The work of the consortium of the European Commission funded project GaLoROI (Galileo Localisation for Railway Operation Innovation) is presented in this paper. GaLoROI aims for a certifiable satellite based localisation unit for railways serving as a base for modern train control systems allowing safe and precise continuous localisation of trains, which increases the capacity and operational performance in railways. Within GaLoROI the specifications of the localisation unit on the basis of railway’s current state of the art as basis for its technical and software development are derived. This is followed by system integration, validation, tests and demonstration runs. To enable the later certification of the localisation unit for different applications, the structure of the standard compliant safety case required in railways for every commissioning of new system or device is analysed and structured. The whole project is accompanied by an analysis of economical impacts to enable an introduction of the localisation unit into railway operations.
