They look the part!! I moved to Ouston in the late seventies our house overlooked the main line when I saw them for the first time I remember thinking I wish I'd seen them with a 9F in front instead of a diesel, I was more interested in the Deltics, then in their last years and the H.S.T's still then very new.I wish I had bothered to photo the hoppers then as within a year or two Consett steel works ceased to be.The benefit of hindsight!! The mainline at Birtley was always busy stuff in and out of Tyne yard
