That sounds fine, modulo "abandoned" vs "old_railroad_grade". I usually look to USGS for guidance and prior art - their 1:25000 topo maps are an inspiration. They distinguish among 'railroad', 'abandoned railroad', and 'old railroad grade'. According to their classification, abandoned railroads have visible tracks. In the US 'abandoned' is a legal/technical term, an no tracks more or less 100% implies abandoned. A case I found that's semi relevant, in that it's about abandonment and rail trail conversion: http://www.ll.georgetown.edu/federal/judicial/dc/opinions/94opinions/94-1403a.html The current tag definition is awkward: http://wiki.openstreetmap.org/wiki/Key:railway because tags mean something unintuitive: abandoned => "old railroad grade" disused => abandoned (this is missing a key differentiating point) disused => "out of service" (this is fine, just the usual uk/us translation) rail => "in server" (this is fine)
