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 only railways to do so since Pakistan's Khyber Pass Railway closed.
