Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate has been made of the average journey time between Swindon and London Paddington upon completion of the electrification of the Great Western Main Line.

Once electrification of Great Western from Paddington to Cardiff is complete, the average journey times between London Paddington, Bristol, Cardiff and Swansea are expected to reduce by around 15 minutes.

Precise journey times from London Paddington to Swindon will be confirmed as part of the industry’s timetable bidding process, later this year.
