Environmental Responsibility: Electric trains produce 20% to 35% fewer carbon emissions than diesel equivalents. Unlike bi-mode trains, they have zero emissions at the point of use, significantly improving air quality in urban hubs like Swansea and Neath.
Economic Growth: Rail demand between Swansea and London is forecast to increase by 142% over the next 25 years. For too long, the rail network in Wales has been treated as a collection of "branch lines" rather than a vital national asset. While multi-billion pound projects are greenlit elsewhere, Wales has been systematically "starved of investment," leaving our passengers with a 19th-century infrastructure. The "England & Wales" Classification of Major projects like HS2, Northern Powerhouse Rail have been classified as "England and Wales" projects despite not having a single inch of track in Wales. This classification allows the UK Treasury to bypass the Barnett Formula, which would otherwise grant Wales billions in consequential funding.
