Chiltern Railways warns of engineering works taking place on Saturday 22nd and Sunday 23rd August

As a result, there will be no through trains between Marylebone and Gerrards Cross/Beaconsfield/High Wycombe, between Marylebone and Bicester Village/Oxford, nor between Marylebone and Birmingham.

Some journey times may take longer than usual, and passengers may have to change trains or travel with other operators to reach their destination.

Customers are advised that an amended and reduced timetable will operate on all Chiltern Railways routes.

Passengers travelling between Marylebone, Bicester Village, Oxford, Banbury and stations to Birmingham should travel via Aylesbury Vale Parkway and get a rail replacement bus service to Bicester North or Bicester Village to continue their journey.

Passengers travelling between Marylebone and High Wycombe only should travel via Amersham and board rail replacement buses. For Passengers needing to travel between London, Denham, Gerrards Cross and Beaconsfield, please travel via Hillingdon using London Underground Metropolitan Line services to/from Baker Street.

This work forms part of Britain’s Railway Upgrade Plan and includes Network Rail track improvement to increase the reliability of the rail network.
