NRE recently introduced an option to display valid routes for any particular ticket. If you hit the 'details' button for an itinerary it gave you the option to show all valid routes as a red line on a map (although it required a lot of zooming to make the station names appear).
Now that seems to have vanished, although the "other services you may use" button remains. However that just displays different departure times on the most obvious route. Seeing the valid routes in map form was very useful and sometimes revealed routes you might not have considered.
