South Gloucestershire

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 timelapse film shows two 44m booms being installed just outside Bristol Parkway station during our autumn upgrade. They will support the wires that will enable the new fleet of Intercity Express Trains to run on electricity in 2019.

Swindon to Bristol Parkway station

This year, we will be finishing electrification of the railway line from London to Bristol Parkway.

Between 15 September and 7 October, we installed electrification equipment, including masts, booms and wires, between Winterbourne and just west of Bristol Parkway station. We also completed and tested equipment already installed between Royal Wootton Bassett and Winterbourne.

The work will enable trains to run under electric power between Swindon and Bristol Parkway in 2019.

Further testing work will be taking place night and day over the weekend of 13-14 October and from Monday 15 October to Thursday 18 October (inclusive) between 22:30 and 05:00.

On 13-14 October, we will also be working on our project to double the number of tracks between Filton Abbey Wood and Bristol Temple Meads.

How journeys will be affected

Over this weekend, trains will not run via Bristol Parkway or between Bristol Parkway and Bristol Temple Meads (including the Severn Beach line). Trains may be diverted or replaced by buses. Please check before you travel.

Saturday 13 - Sunday 14 October

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.

Filton Abbey Wood Update letter

Footpath reopened

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.

Working responsibly

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.
