A strike and overtime ban by members of the ASLEF union on various days over the next two weeks will severely affect Chiltern Line services.

Chiltern has been working on contingency plans so that it can operate as many services as possible, but there will undoubtedly be a significantly reduced service and anyone intending to travel check beforehand to find out when trains are running.

On days when trains are running, there is likely to be a reduced service, and the last trains on all routes will be earlier than normal.

Monday, 29 January to Friday, 2 February, and Tuesday, 6 February

• London Marylebone to Oxford – normal service;
• Aylesbury to Princes Risborough – normal service;
• London Marylebone to Birmingham Moor Street – one train per hour;
• London Marylebone to Aylesbury Vale Parkway- one train per hour;
• Leamington Spa to Stratford upon Avon – a shuttle service will operate between 07:30 and 19:00.

Saturday, 3 February

• A greatly reduced service will be in operation because of engineering works.
• London Marylebone to Princes Risborough – the Chiltern main line will be closed.
• Rail replacement bus services will operate between Bicester and Aylesbury Vale Parkway, and Princes Risborough and Hillingdon Underground station, for onward connections into London.

Sunday, 4 and Monday, 5 February

• No Chiltern Railways services will operate.

Richard Allan, Managing Director at Chiltern Railways, said: “We understand the impact that this period of industrial action will have on our customers and we are sorry for the disruption to their travel plans.
“Customers should check their entire journey on each day of the period of industrial action, with operators affected differently on each day.”
