Use cases and conceptual system specification for Self-Propelled Wagon

Abstract

A state of the art review for the SPFW concept has been carried out as well as identifying and analysing essential use cases; Private yard load automation, Challenging Tractive Power and Braking Scenarios, Coordinating groups of self-propelled wagons and Autonomous loading/unloading. In order to understand the needs of operators, infrastructure managers, suppliers, and research centres, stakeholder needs analysis was carried out through conducting a physical workshop for Nordic railway stakeholders and an online survey at a European level. Moreover, this study presents, as a result of the state-of-art analysis, the needs analysis and identified use cases, a conceptual analysis on the impact of self-propelled objective on the digitalization of the freight trains, introduces a high level system architecture as well as a preliminary test.
