Ok, so the only abandoned stations that should be included are ones where the actual station still exists, even if it has been re- purposed. An abandoned station with the old platform visible and possibly a derelict building could be shown as railway=abandoned_station. A re-purposed station could possibly be tagged as building=restaurant and railway=abandoned_station? If all physical evidence of the station has gone then it should not be marked. Should the same rules apply to railway lines and to other historical features - ie if they have completely gone then they should not be marked? A railway line that is now a footpath, or a cycle path or even an identifiable strip of wildlife and tress should be shown but if it is now plowed fields then it should not be shown?
