Class 20’s from Boulby Potash

This looks a very modern photograph, about mid-1980’s we’re informed.  The locomotives are BR Class 20s, 20165 (from 19878 till 1980 named ”Henry Pease” – how ironic!) and possibly 20118 (latterly named ”Saltburn-by-the-Sea”) – they typically operated ”nose-to-tail” as in this image.  With these big arrows they could have been blue with yellow ends, or, even later, grey with yellow ends. On the right of this image is the Guibal fan house at the base of Warsett Hill, Brotton; the only surviving  remnant of  the Huntcliffe Ironstone Mine.
