Project Information:

The Great Western Route Modernisation project is the biggest investment in the Great Western railway since Brunel built it more than 150 years ago. Modernising the route will improve the experience of everyone who uses it and stimulate economic growth in the South West and beyond.

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%.
