Please note: for a temporary period, Network Rail is unable to confirm train timetables as far in advance as usual. As a result, we expect online journey planners to be updated in the week leading up to periods of rail improvement work.

Swindon to Bristol Parkway
30 June and 1 July
Network Rail is planning upgrade work linked to electrification between Swindon and Bristol Parkway on Saturday 30 June and Sunday 1 July.
Trains between London Paddington, South Wales and Bristol Temple Meads will be diverted, adding to usual journey times. Coaches will replace train services through the Swindon area.
London Paddington to Cardiff Central or Swansea, services will be diverted between Reading and Bristol Parkway (adding up to 40 minutes to the usual journey time) and won’t call at Didcot Parkway or Swindon – on Sunday 1 July, services from London Paddington will terminate at Bristol Parkway, where connecting coaches will run to Newport for trains to Cardiff Central and Swansea
London Paddington to Bristol Temple Meads and Weston-super-Mare, will be diverted between Reading and Bath Spa (adding up to 20 minutes to the usual journey time) and won’t call at Didcot Parkway, Swindon or Chippenham

Bristol Parkway to Cardiff Central
16 June to 6 July
The Patchway and Severn tunnels will be closed for upgrade work linked to electrification from Saturday 16 June to Friday 6 July, inclusive.
As a result, long distance services between London Paddington and South Wales will run to an amended timetable and won't call at Bristol Parkway.
There will be a reduced service operating between London Paddington and Bristol Parkway with just one train an hour at peak times. You may need to change at Bristol Temple Meads for trains to Bristol Parkway.
Coaches will replace trains between Bristol Parkway and Newport as well as between Bristol Parkway, Patchway and Severn Tunnel Junction.
From Monday 2 July until Friday 6 July, replacement coaches will be extended from Newport to Cardiff Central due to reduced Arriva Trains Wales services operating as a result of upgrade work in the Cwmbran area.
