Railway line in New Zealand running between Auckland and Wellington

The North Island Main Trunk (NIMT) is the main railway line in the North Island of New Zealand, connecting the capital city Wellington with the country's largest city, Auckland. The line is long, built to the New Zealand rail gauge of and serves the large cities of Palmerston North and Hamilton. Most of the NIMT is single track with frequent passing loops, but has double track

between Wellington and Waikanae, except for of single track through tunnels between North Junction ( from Wellington) and South Junction, ( from Wellington), on the Pukerua Bay to Paekākāriki section,
between Hamilton and Te Kauwhata (except for the single track Waikato River Bridge at Ngāruawāhia), and
between Meremere and Auckland Britomart. Around (approximately 65%) of the line is electrified in three separate sections: one section at 1500 V DC between Wellington and Waikanae, and two sections at 25 kV AC: between Palmerston North and Te Rapa (Hamilton) and between Papakura and Auckland Britomart. The first section of what became the NIMT opened in 1873 in Auckland. Construction at the Wellington end began in 1885. The line was completed in 1908 and was fully operational by 1909. It is credited for having been an economic lifeline, and for having opened up the centre of the North Island to European settlement and investment. with numerous engineering feats such as viaducts, tunnels and a spiral built to overcome large elevation differences with grades suitable for steam engines, the ruling gradient being 1 in 50.

When the first sections of the NIMT were built, there was great uncertainty as to even the route in Waikato, with Cambridge, Kihikihi, Te Awamutu and Alexandra considered as possible destinations in Waikato. The central section was gradually extended to meet up in 1909, 23 years after the last of the northern and southern sections of NIMT had been opened.

Auckland's first railway was the line between Point Britomart and Onehunga via Penrose, opened in 1873. It was built by Brogdens, as was the rest of the Auckland & Mercer Railway, for £166,000 for the 41 mile (66 km) to Mercer. The section from Penrose to Onehunga is now called the Onehunga Branch. The line was later continued south from Penrose into the Waikato. To support the Invasion of the Waikato, a 3.5 mile (6 km) tramway was built from Maungatāwhiri to Meremere in 1864, with a first sod event near Koheroa on Tuesday, 29 March 1864 by Auckland's Chief Superintendent of Roads & Bridges, W R Collett. Turning of the first sod of the Auckland and Drury Railway took place in 1865, a year after the last major battle. This line reached Mercer by 20 May 1875, with from Ngāruawāhia being constructed by the Volunteer Engineer Militia and opened on 13 August 1877. It was extended to Frankton by December 1877, and to Te Awamutu in 1880. An economic downturn stalled construction for the next five years, and Te Awamutu remained the railhead. There were also negotiations with local Māori, and the King Country was not accessible to Europeans until 1883.

The Wellington Longburn (near Palmerston North) section was constructed between 1881 and 1886 by the Wellington and Manawatu Railway Company (WMR). The company was acquired by the government and merged with the New Zealand Railways Department in 1908. The Longburn to Marton section had been opened on 18 April 1878, as part of the line linking the ports of Foxton and Whanganui.

In 1882, the Whitaker Ministry passed the North Island Main Trunk Railway Loan Act, to expedite construction of the North Island Main Trunk south of Te Awamutu by authorising the overseas borrowing of a million pounds (probably in London) for the work. From Te Awamutu, it was proposed that the line be built via Taupo or via Taumarunui, the eventual route. Four options were considered before the Minister of Public Works decided on the present route in 1884, but, when it was realised just how difficult that route was, further surveys considered two other options in 1888. Construction of the final central section began on 15 April 1885, when paramount chief Wahanui of Ngāti Maniapoto turned the first sod outside Te Awamutu. But much of the new section was temporary, with some cuttings north of Taonui having vertical batters and unballasted track from Horopito to Makatote. Ward drove the last spike on 6 November 1908, and the 'Last Spike' monument is at Manganui o te Ao , near Pokaka. A two day NIMT service started on 9 November, with an overnight stop at Ohakune. On 14 February 1909, the first NIMT express left Auckland for Wellington, an overnight trip scheduled to take 19 hours 15 minutes, with a sleeping car, day cars with reclining seats, and postal/parcels vans. The dining car went on the north express from Wellington to Ohakune, then transferred to the southbound express, so avoiding the heavy gradients of the central section.

The rails and signalling have been upgraded over the years, and many sections of the line have been deviated: The original 1870s Vogel Era track had rails of 40 lb/yd (19.9 kg/m), some were iron not steel; later rails were 53 lb/yd (26.3 kg/m); and from 1901 70 lb/yd (34.8 kg/m), e. g. between Taumarunui and Taihape for the heavy X class locomotives used on the central mountainous section from 1908. Some 10 bridges between Frankton and Taumarunui had to be strengthened, and in 1914 there was still 129 km (80 mi) of 53 lb/yd rail to be replaced. In the 1930s 85 lb/yd (42.2 kg/m) was adopted, then 91 lb/yd (45.1 kg/m), and from 1974 100 lb/yd (50 kg/m). Signalling on the single track sections (most of the line) was controlled by Tyer's Electric Train Tablet No 7 system; with each of the stations for the 94 tablet sections staffed by three tablet porters each working a 56 hour week for continuous coverage; hence each station required at least four houses for the stationmaster and three porters. Pierre noticed that with CTC station buildings and even platforms had been removed as there were no longer any staffed stations between Ohakune and National Park. The Train Control system introduced from 1928 to 1932 supplemented the tablet system by operators at the four sections (Auckland, Frankton, Te Kuiti, Ohakune, Marton and Wellington) to expedite operation of trains over several tablet sections; the 1925 Fay Raven report urged its adoption because of the fitful progress of mixed trains, with locomotives often kept waiting. From 1938 to 1966 Centralised Traffic Control (CTC) gradually replaced the tablet system on the NIMT. In 1957 when the installation of CTC over the remaining commenced, it was estimated that using CTC over the Taumarunui to Otaki section with control centres at Ohakune (which shifted to Taumarunui in 1977), Taihape and Palmerston North would replace 74 men in traffic working duties. The last section converted was Piriaka Owhango. A 1926 article by "Backblocks" described conditions for staff at these stations where four workers lived in isolated areas, and their efforts to get special trains for transport to special events. In 1913, the maximum speed limit on the NIMT was raised to , reducing the journey time by 1 hour 25 minutes Auckland Wellington or to 17 hours and between 30 and 45 minutes. Under Thomas Ronayne, the New Zealand Railways Department general manager from 1895 to 1913, the section south to Parnell was duplicated and improvements made to the worst gradients and tight curves between Auckland and Mercer. Under his successor E. H. Hiley the second Parnell Tunnel with two tracks and an easier gradient was completed in 1915–1916. On the Kakariki bank between Halcombe and Marton a deviation reduced the 1 in 53 grade to 1 in 70 in 1915. Similar work was done to ease the gradient to Greatford, on the other side of the Rangitīkei River, in 1939. A 1914 Act authorised spending on the Westfield Deviation, new stations at Auckland and Wellington, track doubling (Penrose Papakura, Ohinewai Huntly, Horotiu Frankton, Newmarket New Lynn), and grade easements from Penrose to Te Kuiti, but the war delayed most of these works for over a decade. In 1927, automatic colour light signalling was installed from Otahuhu to Mercer. In 1930 the signalling was extended 34 mile (55 km) to Frankton and the 6 mile (10 km) from there to Horotiu was doubled. The 3 mile (5 km) north to Ngāruawāhia was doubled from 5 December 1937, followed by 9 mile (14 km) Ngāruawāhia to Huntly on 4 December 1938 and Huntly to Ohinewai and Papakura to Paerata in December 1939. By then, wartime shortages delayed further double tracking. Pokeno to Mercer was doubled from 11 November 1951, Pukekohe to Pokeno 21 November 1954, Mercer to Amokura 1 July 1956 and Ohinewai to Te Kauwhata 14 December 1958. The between Amokura and Te Kauwhata remain single track, as does Ngāruawāhia bridge. Doubling of the section south of Amokura is being investigated in a business case from July 2021.

In 1930, the Westfield deviation was opened, creating a new eastern route from Auckland to Westfield via Glen Innes and Hobsons Bay, running into the new Auckland railway station and providing better access to the Port of Auckland. The original section between Auckland and Westfield via Newmarket later ceased to be part of the NIMT: Auckland to Newmarket became the Auckland Newmarket Line, and Newmarket to Westfield became part of the North Auckland Line (NAL) which runs between Whangarei and Westfield. In the late 1930s, bridges replaced level crossings at Ohinewai, Taupiri and Hopuhopu.

The double track Tawa Flat deviation opened to goods trains on 22 July 1935 and to passenger trains on 19 June 1937, bypassing the original single track WMR line between Wellington and Tawa. With a pair of tunnels under the Wellington hills, the deviation alleviated issues with more and heavier freight traffic on the steep and twisting original route where long sections at 1 in 60 gradient required banker engines. The Wellington to Johnsonville section of the original line was retained as the Johnsonville Line and the Johnsonville to Tawa section closed. The sections from Plimmerton to South Junction, north of Pukerua Bay and Muri, and North Junction to Paekākāriki were duplicated in 1940. From 24 July 1940 electrification at 1500 V DC of the southern section of the NIMT from Wellington to Paekākāriki was completed. The Tawa Flat deviation has a long tunnel (Tawa No 2) not suitable for steam operation because of excessive smoke (although steam trains were temporarily operated in the new deviation from 1935). A Centralised Train Control (CTC) system was installed in 1940, so that new signal boxes were not required and five stations between Tawa and Pukerua Bay no longer had to be continually staffed for Tablet operation; see Kapiti Line and North–South Junction. Electrification eliminated the need to relieve the steep (1 in 57) gradients from Plimmerton to the Pukerua Bay summit by a deviation to the east and allowed more frequent suburban passenger trains (and allowed suburban electric multiple units to run on this section from September 1949). The difficult section down the Paekakariki Escarpment from Pukerua Bay to Paekākāriki with five tunnels between South and North Junctions remains single track. Duplication from Tawa to Porirua opened on 15 December 1957, from Porirua to Paremata on 7 November 1960, and Paremata to Plimmerton on 16 October 1961. The section between Porirua and Plimmerton was straightened in conjunction with the duplication by reclaiming land along the eastern shore of Porirua Harbour. In 1967, the floors of the tunnels on the former WMR section between Paekākāriki and Pukerua Bay were lowered to enable the DA class locomotives to travel all the way to Wellington.

Between 1964 and 1966, a deviation away from the centre of Palmerston North via the Milson deviation on the edge of the city.

Between 1973 and 1981, the major Mangaweka deviation in the central section between Mangaweka and Utiku was built, with three viaducts, all over 70m tall, crossing the Rangitīkei and Kawhatau rivers. The viaducts were at the end of their economic lives. The deviation removed a number of tunnels, many of which were built in unstable country, and eliminated a number of steep gradients. A combined road and rail deviation had bean considered with the Ministry of Works, but was too expensive. In 1966 the NZR General Manager Alan Gandell said that the deviation would eliminate five old and narrow tunnels, and that New Zealand topography precluded a fast run, but travel time would be cut from 13½ hours to between 11½ and 12 hours, the best possible without tremendous expense. But two modern express trains were being designed for the NIMT, and should be introduced in three to four years.

The central section from Te Rapa near Hamilton to Palmerston North was electrified between 1984 and 1988 as part of the Think Big government energy program. Some tunnels were opened out or bypassed by deviations while in others clearances were increased, and curves eased. The section between Ohakune and Horopito was realigned with three viaducts replaced to handle higher loads and speeds. The most notable bridge replaced was the curved metal viaduct at Hapuawhenua by a modern concrete structure, though the original has been restored as a tourist attraction.

In 1980 the 1880s Poro O Tarao Tunnel in the King Country was replaced by a tunnel with clearances which allowed for large hicube containers. In 2009–10, the section of line between Wellington Junction and Distant Junction was rebuilt from double track to triple track, to ease peak time congestion. In February 2011, duplication between Paekākāriki and Waikanae was completed as part of the upgrade and expansion of the Wellington suburban network; see Kapiti Line for more information. In 2012–13, four bridges near Rangiriri between Auckland and Hamilton were replaced. The bridges were all over 100 years old with steel spans and timber piers, and were replaced by modern low maintenance concrete ballast deck bridges. Bridges 479, 480, 481 & 482 were replaced, with lengths of , , and respectively. The construction of the Peka Peka to Otaki section of the Kāpiti Expressway required of the NIMT immediately north of Otaki station to be realigned. Construction began in 2017, and trains were switched onto the new alignment over the 2019 Easter long weekend (19–22 April). In the Auckland area, a third main line between Wiri and Westfield (or Papakura) is under construction; this will allow freight (or other) trains to bypass stationary passenger trains.

There are three independent sections of the NIMT which are electrified: Auckland's urban network and the central section (25 kV AC) from Palmerston North – Te Rapa (north of Hamilton) at 25 kV AC. Wellington's urban network is electrified at 1500 V DC; as formerly used in other sections of the New Zealand network. In Wellington the operating voltage has been increased to 1650V DC, and 1700V DC since the full introduction of the Matangi EMU, to increase the power available. Electrification of the NIMT was mooted by electrical engineer Evan Parry in the first volume of the New Zealand Journal of Science and Technology in November 1918. In light of a national coal shortage following World War I, Parry argued that the network was under great strain due to ever increasing volumes of freight, and the use of steam traction was partly to blame. Parry also noted that there was great potential for cheap hydro electricity generation in the central North Island to power electrification. The first part of the NIMT to be electrified was the Wellington–Paekakariki section via the Tawa Flat deviation that was completed on 24 July 1940. This was largely to prevent smoke nuisance in the 4.3 km No. 2 tunnel, and to provide for banking on the Paekakariki to Pukerua Bay section. Electric traction in this section is now used only by Transdev Wellington for Metlink suburban passenger services on the Kapiti Line, and was extended to Paraparaumu on 7 May 1983 and Waikanae on 20 February 2011. Funded by the Greater Wellington Regional Council, the extension to Waikanae coincided with the delivery of new FP class Matangi electric multiple units. Following the Second World War railway services suffered due to skill and coal shortages. Skilled staff sought employment opportunities elsewhere in the economy. From 1948 to 1951 the General Manager of the Railways Department , Frank Aickin advocated electrification of the entire line, despite protests from his engineering staff. Aickin had previously been Staff Superintendent and Chief Legal Advisor to the Department and considered using diesel locomotives for trains on the NIMT to be too expensive. He turned his attention to electrification, mainly because he saw that it could relieve the coal situation and prevent high expenditure on imported fuels. He commissioned a study into electrification, which concluded that a low frequency AC system could be cheaper than 1500 V DC, the system in use in Wellington. Aickin sent a technical mission of four senior officers overseas in March 1949 and travelled overseas himself to negotiate a tentative contract with a British construction company. The Chief Mechanical Engineer and Chief Accountant specified and costed the system and Aickin was able to complete a substantial report justifying the NIMT electrification and submit it to the Government. Officers from New Zealand Treasury and the Ministry of Works and two experts from Sweden (Thelander and Edenius) commented on the proposal and in December 1950 the Government granted approval in principle and agreed to appoint Thelander as a consultant. Aickin later fell out with the then National Government and retired as General Manager in July 1951. With the change in regime, the electrification proposal disappeared. A key assumption of Aickin's report was that traffic on the NIMT would grow by 50% from 1948 to 1961. Since a diesel electric locomotive is a travelling power station, the savings through electrification compared to diesel could be regarded as the difference between the cost of buying bulk electrical energy generated substantially from New Zealand resources and the cost of generating electricity in a small plant using imported diesel fuel. The Royal Commission on Railways created following Aickin's tenure rejected the report's findings. Aickin's successor Horace Lusty, revised the tentative contract with English Electric to specify DF class diesel electric locomotives. They were later found to be unreliable, and only ten were supplied. 42 DG class locomotives were supplied instead for secondary lines. For main lines including the NIMT, the General Motors G12 export models were ordered, becoming the DA class. The section between Palmerston North and Hamilton was electrified at 25 kV 50 Hz AC, opened on 24 June 1988 as one of the Muldoon National Government's "Think Big" energy development projects. An overall cost in excess of $100 million had been projected, with some 40% being for the locomotives, but the final cost was about $250 million. The economics of the project was greatly undermined by the fall of the price of oil in the 1980s and the deregulation of land transport, which removed the long distance monopoly NZR held when the cost benefit report was written. The electrification of the section, which had its genesis in a study group set up in June 1974 to report on measures to be taken to cope with increasing rail traffic volumes, received approval in 1980. This led to a technical study carried out with assistance from the Japanese Railway Technical Research Institute. The report stated that track capacity would be increased by electrification because such traction is faster and able to move more freight at once. The report stated, for example, that whereas a diesel locomotive could haul 720 tonne trains at up the Raurimu Spiral, an electric locomotive could haul 1100/1200 tonne trains at , cutting 3–5 hours off journey times. Less fuel would be needed and employing regenerative braking in electric locomotives lowers the fuel consumption further. Electrification's advantages were reflected in the economic evaluation in the report, which showed a rate of return of 18%. Sensitivity analysis showed that this high rate of return gave the project robustness against lower traffic volumes than expected (the return remained positive even if traffic fell), against significant increases in construction cost, and against lower than expected rises in the diesel fuel price. Part of the project included replacing the copper wire communications system with a new fibre optic communications cable (due to interference caused by AC power with the DC copper wire system) between Wellington and Auckland. In 1994 New Zealand Rail Limited sold the cable to Clear Communications for telephone traffic, leasing part of it back for signalling. Proposals to electrify the Auckland suburban rail network dated back to the 1960s, they mainly coincided with proposals to electrify the NIMT in its entirety. In 2005 the central government decided to implement a proposal to electrify the urban network at 25 kV AC, the same system as on the central NIMT. This included of the NIMT itself, from Britomart to just south of Papakura. Work on electrification of the Auckland network began in 2010. The first revenue electric services using AM class EMUs commenced on 28 April 2014 between Britomart and Onehunga on the Onehunga Line. The electrification project on the Auckland network, including the Auckland Papakura section of the NIMT, was completed in July 2015, with all suburban services being electric. A diesel shuttle service runs on the non electrified Pukekohe Papakura section.

From opening, there have been regular passenger services between Wellington and Auckland. The daily "Express" left earlier in the evening, followed by the "Limited", which had fewer stops for passengers. Between 1963 and 1968, daytime trains were called the Scenic Daylight. In 1968, a Drewery NZR RM class articulated 88 seater railcar was refurbished and repainted in a distinctive blue and white scheme that led to it being nicknamed the Blue Streak. It initially operated an unsuccessful service between Hamilton and Auckland in early 1968, and was transferred to the Auckland Wellington run on 23 September 1968. Note that all self propelled passenger railcar classes in New Zealand are generically classed 'RM'. In 1971, NZR introduced the Silver Star, a luxury sleeper train. The service was not economically viable and was withdrawn in 1979. Much more successful was the Silver Fern, a daytime railcar service, introduced in 1972 to replace the "Blue Streak". This service was withdrawn in 1991 and replaced by The Overlander. In conjunction with the introduction of the carriage train Overlander service, the Silver Fern railcars were redeployed to start new services between Tauranga and Auckland – Kaimai Express, and Auckland and Rotorua – Geyserland Express, in 1991. In 2000 a new commuter service called the Waikato Connection was introduced between Hamilton and Auckland and ran in conjunction with the services to Tauranga and Rotorua until all three services were cancelled in 2001. On 25 July 2006, Toll NZ announced that the Overlander would cease at the end of September 2006, but on 28 September 2006, the train's continuation on a limited timetable was announced. It ran daily during the summer months and thrice weekly for the balance of the year. In 2012, KiwiRail announced the Overlander would be replaced by the Northern Explorer, with modern New Zealand built AK class carriages to provide a premium tourist train on a quicker timetable with fewer stops. It commenced on Monday 25 June 2012, and consisted of one train running from Auckland to Wellington on Mondays, Thursdays and Saturdays, and Wellington to Auckland on Wednesdays, Fridays and Sundays. It had fewer stops than the Overlander, stopping only at Papakura, Hamilton, Ōtorohanga, National Park, Ohakune, Palmerston North and Paraparaumu. The Northern Explorer scheduled passenger service was suspended in December 2021. The service was reinstated from 25 September 2022. In 2021 a new commuter service between Hamilton and Auckland was introduced, named Te Huia. The Capital Connection commuter train operates between Palmerston North and Wellington. Both KiwiRail and private enthusiast operators such as the Railway Enthusiasts Society, Mainline Steam and Steam Incorporated operate charter trains.

Wellington's Metlink suburban network, operated by Transdev Wellington, includes the southern portion of the NIMT between Wellington and Waikanae as the Kapiti Line.
