Kemp Town branch line was a railway line running from Brighton to Kemptown in the UK that operated between 1869 and 1971. It ran from a junction off the Brighton to Lewes line between London Road and Moulsecoomb stations, to Kemp Town railway station. It opened in 1869 and was expensive to construct, requiring a tunnel and a large viaduct.

The East Coastway line is a railway line along the south coast of Sussex to the east of Brighton, England. Trains to the west of Brighton operate on the West Coastway line. Together with the West Coastway and the Marshlink line to the east, the line forms part of a continuous route from Havant to Ashford. The Brighton Main Line route to Eastbourne and Hastings, via Plumpton and Cooksbridge, shares the East Coastway line east of Lewes station.
