I don’t have anything to do with OpenRailwayMap, but I do look after a map style that shows razed and dismantled (as well as abandoned, extant and proposed) railways.
A worked example of what I’d need to do to use OHM and OSM data would be most welcome** (including any legal aspects - if I combine the two in one display layer are there any issues?
Also, from the perspective of people who have added razed and dismantled railways to OSM, what do they need to do to move them to OHM - both the technical aspects and the legal aspects?
** a pull request at https://github.com/SomeoneElseOSM/SomeoneElse-style would of course be welcome for the technical part of this.
