The earliest of the London - Dover main lines, built by the South Eastern Company, incorporated in 1836 and completed by 1844. The route ran from Dover to Folkestone and Ashford, and then virtually straight through the Vale of Kent to Redhill via Tonbridge. The approach to London used the South Eastern 's track between Redhill and Stoat's Nest, then the London and Brighton's line to the Jolly Sailor, the London and Croydon's line to Corbett's Lane, and the London and Brighton's line to London Bridge.
