OSM's database can't hold all the information there is about everything. Among the many criteria for not including information are whether: - the data is ephemeral - it is better represented elsewhere - it distorts the OSM database Bus routes are on the edge of all of these. Where I live routes are changed frequently (sadly often by being removed). Route and timetable information would ideally presented together (some routes operate only once a week). There is likely to be a big increase in mash-up representations with OSM data as just one of the layers. Public transport information is ripe for innovative interactive presentation along these lines. I would prefer to wait the short time until this happens rather than distorting the OSM data unnecessarily.
