Description

Network Rail are electrifying one of Britain's oldest and busiest railways, providing greener, more reliable journeys and improving connections across southern England and South Wales: London and Bristol, including Cardiff, Newbury and Oxford. This project is also part of the London Railway Upgrade Plan, creating new connections and increasing capacity in peak hour by 30%.

As a result of this, all lines are closed between Hayes & Harlington and Maidenhead.

Please note that Great Western Railway are running a further reduced service between Swindon and London Paddington this weekend. More details can be found here.
