The passenger service on the line was interrupted in both World Wars: it closed from 2 April 1917 "for security purposes", reopening on 1 November 1917. During the Second World War passenger services were withdrawn once again for "security reasons". The railway closed on 1 January 1940 and reopened on 9 February 1942; it closed again on 24 August 1942 and reopened on 3 October 1942; it closed again on 2 May 1944 and reopened on 2 October 1944 after the D-Day landings had happened. The World War II period also enabled reuse of sidings at Woodgate Pill near Fowey. These were used for a munitions store. Never heavily used, the passenger service from Lostwithiel to Fowey was withdrawn on 4 January 1965, and the line now carries only mineral traffic to Carne Point. The CMR line from Par to Fowey closed on 1 July 1968, and the Lostwithiel and Fowey route is now the only rail route to Fowey.
