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.
Lady St Margaret footbridge in Sandgate, Swindon, reopened in July 2018 following the completion of work to raise the parapets, or sides, of the bridge as part of our project to electrify the railway between London and Cardiff.
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.
