The ON-TIME real-time railway traffic management framework: A proof-of-concept using a scalable standardised data communication architecture

•A scalable standard framework for managing railway operations is presented.•A web-based architecture communicates standard railML data among modules.•A proof-of-concept is provided by an application to the Swedish Iron Ore line.•The framework works independently from the algorithm for optimal replanning used.•The bases are set for achieving real-life interoperable traffic management.
