The twin towers of Whitehaven, taken from Whitey Rock, all the features on the seaward side of the railway in this image have been destroyed in stormy weather since approx 2015, although the slag heap next to the pillars was gone before then.
The features in the cliff above the loco are, I think, for WW2 searchlight / gun spotters positions - they would be for the guns at Bransty, on the hill above, for protecting the Harbour entrance.
