupled system, making it difficult in the early stages of development, to be clear what the system-wide impact of innovation will be. The research covered in this paper stems from the idea that computer-based models of existing systems can help overcome this problem, by providing a framework against which the impact of innovation can be identified. The paper describes a repeatable modelling methodology developed for Great Britain’s (GB) railways,
which elicits objective system data from Railway Group Standards and integrates it using CORE®, a powerful system modelling tool, to create system models. The ability of such
models to help identify impacts is verified, using as an example the introduction of RailBAM (a new technology that acoustically monitors the health of rolling stock axle bearings) into the existing hot axle bearing detection system. Finally, the paper takes an initial look at the
structure of railway standards outside GB, to establish whether the methodology can be applied in other countries.
