Hi Nathan:
Good to see your thoughtful questions here on talk-us. I have seen
your edits and I believe you have a depth of knowledge about tagging
railroads already.
I believe in tagging attributes that we know to be true about things
as we edit them, or before we edit them. Tagging is free-form, but
free-form can include being thoughtful, especially as it incorporates
deep personal knowledge. Smarter tagging includes reaching out to
others who might or do have deep knowledge. In other words, while
one smart person making a proposal is good, two or more putting their
heads together (especially with complementary or
multiplicative/non-overlapping experience) is even better. And
builds consensus and community.
No doubt you have seen that historic=ruins is a tag used to attribute
a specific semantic: something either like a castle, fort or wall or
might have been a castle, fort or wall, or goes in that direction.
"Historic" in this sense goes back hundreds of years, or certainly
thousands. Railroads, especially the earliest ones, might make it to
a sesquicentennial and so encroach this boundary, but early railroads
are an interesting blend of technological industrial achievement in
the context of human historic ruins. Food for thought. I think
historic=railroad and ruins=railroad can both work, in the right
contexts. Help to sharpen these up!
I don't know how the ruins=railroad tag might already be established;
tagwatch isn't my forte, anybody?
Rail-banking is a real legal and "along a spectrum" activity that OSM
should accommodate. Perhaps a full description of this spectrum in
an OSM wiki page with various proposal tags might emerge with you?
If you have a reasonable perspective on how tagging might begin,
evolve, grow and be (become) useful, I think OSM as a project invites
you to bring it forward as best you might advance the subject.
So, soliciting how railways are used, banked, contribute to
"accidents" (as "John F. Eldredge" <j...@jfeldredge.com> writes) is
knowledge that you might have (maybe you do), others might have, and
others certainly do not. The right thing to do is to have OSM best
capture both what you know (in the real world) and "about" railways.
You might write up a wiki page that proposes certain tags in certain
circumstances, this is one way OSM grows. Do your best to posit a
smart set of tags, an intelligent way to use them using the concept
of a life cycle of railroads, and "best express" this as a tagging
scheme.
Then both use it, document, and improve it. I'm not just talking to
you (Nathan) here, and I'm not just talking about railroads. I'm
talking to everybody in OSM about everything: using things (tags)
smartly and documenting and gaining consensus and making it smarter
as we go (while getting intelligent feedback in a loop while growing
better and smarter ad infinitum)... simply IS our OSM and how it
works. On a good day.

Hello got some questions about Railroads,
I have a passion for the preservation of railroads and the maps
surrounding them. I both update current map data with a line per
each track. Track is in most cases two rails attached by a sleeper
or tie. I have over 10,000 edits over on GMM and under 4,000 with
OSM.
I am mostly coming to ask about historic railroads and how to map them.
In my area we have lots of rail trails, these trails mostly have
been mapped by
bicycle=yes
foot=yes
highway=cycleway
horse=yes
name=John Wayne Pioneer Trail
note=railway=abandoned indicates a rail-trail
old_railway_operator=Milwaukee
railway=abandoned
Ect......
Is this the way that we should be mapping these as there are
historic attributes.
For instance we could add.
historic=ruins
ruins=railroad
or we could remove railway=abandoned
but in this case the railroad is rail banked and could be brought
out of abandoned status.
We have other routes in the state that are not rail banked and are
historic and are not seen as abandoned.
Best Regards,

We probably need a value such as railway=inactive for routes that
are not in use, but still have the rails in place. The only problem
is that, if someone erroneously tags an active but little-used route
as inactive, this could lead to an accident if someone went hiking
or rail-biking on the route.
