Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to Answer of 14 September 2022 to Question 45030 on Railways: Greater London, what steps her Department is taking to monitor the potential impact of reductions in rail (a) services and (b) capacity on the use of private vehicles in London.

We are not monitoring the impact of changes in rail services on car usage, however, we are focussed on ensuring Govia Thameslink Railway are making evidence-based timetable interventions to better optimise service levels to balance capacity and demand.
