Wiltshire and Swindon

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 Wiltshire and Swindon and when it's due to take place.

Over Christmas 2016, the A3102 bridge in Royal Wootton Bassett was demolished and partially reconstructed (see video below). The new bridge is higher, creating the additional space needed for the overhead electrification wires that will power the new fleet of faster, longer, quieter and greener trains on the Great Western route.


Upgrading the railway in Wiltshire and South Gloucestershire

From 19 August to 15 September 2017, our orange army worked day and night along the railway between Royal Wootton Bassett, Wiltshire, and Patchway/Filton junctions, South Gloucestershire.

As part of the Greater West Programme, we are electrifying the line to bring passengers quieter, more frequent and more reliable services between London Paddington and Cardiff.

What we're doing

To enable the route to be electrified. we're installing supporting masts and overhead lines, and preparing the foundations for these ('piling'). We'll also be modifying some of the bridges and other structures on the route to create the extra height needed for the overhead lines.

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 reopened as soon as possible.
