 The proposal would involve re-aligning the railway, moving the line further from the cliff and creating a space between them to prevent the railway's being affected by cliff subsidence or collapse.Other elements of the proposal include the improvement of the sea wall between Kennaway Tunnel and Dawlish and the installation of an avalanche shelter-style structure at Horse Cove.Government funding of £80 million to raise the sea wall south of Dawlish station by was approved in February 2019.
