Question to the Department for Transport:

To ask the Secretary of State for Transport, whether there are plans for an investigation to be undertaken into the multiple signal failure in the Surbiton area on Friday 11 June 2021.

Following the disruption to train services at Surbiton on 11 June, Network Rail has undertaken a review to understand the cause of the signal failure and limit the impacts of a similar future event. South Western Railway are reviewing their communications plan to ensure that passengers are kept well informed in the event of any future disruption. The Department has asked to be kept fully informed about the implementation of these reviews.
