The December 2019 GWR Timetable is now available.
Almost all GWR services are affected by this change. Some trains no longer stop at all the places you might expect them to. New ‘SuperFast’ services to London, for example, may not call at Chippenham and will not stop at Swindon or Reading – so you need to check before you board.
You can download the new timetables from the GWR website, or if you prefer you should now be able to pick up the new leaflets at major stations.
Either way, make sure you check the date on the leaflet. The timetable changes on 15th December; until then the old timetable operates.
