Chiltern Railways warn of upcoming industrial action between 29 September and 6 October

Chiltern Railways has warned customers to expect disruption as ASLEF industrial action hits the network between 29 September and 6 October.  

On Saturday 30 September and Wednesday 4 October, no Chiltern Railways services will run on any route due to strike action by ASLEF. 

An overtime ban by the union is also in place on Friday 29 September and 2, 3, 5 and 6 October. This will mean a reduced service across most of the Chiltern Railways network, varying by route and station, and some early morning and late-night alternations to train times. Customers should ensure they check their full journey before travelling. 

On Friday 6 October, an RMT strike on the London Underground network will affect services along the Metropolitan Line, meaning that Chiltern Railways services will not be able to call at stations between Harrow on the Hill and Amersham.  

Customers are also reminded that engineering works will affect some journeys prior to the industrial action taking place, with buses replacing trains on some routes in the final week of September. Further information on engineering works can be found here. 

Chiltern Railways is urging customers to check before they travel at www.chilternrailways.co.uk, or the Chiltern Railways app.
