Morebus route 3 (Poole - Wimborne) changes to a route 4 service (Wimborne - Poole) and vice versa using the same bus. This makes through journeys from Corfe Mullen to Merley possible on a single bus (and possibly even a single seat), albeit with the route number changing mid-journey. Are there many other examples of legitimate journeys of this kind that can be made using the same bus on two separate routes?
