5th August 2023

Saturday 5th August 2023:

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

• Planned engineering works.
• ASLEF industrial action (overtime & rest day work ban).

The railway is closed between Oxford Parkway and Oxford all day. Rail replacement buses will operate as follows:

• Oxford Parkway - Oxford.

In respect of industrial action, a generally reduced service will be in operation and in particular a limited service between Amersham and stations to Aylesbury only will operate on the Marylebone - Aylesbury Vale Parkway route.

• No trains will serve Aylesbury Vale Parkway.
• London Underground services should be used between Baker Street and stations to Amersham.

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.
