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?
