North Island main trunk line: Raurimu spiral (1st of 3)

The Raurimu spiral is the North Island main trunk line's most impressive engineering feat. The land rose sharply between National Park and Raurimu. Laying the track in a spiral formation and running it through tunnels allowed trains to gain the necessary altitude. This clip from the 1981 television series Landmarks, presented by geographer Kenneth Cumberland, explains the spiral's design.
