The Raurimu Spiral is a single-track railway spiral, starting with a horseshoe curve, overcoming a 139-metre (456 ft) height difference, in the central North Island of New Zealand, on the North Island Main Trunk railway (NIMT) between Wellington and Auckland. It is a notable feat of civil engineering, having been called an "engineering masterpiece."[1] The Institute of Professional Engineers of New Zealand has designated the spiral as a significant engineering heritage site.[2]
