The Shift2Rail/Horizon2020 project “Switch and Crossing Optimal Design and Evaluation” (S-CODE) is a partnership of nine organizations who have come together to consider radical solutions for the future of railway switching. The project used horizon scanning and backcasting techniques to identify potential game-changing technologies and concepts that may feature in future switch designs. Technical development and evaluation work streams have elaborated and prototyped these elements, allowing evaluation of their suitability both in isolation and as integrated sub-system solutions. The project is currently developing subsystem demonstrators and recommendations for technological elements to be included in future switching solutions. This paper presents a subset of the concepts and some of the technological developments being considered across the different technical work streams. The paper considers: condition monitoring and fault-tolerant control, wheel/rail interface optimization, locking and actuation mechanisms, Neoballast, and self-healing concrete and composite bearers, in the context of three novel S&C concepts.
