Wiltshire and Swindon

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

The following film below marks the start of electric services between London Paddington and Swindon in November 2018. This was a crucial milestone in our project to electrify the railway between London and Cardiff, paving the way for longer, quieter, cleaner trains.

Trowbridge track renewal

In order to keep the railway running smoothly and safely, we periodically need to repair and replace the track and other infrastructure.

In the Trowbridge area, we will be working to replace a section of the line between Trowbridge Station and the aqueduct to the north of the town, that carries the Kennet and Avon canal over the railway.

This involves cutting, lifting and removing the old track before laying new track stones (ballast) and then installing and welding the new sections of track. We then pack and compact the track stones (tamping) to improve stability. This optimises the track, improving comfort for passengers, reducing wear on the rails and reducing the amount of noise caused by passing trains.

To complete this crucial renewal, we will be working throughout three full weekends in April and May, as well as a number of Saturday nights between April and June. The job will also require some midweek working at the end of May.

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.
