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?
