An alternative would be to specify a part of a way by starting and end  
node (a "subway", compare http://wiki.openstreetmap.org/index.php/Relations/Proposed/Segmented_Tag) 
. If the routes are to be stored in OSM as relations, this wouldn't be  
a such good idea, but assuming you're storing them externally and  
didn't want to write to the OSM database, it's an option.
