OpenStreetMap
In Brittany and particularly in the north coast we have a nice heritage of old railway bridge. I use to tag, these bridges as Railway = abandoned, bridge = yes and layer = 1. I was wondering whether we could redraw the complete railway net on OSM without interference with current highway.
What could be the best solution in the case a street was built on this abandoned railway?
Draw a way parallel to the street and tag it railway = abandoned?
Over the street but on a new layer?
Not to draw this abandoned railway at all in current OSM project?

If the rails are removed to accommodate the road then you should not tag the abandoned railway at all as it is no longer there. If however you have a case of a railway on a road (like a tram) then you can tag the way as both a highway and a railway at the same time.

I tag disused railways as railway=disused if the rails are still there. Otherwise I tag all historic railway routes, even if now a road, as railway=abandoned. If the roadway follows the railway exactly, no need for a separate way. I also tag the location of an old bridge if there remains any evidence of it with bridge=abandoned.

Many thanks both for your answers. I will definitely not, tag the complete railway net. But your hint RussNelson is a great idea: by tagging a way "even if now a road, as railway=abandoned". So I could leave my knowledge of these areas, in OSM avoiding any confusion.
