Three types of stone walling. Note also the sticks holding up a piece of barbed wire.
This is supposed to stop sheep from scaling the walls and getting on the tracks!

indentThere are three distinct types of stone walls here; the massive structure of the viaduct, the "rubble walling" embankment support and some of the 100+ mouldings of dry stone wall I created and used!  The viaduct was also made from my own mouldings but the rubble wall was carved with a scalpel from a roughly applied layer of car body filler.
