Overnight rail engineering works to affect journeys in and out of Cardiff, 19-21 July
- Region & Route:
- Wales & Western: Wales & Borders
Passengers travelling to and from Cardiff over the weekend of 19–21 July are advised to check their journey plans in advance due to essential overnight rail engineering work.
Network Rail is carrying out critical upgrades between Cardiff Central and Newport. This work is essential for the continued safety and reliability of the railway and will involve renewing rails, sleepers, and track stone, as well as work on the switches and crossings used to direct trains from one track to another.
The work will require overnight line closures from 1am on Sunday 20 July until 2:30am on Monday 21 July. This means there will be some amended train services:
Saturday 19 July:
- 20:30 Manchester Piccadilly to Cardiff Central will terminate at Hereford. A replacement bus will operate from Hereford to Cardiff Central.
- 23:18 Cardiff Central to Gloucester will not run. A replacement bus will run from Cardiff Central to Gloucester.
Sunday 20 July:
- 09:30 Newport to Milford Haven will start from Cardiff Central. A replacement bus will run from Newport to Cardiff Central, departing at 09:14.
- 09:53 Cardiff Central to Manchester Piccadilly will start from Hereford. A replacement bus will run from Cardiff Central to Hereford.
Services between South Wales and Bristol will also be affected on Sunday 20 July while important drainage and track work is taking place in the Bristol area:
- Until around 11:30, trains between Cardiff Central and Portsmouth Harbour or Exeter St Davids will start or terminate at Bristol Parkway instead of Cardiff Central. Replacement buses are planned between Bristol Parkway and Newport.
- Until around 16:00, trains between South Wales and London will use an alternative route between Swindon and Newport, stopping at Gloucester instead of Bristol Parkway.
Passengers, weekend travellers and concert-goers - notably those travelling to see Kendrick Lamar at the Principality Stadium on 19 July - are advised to plan ahead and allow extra time for journeys. Check the latest travel information at www.journeycheck.com/tfwrail
