Right - I was just trying to understand which was the canonical source. One of the things I've been wanting to try (but never have the time) is repair the OSM bus route relations based on the TNDS schedule info - which sounds very much like your track-finding system. But that gets dangerous if TNDS is indirectly pulling data from OSM itself..
