 Following the railway grouping of 1923 , both the South Eastern Railway and the London , Chatham & Dover Railway became part of the newly formed Southern Railway , which decided to address the duplication of lines and stations at Ramsgate and Margate . It decided to link the two lines at Ramsgate to allow through running between them . This scheme had been proposed by the South Eastern and Chatham Railway before World War I , but work did not commence until 1925 . This meant the closure of the terminus stations at Ramsgate Town and Ramsgate Harbour , and the construction of a line skirting the northern edge of the town to link the two existing lines . New stations on the north @-@ eastern and north @-@ western fringes of the town , called Dumpton Park and Ramsgate respectively , replaced the existing stations in the town centre and at the harbour . Construction work on the new line involved over 700 men moving 200 @,@ 000 long tons ( 224 @,@ 000 short tons ; 203 @,@ 200 t ) of chalk , at a cost of approximately £ 500 @,@ 000 ( £ 26 million in 2016 ) .
