Passengers are being warned Chiltern Railways will not operate on certain days this week due to further train strikes.
There are two further days of industrial action with the train operator not running on February 1 and 3 February on any route
This is due to strikes from The National Union of Rail, Maritime and Transport Workers (RMT) and Associated Society of Locomotive Engineers and Firemen (ASLEF).
The strike action is expected to similarly impact other neighbouring train operators, and as such, all Chiltern stations will be closed.
The decision to strike on February 1 coincides with a Trades Union Congress day of action where several unions are coordinating their strikes during the cost-of-living crisis.
RMT general secretary Mick Lynch said: "Our negotiations will continue with the rail operators to create a package on jobs, conditions and pay that can be offered to our members."
There will be a handful of minor amendments and cancellations to late-night services on February 2 due to the strike action.
Customers are also warned that due to Network Rail engineering works, London Marylebone station will be closed on February 4 and February 5.
An amended timetable will be in operation, with all Chiltern Railways services commencing and terminating at West Ruislip throughout the weekend, allowing for a connection to and from Central London on the London Underground.
Due to further engineering works, there will be no trains between Amersham and Aylesbury Vale Parkway, with a replacement bus in operation beginning at West Ruislip and serving stations between Amersham and Aylesbury Vale Parkway
