Route(s) affected

Between Aylesbury Vale Parkway / Aylesbury and London Marylebone

Description

A fault with the signalling system at Great Missenden means that fewer trains are able to operate on all lines between Aylesbury Vale Parkway and London Marylebone via Great Missenden.

As a result, some services will be cancelled and a reduced service will be in operation. Trains that do run may be delayed by up to 15 minutes.

This is expected to be the case until the end of the day on Friday 13 November.

Customer advice:

Due to a fault with the signalling system at Great Missenden, services will be reduced to two trains per hour until Friday 13 November. This will largely affect the morning and evening peak, while daytime services may be subject to minor alterations. Where possible, services will be strengthened to accommodate passenger loadings.
