I need to reopen this thread. We have not arrived at a consensus so far in this talk, Nevertheless the wiki page Demolished_Railway <https://wiki.openstreetmap.org/wiki/Demolished_Railway> was completely rewritten on 07:17, 27 May 2020 by Mateusz Konieczny <https://wiki.openstreetmap.org/wiki/User:Mateusz_Konieczny> In particular the wording " Here railway is gone without any trace in terrain except possibly road alignment. Its course is well documented, but such historic feature is out of scope of OpenStreetMap, should not be mapped and should be deleted if mapped" in the caption of the first picture is certainly something we were talking about, but had not agreed upon. This rewrite in the middle of an inclusive discussion on the main aspect of the page seems to me not correct. As far as I remember (I may not have read all the contributions in all details) we did not talk about rewriting that page. I do object strongly to the invitation to remove the razed/dismantled-railway tag in the case of railway tracks have been replaced by roads with the same geometry. To the contrary this is one of the more fortunate cases where the original route has been conserved, and it is easy to travel along a historical railroad. I admit that I have a faible for industrial archeology (like former railways, watermills, old canals) but they do have touristic value and for that reason should be in OSM.
