I guess the main thing that is problematic about former railways is their
Between TIGER and GNIS and other imports, when I come across a road or
church that no longer exists (or in some cases never existed), I just
delete them. But before I delete the objects, I try to make some effort to
move them to their correct location where applicable. How am I supposed to
tell if these railways are in the right spot? In this specific case, I was
able to make an argument that the railway was in the wrong spot and you
managed to dig up a map that's more than 100 years old to help find the
correct former railroad location.
Where does the information about the geometry of these former railways come
from? What steps did you take to verify the data before putting it in the
OSM database? How are you going to document this information for future
mappers? It would seem to make sense to add additional information to a
source= or a note= tag indicating where the information about the previous
existence of the railway came from. Or maybe there can be more verbose
information added to the wiki somewhere.
