Tuesday 9th September 2025:

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

• RMT industrial action (London Underground).

• (Routine maintenance in the Oxford area).

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

• Until approximately 08.00: No Chiltern railways trains will call at South Ruislip. Some services will call additionally at West Ruislip instead.

• All day: Some additional trains will operate between Aylesbury Vale Parkway/Aylesbury and Marylebone (via High Wycombe).

In respect of the planned engineering works, the railway is closed in the Oxford area after 23.15, affecting the following late night services from Marylebone:

• 22.06 Marylebone - Oxford is diverted to Bicester North.
