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
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/191384386> (that latter should've
been razed, not abandoned)

Then we think alike.

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.
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?
