The railway from Wellington to Paekākāriki opened on 3 November 1886 as part of the
Wellington-Manawatu Line built by the
Wellington and Manawatu Railway Company (WMR). Before 1905, the name was spelt
Paikakariki. The official name of the town was changed to Paekākāriki (with
macrons) by the
New Zealand Geographic Board on 21 June 2019. The first
Auckland - Wellington through expresses ran on 14 February 1909, taking 19 hours 13 minutes, and stopping at Paekākāriki. Following the completion of the
Tawa Flat deviation on 19 June 1937, electrification of the railway from Wellington to Paekākāriki was completed on 24 July 1940 allowing electric locomotive-hauled commuters carriage trains to operate between Wellington and Paekakariki.
DM/D class multiple units were introduced in the 1950s and replaced most locomotive-hauled carriage trains. From the completion of the electrification to Paekākāriki in 1940, steam locomotives were not permitted to work south of Paekākāriki due to the smoke nuisance in the long tunnels on the Tawa Flat deviation. Long-distance passenger and freight trains were hauled by
ED and
EW class electric locomotives between Wellington and Paekākāriki where the locomotives were changed from electric to steam. During the 1950s, steam locomotives were progressively replaced by diesel-electric locomotives for long distance trains, but locomotives continued to be changed at Paekākāriki because the new
DA class diesel locomotives were initially unable to operate south of Paekakariki due to the limited clearances in the tunnels between
Pukerua Bay and Paekākāriki. Work was undertaken to lower the floors of these tunnels to improve clearances and from the 1960s diesel locomotives were able to work south of Paekākāriki and locomotive changes at Paekākāriki became unnecessary. However, electric locomotives were kept at Paekākāriki to bank trains that needed assistance on the steep grade from Paekākāriki to Pukerua Bay. In the 1980s, the purchase of additional multiple units and more powerful diesel locomotives allowed the electric locomotives to be withdrawn from service. A deviation was built around Tunnel 12 in the early 1900s and a fence to protect from landslides was built after a derailment in 1980. Electrification was extended north of Paekākāriki to Paraparaumu: the section officially opened on 7 May 1983 allowing the extension of suburban commuter service to Paraparaumu which became the new northern terminal for suburban commuter services. Before 1983 there were buses from Paekākāriki to Paraparaumu and Raumati. The station previously had a
refreshment room and a steam locomotive depot. The refreshment room closed when it became unnecessary to stop trains to change locomotives at Paekākāriki. Locomotives were changed or a banker locomotive added for the steep bank up to Pukerua Bay, and from 1940 it was the southern terminal station for steam locomotives. Previously there was a signal box at each end of the station, a two-road shed with water, coal and oil facilities, a turntable, and (until
Wellington Airport was opened) a rail/air freight depot for
Paraparaumu Airport. The
Paekakariki Station Precinct Trust works "to acquire, develop, and administer the venue of the Railway Station Precinct at Paekākāriki for recreational, historical preservation, tourism, and educational purposes, and for other allied or supporting activity". ==See also==
