Find out how planned engineering work could affect your journey. Network Rail normally updates timetables 12 weeks in advance.
However, because of the large number of engineering projects across the country, as well as the introduction of many new trains and services, they have been unable to do this recently.
Currently, Network Rail is unable to update timetables so far in advance. You should check your plans the week before you travel.
If you buy a ticket for a service that is significantly changed, or won’t run at all, you can travel on an alternative service, or apply for a refund. When there is upgrade work, train times and details for replacement buses shown in online journey planners may change. GWR advise you to book your tickets as normal.
Advance Single fares for many routes will still go on sale 12 weeks in advance, but where they don’t, they will be available as soon as the timetable is confirmed.
If Advance Single fares aren’t available, you can still buy Anytime, Off‐Peak and Super Off‐Peak tickets. If you buy one of these and later find a cheaper Advance Single fare on sale for the same journey, you can book this and ask for a refund on the original ticket – there will be no admin fee.
