I've been asked to confirm that the Tyne is the location of this photo, probably taken around 1970.
I'm just not sure. These cranes look a bit different to those shown in pictures of the ore quay that I've found so far.
Anyone care to comment?
While looking for inspiration I came across a short but interesting piece of film on the Yorkshire Film Archive site which shows an ore carrier arriving in the river, and shots taken on board the ship at the ore quay. There are also some clips of ore trains, with 9F's, Q6's and Q7's in harness. Lovely stuff!
