This arrangement was inherited by Southern Railway on grouping in 1923. In 1926 a new line was opened connecting the SER line from east of Ramsgate Town to the LCDR line just south of Broadstairs. The current Ramsgate station and a new station at Dumpton Park were built on this new line. The Ramsgate Harbour station, line through the tunnel, and the Ramsgate Town station and old SER line across to Margate Sands were all closed in July 1926. This change made for operational convenience, but has the disadvantage that the town centre is no longer served.
