The Taff Vale Railway was a railway line in South Wales, established in the 19th century. It primarily served the coal and iron industries, connecting the South Wales Valleys to the port of Cardiff. The railway played a crucial role in transporting goods and passengers, contributing to the region's industrial growth. Opened in 1836, the Taff Vale Railway was one of the earliest railways in Wales. It expanded over the years, eventually becoming part of the Great Western Railway network. The line's development significantly impacted local communities and the economy, facilitating trade and mobility in the area.
