A points failure between Harrow-on-the-Hill and Rickmansworth means that all lines are currently closed.
As a result, trains are currently unable to run between London Marylebone and Amersham, and will be cancelled.
We anticipate disruption will continue until 17:30.
Customer advice:
Services are operating between Amersham and Aylesbury / Aylesbury Vale Parkway only.
You may use your ticket on London Underground services via any reasonable route at no extra cost.
Check before you travel:
You can check your journey using the National Rail Enquiries real-time Journey Planner.
Compensation:
You may be entitled to compensation if you experience a delay in completing your journey today. Please keep your train ticket and make a note of your journey, as both will be required to support any claim.
