Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 7 September 2026 to Question 26119 on East West Rail Line, how many trains require modification before passenger services can commence between Oxford and Milton Keynes; how many have been modified; and when she expects modification and testing of the full fleet to be completed.

All trains for the Oxford to Milton Keynes service require a set of modifications before they can enter passenger operation. Modifications are nearing completion, and a full testing regime is underway which will support the safety validation process. We will provide further updates on modifications when they are complete.
