Hi! Yes, I was afraid this might happen. I've never been the best on tagging and from what I read on the wiki, this seemed to be proper. I see the issue though. I only wanted to add them as they then show in Open Railway Map. I actually have pretty extensive knowledge of the subway, I've done research on it for both school and personal projects. Sorry if this is a dumb question, but do you know if there should be no historical data in osm? As the Cincinnati Subway is mapped here, but you say not in Open Historical Map, should all historical information go into Open Historical Map and would thing like Open Railway Map pull from Open Historical Map?
