To ask the Secretary of State for Transport, what steps she is taking to improve the reliability of Govia Thameslink Railway train services between Sutton Common and Wimbledon.

Govia Thameslink Railway and Network Rail are working closely to improve reliability of services between Sutton Common and Wimbledon, including through better management of trespass incidents, improving signalling infrastructure reliability and increasing the train driver establishment to improve availability and avoid cancellations.
