The "Invicta" locomotive was retired in 1840 and replaced by horses until a third winding engine was built at South Street. The "Invicta" was kept for scrap, but in 1898 work began on its restoration, which continued intermittently until its completion in 1977 by the National Railway Museum in York. On 3 May 1980 the locomotive was returned to Canterbury to celebrate the 150th anniversary of the line. On Sunday June 16th 2019 Invicta was returned to the Whitstable Museum & Gallery.
