Remutaka Tunnel
The 117th longest tunnel in the world
The Remutaka Tunnel (spelled Rimutaka Tunnel before 2017) is a railway tunnel through New Zealand's Remutaka Range, between Maymorn, near Upper Hutt, and Featherston, on the Wairarapa Line. The tunnel, which was opened to traffic on 3 November 1955, is 8.93 kilometres (5.55 mi) long. It was the longest tunnel in New Zealand, superseding the Otira Tunnel in the South Island until the completion of the Kaimai Tunnel 9.03 kilometres (5.61 mi) near Tauranga in 1978. Remutaka remains the longest tunnel in New Zealand with scheduled passenger trains.
