The North Downs Line is a railway line in South East England. It runs for 41 miles 40 chains (66.8 km) from Reading in Berkshire to Redhill in Surrey. It is named after the North Downs, a range of chalk hills that runs parallel to the eastern part of the route. The name was introduced in 1989 by Network SouthEast, the then operator. The North Downs Line serves the settlements in the Blackwater Valley as well as the towns of Guildford, Dorking and Reigate. It acts as an orbital route around the south and southwest of London and has direct connections to the Great Western Main Line at Reading, the Waterloo-Reading line at Wokingham, the Alton line at Ash, the Portsmouth Direct Line at Guildford and the Brighton Main Line at Redhill.

The River Blackwater is a tributary of the Loddon in England and sub-tributary of the Thames. It rises at two springs in Rowhill Nature Reserve between Aldershot, Hampshire and Farnham, Surrey. It curves a course north then west to join the Loddon in Swallowfield civil parish, central Berkshire. Part of the river splits Hampshire from Surrey; a smaller part does so as to Hampshire and Berkshire.
