The Elham Valley Railway was a line connecting Folkestone and Canterbury in Kent, England. It opened between 1887 and 1889 and closed in 1947. The line was originally proposed by the independent Elham Valley Light Railway Company in the mid-19th century. After the project was cancelled owing to financial difficulties, it was revived by the South Eastern Railway who were competing with the rival London, Chatham and Dover Railway for railway traffic. The scheme was complicated by the imposing geography of the Elham Valley and the construction of two significant tunnels. The southern section from Cheriton to Barham opened in 1887, with the northern section to Canterbury opening two years later.
