A unique railway spiral and loop system with two tunnels.
The railway had to drop 700 feet in 4 miles, from an altitude of 2,663 feet at National Park, to 1,934 feet at Raurimu. The maximum gradient planned for on this line was 1:50 and the straight line gradient from National Park to Raurimu was 1:29!
Creating the spiral was the only way to get down the edge of the volcanic plateau.
No better way has been found.
