<div dir="ltr"><div><div><div><div>Apologies about being very late to respond to this issue.<br><br></div>I did use the historic:railway=* tag for old railway for a period of time having come across it somewhere in the DB. It was good because it was possible to tag which sort of railway it was<br>
<br>However... I now only use it in very particular circumstances because it was hard to pick railway features out of the DB. I now always use a current railway purpose using a railway tag, for example railway=rail, abandoned, proposed or construction etc.<br>
</div><br>If however there is also a secondary value for the tag, for example a former or proposed value then I would also use historic:railway=* or proposed:railway=*.<br><br>For example with a railway that is currently part of a light_rail system but was formerly part of a main line railway the tagging would be railway=light_rail, historic:railway=rail.<br>
<br>In one extreme case I found an old canal which then converted into a mainline railway and is now a cycleway which I think I tagged as tagged waterway=abandoned, historic:waterway=canal, railway=abandoned, historic:railway=rail, highway=cycleway. If there was a plan to bring the canal back into use (which there wasn't) I would have also addded proposed:waterway=canal!<br>
<br></div>This allows one to reliably use the railway tag itself to pick up all ways that have relevance to a railway map without having to check loads of prefixes and also allow the feature to contain a lot of temporal information.<br>
<br></div><div>I will put it on my very long list to do a cleanup of the orphan historic:railway tags which I added and which are not on ways with a railway tag unless someone does it first.<br><br></div><div>Does that make sense?<br>

</div>I don't oppose the change in principle, but we need to be clear what<br>
you intend for all the various values. railway:historic = rail,<br>
railway:historic = light_rail and railway:historic = tram can't all go<br>
into one railway=dismantled tag without losing information. I expect<br>
you intend to use another tag (dismantled = light_rail etc) but that's<br>
worth stating.<br>
<br>
Cheers,<br>
