Thanks. We felt for London commuters just the live image of the map would be enough to enable them to visualise their route. And for tourists/infrequent users the added route planning would show them how and why they should take a particular journey. You can also manually open and close stations/lines and get instant feedback on how that effects the planned journey (although this is mainly hidden in the UI)
