And then Photoshopped as well. I like it, anyway.
It's the Zig Zag Railway near Lithgow, NSW, Australia, btw. Before the railway cut through the Blue Mountains like power-crazed engineers are wont to do, they zig-zagged their way up the steep bits instead. A bit slow to traverse in this manner but a lot easier than boring long tunnels and slicing deep cuttings into the rock (which of course they ended up doing later anyway).
