Many "way" elements in OSM are tagged "railway." OpenRailwayMap builds upon them, adding numerous details. However, the lack of "relation", between "ways" no longer used as railways, hinders the analysis of abandoned lines. Knowledge from the realm of Volunteer Geographic Information can bring the missing link, while leveraging the accuracy of OSM data. This article aims to add nodes of thousands forgotten stations, and to fill hundreds gaps between scattered OSM elements, which are unaware of their former railway line affiliation. The experiment covers almost entire old railway networks of France and Belgium.
