The Monmouthshire Railway was a railway line in Wales that operated in the 19th century. It was established to connect the towns of Monmouth and Chepstow, facilitating the transport of goods and passengers. The railway played a significant role in the local economy by improving access to markets and resources. Opened in 1857, the Monmouthshire Railway was part of a broader network that contributed to the industrial growth of the region. It eventually became part of the Great Western Railway system, which expanded rail services across Wales and England. The line was closed to passenger services in the mid-20th century.
