When you click a "Timetable "link from the detailed itinerary section of a journey plan, you will present the timetable for that service. You will notice that the entire timetable for the selected service is presented. This is useful since you can view information relating to earlier or later trips.
To view the timetable for a particular trip, click on the service number for that trip. This will present details of the selected trip including the date, service number, route name, service provider and the stops served by the selected service. If the stops form part of your journey they will be shaded differently.
