Reliant on closure of the line, a proposed Folkestone Harbour and Seafront Masterplan included plans to demolish the viaduct to make way for a new marina. An association opposing the closure was formed, with the primary aim of gaining control of the branch either through purchase or a lease with an option to buy. The group, called the "Remembrance Line Association" proposes turning it into a mainline connected heritage railway, a 'Leaving for War' museum and a memorial dedicated to the troops that arrived on trains to the branch and left on ships to fight in both World War I and World War II. It also proposes hosting regular national railtours to the branch, and would permanently operate a tourist shuttle service up and down the 1in30 gradient, utilising its own rolling stock and locomotives. Further plans include a revived passenger ferry to Boulogne. On 21 December 2008, the Remembrance Line Association ran a railtour to the branch using the Southern Railway preserved diesel electric Class 201 No. 1001.
