Saturday 31st May 2025:

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

• Planned engineering works (late night).
• (Routine maintenance at Oxford).
• Planned London Underground Metropolitan Line engineering works.

The railway is closed between Oxford Parkway and Oxford after 23.00, affecting all late night services to/from Oxford. During this period, rail replacement buses will operate between Oxford Parkway - Oxford and/or Bicester North - Oxford.

In respect of planned London Underground engineering works (south of Harrow on the Hill), an enhanced Chiltern Railways service of 2 trains per hour will operate between Marylebone - stations to Aylesbury/Aylesbury Vale Parkway for most of the day.

Finalised timetables are uploaded into online journey planners 9 weeks before the date of operation.

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.
