We're modernising the Great Western route to bring passengers faster, more frequent, more reliable services.
The project includes upgrading our infrastructure so that the route can be electrified.
This page explains the work we'll be doing in South Gloucestershire and when it's due to take place.
The following time-lapse film shows electrification upgrade work completed in the Old Patchway tunnel and Pilning area near Bristol.
Steelwork / Masts
From Saturday 15 September until Sunday 7 October we will be working around the clock while the railway line through Bristol Parkway is closed. We will be installing any remaining foundations (piling) for the electrification equipment as well as installing the masts and gantries required to support the overhead wires.
Swindon to Bristol Parkway station
This year, we will be finishing electrification of the railway line from London to Bristol Parkway.
Between Winterbourne and Stoke Gifford Junction, and along the Filton East Curve, we will be working during the following periods:
Between August 2018 and the end of October 2018 we will continue to work overnight on Saturdays to install the electrification equipment. We will also be working on Sundays (during the day).
From Saturday 15 September until Sunday 7 October we will be working around the clock while the railway line through Bristol Parkway is closed. We will be installing any remaining foumdations (piling) for the electrification equipment and putting up masts, gantries and overhead wires.
Over the same three-week period we will be working between Royal Wootton Bassett Junction and Winterbourne viaduct to test the equipment we have already installed.
We’ll also be working over the weekend of 13-14 October through all the above areas as testing continues.
There may be times where we are given last-minute access to the railway to carry out work. In this instance, the work may take place with no notice. Please keep an eye on this page for updates

Filton Bank Four-tracking
This project is working in Bristol and South Gloucestershire to improve capacity and allow for an increase in trains form 2019. It involves installing two new railway lines between Bristol Temple Meads and Filton Abbey Wood and will mean more and faster journeys between Bristol and London Paddington. Find out more on our Bristol Upgrades page.
Filton Abbey Wood station
We are working at the station as part of our Filton Bank Four-tracking project to double the number of tracks between Bristol Temple Meads and Bristol Parkway from two to four.
A fourth platform will be built at Filton Abbey Wood station with ramped access to the existing footbridge. In order to support the embankment, we are building a retaining wall between the site of the new platform and the residential area that backs onto the railway. This phase of work is under way. Later in 2018 we will extend the three existing platforms and lay the new track.
The footpath that links the car park in Emma-Chris Way to the station footbridge is now open. The diversion route along Nutfield Grove and through the grounds of Nutfield House has closed.
Patchway Tunnels upgrade
From 16 June until 6 July 2018, we carried out a three-week block of work to install electrification equipment between Patchway station (west of Bristol Parkway) and The Severn Tunnel. This involved:
- Lowering the track in the Old Patchway Tunnel
- Installing electrification equipment inside the Old and New Patchway Tunnels
- Installing masts and gantries on the open line between Patchway and The Severn Tunnel, through Pilning
- Installing wires on the masts and gantries.
The upgrade was completed successfully, marking a significant milestone in our work to electrify the line between London and Cardiff. For more information about what was achieved, please see our Twitter feed: #SummerTunnels
We will be continuing our work in this area between 24 December and 1 January 2019.
We know that our work to improve the railway may cause some disruption and noise for local communities. We do our very best to limit this and appreciate your patience and understanding.
For example, we often have to carry out some of the work at night when trains aren’t running. This is because we’re contractually obliged to work at times that have the least impact on passenger services, and because we must ensure the safety of our workforce.
If roads or footpaths need to be closed temporarily because of bridge work, we agree diversionary routes with the local council. And we are committed to completing the work quickly, so the road can be re-opened as soon as possible.
