Single track railway from Hoo Junction on the North Kent Line to Port Victoria on the Isle of Grain. Passengers alighting at Port Victoria caught a ferry across to Queenborough to connect with the Dutch Steamers. The line opened in 1882 but never flourished. The ferry ceased to operate in 1901 and in 1916, Port Victoria pier was closed due to decay. Only high freight receipts kept the line profitable after World War I. Despite a double track branch line to Allhallows opening in 1932, the attempt to turn Allhallows into an attractive resort failed and the branch line closed in 1961. The opening of the Isle of Grain oil refinery in 1951 gave the line a new lease of life, and it continues to transport oil to and from the refinery.
