this was done a while back but i fort id still share it with you guys
The London Chatham & Dover Railway Company opened their extension from Margate to a terminus at Ramsgate Harbour in 1863. The last section of the line ran in a 1124 yard tunnel from Dumpton Park to the terminus on the seafront, close to the harbour. In 1926, Southern Railway built a link from their line at Dumpton Park to the former South Eastern Railway station at Ramsgate Town, a mile inland. The link was built because of cramped conditions at the terminus and the steep gradient which caused some difficulty for steam locomotives. The Harbour Station and the tunnel were closed from 2nd July that year.
