Project Information:

Network Rail are electrifying the line between London and Cardiff – a major part of the Railway Upgrade Plan. This will result in the introduction of bi-mode trains – trains that can run on electric and diesel – providing extra seats and faster services for thousands of passengers and a quieter and greener environment for lineside neighbours. The South Wales Mainline runs from the Severn Tunnel in Monmouthshire, through Newport, Cardiff, Bridgend, Port Talbot, Neath and Swansea.
