From the Karamea end of the coast we went to the old Denniston mine and the incredible down hill cable rail for the coal wagons to come down from the mine full of coal.
Lorries then took the coal to the railway siding for moving on to the Westport Port for shipping around New Zealand. All equipment, horses and people used the coal wagon cable rail to get to and from the coal field which was on a high plateau. Very early on a school inspector refused to use the coal wagon “hauled by a thin wire cable that had previously failed” so the school wasn’t inspected.
Some wives taken up to the plateau didn’t come down for 20 years!
