Palmerston North–Gisborne Line

The Palmerston North–Gisborne Line (PNGL) is a secondary main line railway in the North Island of New Zealand. It branches from the North Island Main Trunk at Palmerston North and runs east through the Manawatū Gorge to Woodville, where it meets the Wairarapa Line, and then proceeds to Hastings and Napier in Hawke's Bay before following the coast north to Gisborne. Construction began in 1872, but the entire line was not completed until 1942. The line crosses the runway of Gisborne Airport, one of the world's few railways to do so since Pakistan's Khyber Pass Railway closed.

In conjunction with the Moutohora Branch that ran north from Gisborne between 1900 and 1959, the line was originally intended to connect to the East Coast Main Trunk, described in 1875 as the North Island trunk line, but the difficult inland section between the Tāneatua Branch in the Bay of Plenty and the Moutohora Branch was never completed.

The line has not carried passenger trains since October 2001, when the Bay Express service was cancelled. The northern portion of the line, from Napier to Gisborne is currently inoperative due to damage from Cyclone Gabrielle in 2023. The section was mothballed north of Wairoa due to four significant washouts during a storm in March 2012. The whole Napier–Gisborne section was officially mothballed (but not closed) in December 2012. The Napier–Wairoa section reopened for forestry traffic in June 2019, but has been mothballed again following Cyclone Gabrielle. The section between Wairoa and Gisborne has suffered from further slips and washouts since 2012. The Gisborne City Vintage Railway has a lease agreement over the Gisborne to Muriwai section of the line, which it uses for its seasonal vintage trains.
