History
The line was originally part of the Wellington - Manawatu Line built by the Wellington and Manawatu Railway Company. The line to Paremata station, which was close to the Paremata Barracks ruins, was opened on 21 September 1885, without ceremony. The first train with 59 people aboard had three composite coaches and a van. Cobb & Co built stables at Paremata, and from October 1885 an early train leaving town at 7 a.m. made it possible to travel from Wellington to Wanganui in one day by rail and coach. The line was extended to Plimmerton in October, and Pukerua Bay by the end of the year. The line was extended to Paekakariki in 1886, and was electrified in 1940 after the opening of the Tawa Flat deviation. Double tracking north to Mana was opened on 7 November 1960, and the original station built in 1885 by the WMR was replaced by a new one across on south side of the Pauatahanui Inlet entrance. The original station yard had a large freight shed built in World War II for the American forces in the district, but postwar there was little freight traffic, and the yard was not replaced. The new station on reclamation for the new bridge embankment was nearly ten feet higher than the old yard.
