Network Rail has confirmed that phase two of the Port Talbot West resignalling project is to start this month.

The work will continue until October. Commissioning will then take place in November, which will bring the new system into use, with a promise from Network Rail that it will make the railway safer, more reliable and more convenient.

Some sections of the railway and roads will need to be closed in order to allow workers to complete the work safely.

There have been 59 signalling failures between Carmarthen and Llanelli over the last two and a half years. Network Rail intends that the upgraded signalling and level crossing systems included in this programme of work will address this issue.

It explains that by improving infrastructure, updating safety and streamlining operations, it will reduce the frequency and duration of delays to both passenger and freight services.

The work includes upgrades between Carmarthen and Pembrey, including upgrading several level crossings.

Level crossing safety will be addressed by installing obstacle detectors, which monitor crossings and issue alerts in response to potential hazards.

It also involves the decommissioning of signal boxes at Pembrey, Kidwelly, Carmarthen and Ferryside. The boxes’ operations will be taken over by a central hub in Port Talbot. Signalling systems have been similarly concentrated in a central hub at various other locations in the UK, in an approach designed to make railway traffic management faster and more efficient. For example, signalling operations on the East Coast Main Line are being transferred to a new, modern signalling centre at York, and signalling in south west London has transferred to the Basingstoke Rail Operating Centre.

Network Rail will also be renewing track at Ferryside and upgrading the crossing surface to make it safer and more durable.

“This is a transformative moment for rail operations in South West Wales. By centralising control and upgrading our signalling infrastructure, we’re not only improving reliability but also laying the groundwork for a safer and more responsive railway system that better serves our communities.

“We thank passengers in advance for their patience while this vital work is carried out.”
