The line was originally signalled by a mixture of semaphore signals and colour lights by several signal boxes over the years. Almost every station had a signal box, Lewes even had five signal boxes controlling the area including the goods yard. Polegate had three signal boxes and other signal boxes at Willingdon and Stone Cross junctions and at Pevensey Bay and Cooden Beach There were also crossing boxes at Ripe, between Glynde and Berwick, and at Wilmington, between Berwick and Polegate.
