Great Western Railway

Engineering work is taking place to electrify the lines between Newbury and Reading, in connection with the Great Western Route Modernisation major project.

Work will be taking place on various weekdays and most weekends up until the end of 2018.

How will this affect my journey?

Trains between Newbury and Reading will not run. An amended train service will run between Theale and Reading to help maintain connections.

Buses will be provided between the following stations:

  • Newbury / Thatcham and Reading (peak times only)
  • Newbury and Didcot Parkway (peak times only, change for connecting trains)
  • Newbury and Theale
  • Newbury and Bedwyn
  • Bedwyn and Reading (peak times only)
  • Bedwyn and Theale
  • Pewsey and Swindon (for connecting trains)
  • Pewsey and Westbury

To keep daytime work to a minimum, Network Rail will sometimes work during the night, especially at weekends. If you travel after 21:00 on weekends, and before 11:00 on Sundays, we strongly recommend checking your journey before you travel.

As long-distance High Speed Trains will be diverted via Swindon and Melksham, local stopping services between Swindon, Chippenham, Melksham, and Trowbridge will be changed whenever the work at Newbury is taking place.

On Weekdays where the line is closed at Newbury, buses will be provided to run between Chippenham and Westbury in place of some trains. On Weekends, trains will continue to run but may depart at different times.

Ticket acceptance:

To help you with your journey, tickets will be accepted on alternative bus routes in both directions; these include:

  • JetBlack 1 between Newbury, Thatcham and Reading
  • Kennections 102 between Newbury and Thatcham
  • Thamesdown R20 / X22 between Marlborough and Hungerford
  • Salisbury Reds Activ8 between Amesbury / Tidworth and Andover / Salisbury
  • Salisbury Reds X5 between Salisbury, Pewsey and Swindon
  • Salisbury Reds 2 between Devises and Salisbury
  • Stagecoach 80 between Ludgershall, Tidworth and Swindon
  • Stagecoach 55 between Calne and Swindon
  • Stagecoach 49 between Trowbridge, Devises and Swindon

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%.
