 I think I agree with Rainer: You propose to add a  "railway=" tag to a way that already has a "highway=" tag. So then why not just add "railway=tram" and delete the separate way? If this is not wanted (e.g. for rendering reasons) then I think we should use another tag instead of "railway=".

That's a good point, although I don't know whether the renderer is the main issue. There are lots of other tags that the renderer (rightly) ignores.
It might be construed as strange that a highway= has a rail= -tag and that the railway is, specifically, not rendered. But I'm not sure whether the semantics of my tag proposal are troublesome. What do other people think about this? The point of my tag-proposal after all is that there _is_, in fact, a pair of rails _on_ the highway.

Sorry, I'm not quite sure whether this a comment for or against the rail= -tag, but thank you for the input!

Since I initiated the voting process already, could you all please cast a vote on the poroposal page ( https://wiki.openstreetmap.org/wiki/Proposed_features/Tramtrack_on_highway ) and add comments so that in two weeks time I could possibly mend the proposal according to the vote and possibly have a new vote on the winning tag-identification. Yves, this would also make clear whether you are against or for the current proposal.

Thank you all very much, and please vote and add comments on the proposal page!
