Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 9 June 2025 to Question 55867 on Rolling stock, what her timetable is for making an estimate of the potential impact of the time taken to introduce Class 701 rolling stock on the Waterloo-Reading line on costs to the public purse.

My officials are currently considering the most appropriate way to approach this issue. Given the complexity of this task, we are unable to commit to a timetable of when this work will be completed.
