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.
