I like to download portions of  the OSM database from Geofabrik and make 
custom maps for my GPS.  I also understand we're not supposed to map 
historic objects in OSM, and why some people don't want to see 
dismantled/razed railroads in the OSM database.  Being a railfan, I am 
one of those that do want them.    Assuming all the dismantled railroads 
in OSM were transferred to OHM, is there a way to take my OSM extracts 
from Geofabrik and add in the dismantled railroads from OHM, so that the 
resulting map would contain what I want?  I know I can use JOSM to copy 
data from OHM to OSM, but for a large geographic area I don't think that 
would not be practical.
