 When the HB&HR opened, its line was simply a southward branch at Haddiscoe, from the Lowestoft Railway and Harbour company's line from Reedham to Lowestoft.When the company closed the line to double it and connect the Lowestoft and Yarmouth line, and re-opened as the East Suffolk Railway, the junction was naturally reconfigured.The main route ran north to south from Yarmouth, crossing over the Lowestoft Railway.
