Train operator Chiltern Railways has warned customers to check before they travel this week due to strike action by the RMT.

On March 16 and 18, a significantly reduced timetable will be in operation, and trains will start later and finish earlier than usual.

On both dates, there will be no Chiltern Railways services between London Marylebone and Aylesbury via Amersham.

On this day, customers seeking to travel between London and Aylesbury can do so via High Wycombe.

There will be a later start to Chiltern Railways services on March 17 and 19, as well as some minor late-night alterations to a small number of services.

Chiltern Railways advise customers to check their journey before they travel on these dates and ensure they are aware of the last service of the day.

Customers can visit the Chiltern Railways strike page (www.chilternrailways.co.uk/strike) for more information.
