Chiltern Metropolitan Line services to be impacted by London Underground industrial action next week

Chiltern Railways is warning customers travelling on its Metropolitan Line services between Aylesbury and London via Amersham that their journey will likely be affected due to industrial action by London Underground staff next week (7 - 12 January 2024). 

The impact of the strike action by London Underground staff on Chiltern Railways will differ each day due to the nature of the action, where different teams are taking action on different days. 

Chiltern's Metropolitan Line trains to Aylesbury via Amersham operate on London Underground infrastructure which is controlled and signalled by London Underground staff. For this reason, timetables will be heavily amended next week.
