August work to bring new trains to Wales and the West

Passengers who use the Great Western and South Wales mainlines, and those who live and work alongside these major railway lines, will benefit from a modernised railway thanks to work taking place this August.

Upgrading the railway means faster, longer, brand new trains with more seats can run, improving passenger journeys and increasing capacity.

This August will bring these benefits a step closer, as preparation for this upgrade work takes place from Swindon to Bristol Parkway on the Great Western mainline (Saturday 19 August to Friday 15 September) and between Cardiff and Newport on the South Wales mainline (Saturday 19 August to Sunday 3 September).

The work is the latest stage of the project to modernise the route between London Paddington and Cardiff. This upgrade will help support economic growth across cities and towns by improving the connection between South Wales and London. Electric trains now run between London Paddington and Maidenhead, with electric services due to start between Maidenhead and Didcot Parkway in January 2018.

More about modernising the Great Western route

In Wales, we’ve upgraded the Severn Tunnel and are raising bridges along the mainline to prepare for new, modern trains.

Swindon to Bristol Parkway

Piling will take place to install overhead line equipment (OLE) for electrification, alongside OLE installation through Chipping Sodbury and Alderton tunnels.

The Great Western mainline will be closed from Wootton Bassett Junction to Westerleigh Junction from Saturday 19 August to Friday 15 September, and from Westerleigh Junction to Filton/Patchway Junctions from Saturday 2 September to Friday 15 September.

This August there will also be flood resilience upgrades at Chipping Sodbury, and work to increase capacity at Bristol Parkway station will begin – this includes track renewals, upgrading signalling, building a platform and extending existing platforms. Bristol Parkway station will be closed from Saturday 2 September to Friday 15 September.
