We’re delivering £60m of investment on the South Wales Mainline with the installation of a new state of the art signalling system from Port Talbot to Swansea.
This major upgrade project includes a new signalling system between Cockett Tunnel (west of Swansea Station) and Baglan (west of Port Talbot), as well as upgrading track, power supplies and telecoms equipment. This will increase the resilience, flexibility and reliability of the railway in South Wales.
The new signalling system comprises of 55 new LED signals, which will control all train movement on this line. All of this is powered by a new supply – which required the provision of new electrical supply points. This system includes built-in standby generators and additional emergency generator bases to enable rail services to be maintained in the event of any power failures, making the railway more resilient for passengers. Work commenced on the project in 2017.
Enhancement works at Briton Ferry included the installation of two sets of points unlocking the capability for bi-directional signalling between Port Talbot and Swansea. This allows the railway traffic to be operated in either direction, improving the flexibility and resilience of the railway. Four new buffer stops and 160 metres of track were installed at Swansea station increasing the available platform lengths to accommodate new trains.
The new state of the art signalling equipment was commissioned in March 2019 and is set to be completed by the end of summer 2019.
Over three miles of track has been reprofiled and 22,000 tonnes of new ballast installed between Neath and Llansamlet.
