I have ridden on the Darjeeling Himalayan Railway
, so I'm not easily impressed by spirals, zigzags, and the like. But I was impressed by this view of the Raurimu spiral. Railway enthusiasts have built a platform for viewing the path of the railway through cuttings and tunnels. Close to the platform is a clever model, standing on a pole, showing the hairpin turns and tunnels and showing the whole scheme in the round. A panel with a map explains the background:
Here in 1898 W Holmes carried out surveys and devised the spiral alignments whereby the railway ascends from this valley to the Waimarino plain 220 metres above. John Rochfort's original survey 15 years earlier had broadly defined the route but had left unresolved the problem of a working grade for this section.
