See http://www.openstreetmap.org/browse/node/533877725 for a not untypical NaPTAN bus stop
ref is on a plate on the stop (and is the numerical equivalent of the Naptan Code) local_ref is on a plate on the stop, and is used to tell adjacent stops apart My guess is that there are various coding systems, and they each need to have their own tag, otherwise they'll get confused. The data user needs to know the various tags if they want to use the codes. I'd reserve ref for a unique id that can be validated on the ground (if there is one).
