7th September 2025

Sunday 7th September 2025:

An amended timetable will be in operation, in respect of the following:

• RMT industrial action (London Underground).

Industrial action by London Underground RMT members will affect our ability to operate certain aspects of our service. The following timetable alterations apply:

• All day: No Chiltern Railways trains will operate between Marylebone - stations to Great Missenden. A limited shuttle service will operate between Aylesbury - Stoke Mandeville - Wendover - Great Missenden. No trains will serve Aylesbury Vale Parkway.

 Finalised timetables are uploaded into online journey planners 9 weeks before the date of operation. Please check your journey in the planner at the following link: https://buy.chilternrailways.co.uk/. Any journey checked outside of this timescale may be subject to change; please double-check how these amendments are due to affect your travel plans. For some engineering works and special events at Wembley Stadium, timetables may be released closer to the date of operation.
