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.

More about our work to electrify the railway

Royal Wootton Bassett

The A3102 in Royal Wootton Bassett is due to reopen to traffic on 20 April 2017, following the reconstruction of the Bath Road bridge. The temporary link road will close to traffic once the A3102 has reopened.  The work has created the additional space required for the electrification of the line.

Further work is required to raise the parapets, or sides, of the adjacent Hunts Mill bridge, which will take place overnight under temporary traffic lights from 8 May- 15 May 2017 inclusive.

The track underneath Hunts Mill bridge needs to be lowered to make way for the overhead power lines. The work will take place over the weekends of 27-29 May and 10-11 June 2017.

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.
