The West Cornwall Railway was a railway company in Cornwall, Great Britain, formed in 1846 to construct a railway between Penzance and Truro. It purchased the existing Hayle Railway, and improved its main line, and built new sections between Penzance and Hayle, and between Redruth and Truro, and opened throughout in 1852. When the Cornwall Railway reached Truro in 1859, rail travel between Penzance and London was possible, by changing trains. The main line of the West Cornwall Railway is still in operation at the present day, forming the western end of the Cornish Main Line railway.
