Dear all, when checking several maps in Germany, I found an area containing remnant after reconstruction (node [1] and adjacent ways; find attached also a sketch in a PDF file) where the tagging is not yet ideal (besides, e.g., railway:switch=default vs. 4 edges; upper right track is not rendered on openstreetmap.org due to tagging), but I do not have enough local and temporal knowledge. I subsequently assume that the Bing aerial image shows the current state with a probably removed diamond crossing with slips (einfache/doppelte Kreuzungsweiche) and some rails nearby. Probably, this is no problem for routing since tracks, which are tagged as abandoned or disused, might be ignored. Considering the use of the map for environment perception and localization (for research purposes; using OSM where one can quickly obtain a map from any space) the train can use neither the lower left nor the upper right track without derailment, since there is no physical connection any more. But, both ways are still connected to this centre node. Infering non-existence of switches from missing switch-tags is not a proper solution, since in most case there is a switch, but not yet a corresponding tag. For such special places I would prefer the lower tagging in my sketch splitting both unusable ways in a shorter abandoned part and a disused part taking also into account the past (using correct life cycle tags). How would you tag this scenario (assuming time and attention to detail)? What arguments are opposing my proposal? I am looking forward to receiving your helpful comments. Many thanks in advance!
