Wiltshire and Swindon

We're modernising the Great Western route to bring passengers faster, more frequent and 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.

The demolition and partial reconstruction of the A3102 bridge in Royal Wootton Bassett over Christmas, 2016. The new bridge will be 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.


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.

Royal Wootton Bassett

The Broad Town/Marlborough Road bridge has reopened to traffic following its reconstruction. We are now working on the Bath Road and Hunts Mill bridges on the A3102 until early spring in order to prepare them for the new fleet of electric trains. During this time, vehicles will need to follow a signed diversion route.

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.
