Question to the Department for Transport:

To ask the Secretary of State for Transport, how many and what proportion of rail journeys between Kemble and London Paddington are made using Advance tickets rather than regulated fare products.

The Department does not centrally hold information on how many, or what proportion of, rail journeys between Kemble and London Paddington were made on Advance tickets rather than regulated products. While detailed fares data exist within industry systems, the Department does not routinely compile journey‑by‑journey comparisons and producing this information would require bespoke analysis.
