In my environment, some people are adding old ("razed" railways to

It concerns both old railways which have been gone since 1933, e.g.
https://www.openstreetmap.org/way/592259029 (Note that this piece still
is somewhat visible, as it is now a road and partially a cycle path).
Hi Tijmen,
The "canonical" answer is that things that no longer exist in real
life and there is no trace of them do not belong in OpenStreetMap.
How strict you want to interpret this probably depends more on local
community consensus than on talk-transit guidance.
Tagging of removed railways that are now paths _in the same alignment_
seems relatively uncontroversial. https://osm.org/way/583243933 is an
example local to me.
Yeah, I hold that same thing too. Basically path and track I still
double-tag as railway=abandoned, but when it becomes a proper highway, I
generally don't.
I do tag razed when most of a longer railway is still (very) visible in
the field, but short sections are no longer, as e.g. they have become a
highway through/around a village. E.g.
<https://www.openstreetmap.org/way/419757167> or
<https://www.openstreetmap.org/way/191384386> (that latter should've
been razed, not abandoned)
Your example of way 592259029 seems to me a bit
ambitious in that it traces alignment where it is no longer evident,
such as over houses, and https://osm.org/way/592259043 is a bridge
that no longer exists... I would not include this in OSM.
Another example is a tram line in Amsterdam that has been gone for a
year now <https://www.openstreetmap.org/way/672838805>, the area has
been completely redeveloped, no trace of the old tram tracks remains.
IMO this should not be in OSM.
Then we think alike.
I only recently found out about openrailwaymap, but I can't find much
information about it. It seems it gets its data from the OSM database.
Is there a way to store "razed" railways somewhere else, so they will
show up on openrailwaymap but not on OSM (they are rendered on some
renderers, e.g. OSMAND)
There does exist
https://wiki.openstreetmap.org/wiki/Open_Historical_Map which is a
separate database intended for things that used to exist but don't
anymore.
Although this would be technically and legally possible, I doubt that
OpenRailwayMap currently integrates data from OHM.
Thank you so much!
To not "lose" the hard work of others, I have copied (part of) the
abandoned/razed railways from OSM to OHM, added it with data from
Wikipedia. Now I have to remove the data from OSM, but that's quite some
work so I will do that later.
<http://www.openhistoricalmap.org/?edit_help=1#map=16/52.7820/4.8315&layers=H>
Thanks for that!
Btw, do you know of a way to copy data from one layer in JOSM to
another, while keeping it at the exact same position?
