The Helston Railway is a heritage railway in Cornwall which aims to rebuild and preserve as much as possible of the former GWR Helston Railway between Nancegollen and Water-Ma-Trout on the outskirts of Helston. It is operated by the Helston Railway Preservation Company using members of the Helston Railway Preservation Society. It was built to open up the agricultural district of south-west Cornwall, joining Helston to the main line railway network at Gwinear Road, between Penzance and Truro.
