To prepare for the new Intercity Express Trains, Network Rail need to test the overhead wires in the Reading area which will affect some nearby services.
Replacement buses will run on all routes through Reading, and some long-distance trains will be diverted resulting in longer journey times.
Trains will run on the following routes:
- Bristol Temple Meads to Didcot Parkway/Oxford
- Newbury to Exeter and mainline stations in Devon and Cornwall
- Theale to Newbury/Bedwyn
- Didcot Parkway to Oxford and stations to Worcester
- London Paddington to Maidenhead
Replacement buses will run on the following routes:
- Reading to Maidenhead
- Reading to Reading West, Theale, Newbury
- Reading to Tilehurst, Pangbourne, Goring & Streatley, Cholsey, Didcot Parkway
- Reading to Reading West, Mortimer, Bramley, Basingstoke
- Slough to Newbury
- Maidenhead to Twyford
- Twyford to Wargrave, Shiplake, Henley-on-Thames
- There is also work taking place between Bristol Parkway and Cardiff on these dates.
If you’re planning to travel between London and South Wales, please check your journey carefully.
From Monday 12 September to Friday 21 October 2016, the Severn Tunnel will be closed to enable electrification through to Cardiff and Swansea.
The three main stations affected are Bristol Parkway, Severn Tunnel Junction and Newport.
Newport to London services will be diverted and replacement buses will run between Newport and Bristol Parkway.
Alternative timetables will operate, with journeys from Newport to London taking about 35 minutes longer and Newport to Bristol 45 minutes longer.
Throughout the period the rail replacement coaches will be running between Bristol Parkway and Newport as well as Bristol Parkway and Severn Tunnel Junction, with multiple coaches and standby vehicles on all peak services.
Arrival in Parkway and Newport is set to meet the majority of connections where a full train service will run.
There will be extra customer service staff at all locations with information on connections.

From Saturday 27 to Monday 29 August, the railway between Bristol Temple Meads, Bristol Parkway, Gloucester and Severn Tunnel Junction will be closed with many services being amended or replaced by buses. For more information visit the GWR website.
On Sunday 2 and Monday 3 May rail replacement buses will be operating between Swindon, Chippenham, and Bath Spa, and between Swindon and Bristol Parkway. You can use the GWR journey checker to see if your route is affected.
