An amended timetable will be in operation, in respect of the following:
- Planned engineering works - 1st to 8th February 2026.
- (Major station/track works at Oxford).
Whilst Chiltern Railways services will continue to operate between Marylebone and Oxford, some minor timetable alterations are necessary in order to operate lengthened trains. Chiltern Railways services will be busier than usual, due to no direct Great Western Railway services between Paddington and Oxford.
- Customers traveling to / from Saunderton should note that from Monday 02 through to Friday 06 February, a revised northbound timetable will be in place. To travel to / from Saunderton on a train heading away from High Wycombe or London Marylebone, for most of the day you will need to catch a different train to normal.
Please check your journey times carefully before travelling.
