Why is it that only tourists are foolish enough to travel on the roof of a train while the locals tuck themselves away safely in the carriages ? The view below me is from the journey from Alausi down to Devil's Nose along a precarious piece of zig-zag engineering. Taken while we were 'zigging' , you can just see the section of track which is the next 'zag' and right at the bottom the final 'zig'.
