Atherington Victoria & East Yard.

In case you haven't spotted them there are photos of aggregate depots in Newhaven in this thread, that you may find interesting. They are both fairly small rail-served depots, with a mix of dredged shingle aggregates in both and quarried stone in the northern, Day's Aggregates one. The new East Quay depot has some different wedge shaped bin dividers.

Please accept my apologies for taking so long to reply.  Clearly, I have something wrong with my 'settings' and 'Notifications', as I was not informed of your kind comment.  It was the Newhaven traffic (and seeing writings of Eastbourne's Crumbles shingle extraction many years ago) of which I was thinking, when building the aggregates yard.  I did not know the modern Newhaven depots held quarried stone as well.  I admit I avoided their designs as being 'too new', rather than the declining 1970's aesthetic I am after.  However, I should use them as the basis for the minerals' colours if nothing else: my multi-cloured 'shingle' is a little too red, compared to my childhood memories of Sussex beaches sprinkled with orange pebbles.  Something to re-do later.  Many thanks again for all your contributions.
