96-677: In the 1910s, the New Zealand Railways Department intended to build a railway up the Leader River's valley as part of the Main North Line linking Christchurch with the Marlborough region. Between 1912 and 1914, roughly 3 kilometres (2 mi) of track was laid northwards from Parnassus up the Leader River's valley, a few more kilometres of formation was made, and work began on a bridge over

192-434: A decline in passenger, freight and train miles run but also led to an increase in profitability. In the 1917 Annual Report, a record 5.3% return on investment was made. The war did take its toll on railway services, with dining cars being removed from passenger trains in 1917, replaced by less labour-intensive refreshment rooms at railway stations along the way. As a result, the "scramble for pie and tea at Taihape " became

288-404: A mine or quarry. Initially the wagons were guided by human muscle power; subsequently by various mechanical methods. Timber rails wore rapidly: later, flat cast-iron plates were provided to limit the wear. In some localities, the plates were made L-shaped, with the vertical part of the L guiding the wheels; this is generally referred to as a "plateway". Flanged wheels eventually became universal, and

384-503: A new independent line was proposed to open up an unconnected area, the gauge was crucial in determining the allegiance that the line would adopt: if it was broad gauge, it must be friendly to the Great Western railway; if narrow (standard) gauge, it must favour the other companies. The battle to persuade or coerce that choice became very intense, and became referred to as "the gauge wars" . As passenger and freight transport between

480-621: A new railway station and head office in Wellington were approved, along with the electrification of the Johnsonville Line (then still part of the North Island Main Trunk). The Wellington railway station and Tawa flat deviation were both completed in 1937. As part of attempts by NZR to win back passengers from private motor vehicles, the same year the first 56-foot carriages were introduced. Garnet Mackley

576-580: A novelty in the shape of a mixed-gauge goods train was introduced between Truro and Penzance. It was worked by a narrow-gauge engine, and behind the narrow-gauge trucks came a broad-gauge match-truck with wide buffers and sliding shackles, followed by the broad-gauge trucks. Such trains continued to run in West Cornwall until the abolition of the Broad Gauge; they had to stop or come down to walking pace at all stations where fixed points existed and

672-457: A part of New Zealand folklore. Non-essential rail services were curtailed as more staff took part in the war effort, and railway workshops were converted for producing military equipment, on top of their existing maintenance and construction work. The war soon affected the supply of coal to the railways. Although hostilities ended in 1918, the coal shortage carried on into 1919 as first miners strikes and then an influenza epidemic cut supplies. As

768-582: A population of 362 to each mile of railway already made. In August 1881 the Railways Construction and Land Act was passed, allowing joint-stock companies to build and run private railways, as long as they were built to the government's standard rail gauge of 1,067 mm ( 3 ft 6 in ) and connected with the government railway lines. The Act had the effect of authorising the Wellington and Manawatu Railway Company to build

864-497: A report known as the "Fay Raven Report" which gave qualified approval to Coates' programme. The reports only significant change was the proposal of a Cook Strait train ferry service between Wellington and Picton, to link the two systems up. Coates went on to become Prime Minister in 1925, an office he held until 1928 when he was defeated at the general election of that year . While the Westfield and Tawa Flat deviations proceeded,

960-399: A result, non-essential services remained in effect until the end of 1919. Shortages of spare parts and materials led to severe inflation, and repairs on locomotives being deferred. Similar coal-saving timetable cuts occurred at the end of the next war in 1945 and 1946. In 1920 the 3,000-mile (4,800 km) milestone of open railway lines was reached and 15 million passengers were carried by

1152-616: A secondary place altogether, and probably will be torn up, and we shall have motor traffic taking their place .” Section 12 of that Act allowed for government borrowing and Section 19 required local councils to provide half the cost of road improvements. By setting in place a system of subsidy from ratepayers and taxpayers, whilst requiring railways to make a 3¾% profit (at that rate, interest amounted to over 22% of total earnings), Coates ensured his prophecy came true, as railways gradually became uneconomic. He also encouraged publicity for rail travel. The following year, Gordon Coates became

1248-657: A slight variation from the nominal gauge for pragmatic reasons. The gauge is defined in imperial units , metric units or SI units. Imperial units were established in the United Kingdom by the Weights and Measures Act 1824 . The United States customary units for length did not agree with the imperial system until 1959, when one international yard was defined as 0.9144 meters and, as derived units, 1 foot (= 1 ⁄ 3  yd) as 0.3048 meter and 1 inch (= 1 ⁄ 36  yd) as 25.4 mm. The list shows

1344-484: Is also used for the suburban railway systems in South Australia , and Victoria , Australia . The term "medium gauge" had different meanings throughout history, depending on the local dominant gauge in use. In 1840s, the 1,600 mm ( 5 ft 3 in ) Irish gauge was considered a medium gauge compared to Brunel's 7 ft  1 ⁄ 4  in ( 2,140 mm ) broad gauge and

1440-506: Is typically greater for track limited to slower speeds, and tighter for track where higher speeds are expected (as an example, in the US the gauge is allowed to vary between 4 ft 8 in (1,420 mm) to 4 ft 10 in (1,470 mm) for track limited to 10 mph (16 km/h), while 70 mph (110 km/h) track is allowed only 4 ft 8 in (1,420 mm) to 4 ft 9 + 1 ⁄ 2  in (1,460 mm). Given

1536-410: Is undertaken when no other alternative is available. The nominal track gauge is the distance between the inner faces of the rails. In current practice, it is specified at a certain distance below the rail head as the inner faces of the rail head (the gauge faces ) are not necessarily vertical. Some amount of tolerance is necessarily allowed from the nominal gauge to allow for wear, etc.; this tolerance

1632-550: Is used between China and Central Asia, and between Poland and Ukraine, using the SUW 2000 and INTERGAUGE variable axle systems. China and Poland use standard gauge, while Central Asia and Ukraine use 1,520 mm ( 4 ft  11 + 27 ⁄ 32  in ). When individual railway companies have chosen different gauges and have needed to share a route where space on the ground is limited, mixed gauge (or dual gauge) track, in which three (sometimes four) rails are supported in

1728-494: The 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) narrow gauge, which became the modern standard gauge . In modern usage, the term "narrow gauge" generally refers to track spaced significantly narrower than 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ). Narrow gauge is the dominant or second dominant gauge in countries of Southern, Central Africa, East Africa, Southeast Asia, Japan, Taiwan, Philippines, Central America and South America, During

1824-599: The Bratislava – Lviv train, and the Romania/Moldova border on the Chișinău – Bucharest train. A system developed by Talgo and Construcciones y Auxiliar de Ferrocarriles (CAF) of Spain uses variable gauge wheelsets ; at the border between France and Spain, through passenger trains are drawn slowly through an apparatus that alters the gauge of the wheels, which slide laterally on the axles. A similar system

1920-559: The English Electric built DE class , were introduced in 1951. The locomotives gave good service but were not powerful or numerous enough to seriously displace steam traction. In 1954, the New Zealand railway network reached its zenith in terms of distance with 5,600 km (3,500 mi), 60% of it on gradients between 1 in 100 and 1 in 200 and 33% steeper than 1 in 100. The EW class electric locomotives introduced for

2016-721: The Grand Junction Railway and the London and Birmingham Railway forming a huge preponderance of standard gauge . When Bristol promoters planned a line from London, they employed the innovative engineer Isambard Kingdom Brunel . He decided on a wider gauge, to give greater stability, and the Great Western Railway adopted a gauge of 7 ft ( 2,134 mm ), later eased to 7 ft  1 ⁄ 4  in ( 2,140 mm ). This became known as broad gauge . The Great Western Railway (GWR)

2112-657: The Leyland experimental petrol railcar and a fleet of Model T Ford railbuses , the Sentinel-Cammell steam railcar and from 1926 the Clayton steam railcar and successful Edison battery-electric railcar . 10 years later in 1936 the Leyland diesel railbus was introduced, but the first truly successful railcar class to enter service began operating that year, the Wairarapa railcar specially designed to operate over

2208-629: The Liberal Government of Premier Richard Seddon appointed Alfred Cadman as the first Minister of Railways . The Minister appointed a General Manager for the railways, keeping the operation under tight political control. Apart from four periods of government-appointed commissions (1889–1894, 1924–1928, 1931–1936 and 1953–1957), this system remained in place until the department was corporatised in 1982. In 1895, patronage had reached 3.9M passengers per annum and 2.048M tonnes. NZR produced its first New Zealand-built steam locomotive in 1889;

2304-510: The Long Depression , which led to great financial constraint on the department. As a result, the central government passed legislation to allow for the construction of more private railways. A Commission, ordered by Hall, had in 1880 reviewed 85 proposed and partly-constructed railway lines in the colony, and it proposed postponing 21 projects and recommended against proceeding with 29 others. The Commissioners were especially critical of

2400-644: The Lyttelton Line in Christchurch, completed in 1929, at the same voltage and current. This again saw English Electric supply locomotives, the EC class . Gordon Coates , on 24 October 1922, as Minister of Public Works, in introducing his Main Highways Act , said, “ I say the day will come when it will be found that through the use of motor transport certain railways in New Zealand will be relegated to

2496-789: The Rimutaka Incline . This class followed the building of the Red Terror (an inspection car on a Leyland Cub chassis) for the General Manager in 1933. More classes followed over the years, primarily to operate regional services. Following the success of the Wairarapa railcar class, in 1938 the Standard class railcars were introduced. A further improvement to passenger transport came in July that year, with electric services on

2592-523: The South Island , mainly consisting of the 630 km (390 mi) Main South Line from the port of Lyttelton to Bluff. The Railways Department was formed in 1880 during the premiership of Sir John Hall . That year, the private Port Chalmers Railway Company Limited was acquired by the department and new workshops at Addington opened. Ironically, the first few years of NZR were marked by

2688-496: The Transmongolian Railway , Russia and Mongolia use 1,520 mm ( 4 ft  11 + 27 ⁄ 32  in ) while China uses the standard gauge of 1,435 mm. At the border, each carriage is lifted and its bogies are changed . The operation can take several hours for a whole train of many carriages. Other examples include crossings into or out of the former Soviet Union: Ukraine/Slovakia border on

2784-672: The W class built in the Addington Railway Workshops . Along with opening new lines, NZR began acquiring a number of the private railways which had built railway lines around the country. It acquired the Waimea Plains Railway Company in 1886. At the same time, a protracted legal battle began with the New Zealand Midland Railway Company , which was only resolved in 1898. The partially completed Midland line

2880-1166: The Waiau Branch and Waiau Ferry in Canterbury . By the 1920s NZR was noticing a considerable downturn in rail passenger traffic on many lines due to increasing ownership of private cars, and from 1923 it began to co-ordinate rail passenger services with private bus services. The New Zealand Railways Road Services branch was formed to operate bus services. In 1911 tenders for bookstalls were being advertised for 33 main stations - Auckland , Frankton Junction , Rotorua . Paeroa , Taumarunui , Ohakune , Taihape , Marton , Feilding , Palmerston North , Levin , Wellington Thorndon and Lambton , Masterton , Woodville , Dannevirke . Waipukurau . Hastings , Napier , New Plymouth , Stratford , Hāwera , Aramoho , Whanganui , Nelson , Christchurch , Ashburton , Timaru , Oamaru , Dunedin , Milton , Gore , and Invercargill . By 1912, patronage had reached 13.4M passengers per annum (a 242% increase since 1895) and 5.9M tonnes of freight (a 188% increase since 1895). In 1913, damages of £15 were awarded against New Zealand Railways to S. J. Gibbons by

2976-755: The Wairarapa and Wellington. This led to the closure of the Rimutaka Incline and its unique Fell railway system. Because steam locomotives could not be operated through the new tunnel, the Wairarapa Line was the first to be fully "dieselised". Amid many protests, the isolated Nelson Section was closed, although future Nelson Railway Proposals resurfaced from 1957. The RM class "88 seater" or "Fiats" also began entering service from 1955. The railcars were designed to take over provincial inter-city routes but proved to be mechanically unreliable. Despite large orders for diesel-electric locomotives, NZR

3072-540: The Wellington - Auckland express was derailed due to a bridge collapse north of Tangiwai due to a lahar from a volcanic eruption, in what became known as the Tangiwai disaster . The following year NZR introduced the dual-cab D class in 1954, the first main-line diesel-electric locomotives in service. They proved to be unsuccessful in service and the original order of 31 was cancelled, and D class locomotives, also built by English Electric , ordered instead. While

3168-684: The Wellington-Manawatu Line . In 1877 the first American locomotives were purchased; the NZR K class (1877) from Rogers , followed by the NZR T class of 1879 from Baldwin . The most important construction project for NZR at this time was the central section of the North Island Main Trunk . Starting from Te Awamutu on 15 April 1885, the section—including the famous Raurimu Spiral —was not completed for another 23 years. The economy gradually improved and in 1895

3264-403: The spacing between the rails had to be compatible with that of the wagon wheels. As the guidance of the wagons was improved, short strings of wagons could be connected and pulled by teams of horses, and the track could be extended from the immediate vicinity of the mine or quarry, typically to a navigable waterway. The wagons were built to a consistent pattern and the track would be made to suit

3360-476: The "gauge", a metal bar with a precisely positioned lug at each end that track crews use to ensure the actual distance between the rails lies within tolerances of a prescribed standard: on curves, for example, the spacing is wider than normal. Deriving from the name of the bar, the distance between these rails is also referred to as the track gauge. The earliest form of railway was a wooden wagonway, along which single wagons were manhandled, almost always in or from

3456-520: The D class proved more successful than the D class, steam remained the dominant form of traction. This led to the introduction of the D class in 1955, the largest fleet of diesel-electric locomotives NZR ever introduced. The D class, more than any other class, displaced steam locomotives from the North Island . On 3 November of the same year the 8.798 kilometres (5.467 mi) long Rimutaka Tunnel opened, greatly reducing transit times between

3552-454: The GWR, there was an extended period between political intervention in 1846 that prevented major expansion of its 7 ft  1 ⁄ 4  in ( 2,140 mm ) broad gauge and the final gauge conversion to standard gauge in 1892. During this period, many locations practicality required mixed gauge operation, and in station areas the track configuration was extremely complex. This

3648-802: The Government Railways Board. Another Act of Parliament, the Government Railways Amendment Act 1931 was passed. The Railways Board was independent of the Government of the day and answered to the Minister of Finance . During this period the Prime Minister George Forbes was also Minister of Railways, and Minister of Finance was former Minister of Railways Gordon Coates . The Railways Board was chaired by Herbert Harry Sterling,

3744-710: The Johnsonville Line starting with the introduction of the DM/D English Electric Multiple Units . Three new locomotive classes appeared in 1939: the K class , K class and the J class . The K was a further development of the K class, while the J class was primarily for lighter trackage in the South Island. The numerically smaller K class were allocated to the Midland line , where they dominated traffic. This led to

3840-417: The Leader River. However, the outbreak of World War I brought a halt to construction, and when work resumed on building the railway, a more easterly route out of Parnassus was chosen. Nonetheless, a pier from the never-completed Leader River bridge continues to stand in the river. 42°44′S 173°18′E  /  42.733°S 173.300°E  / -42.733; 173.300 This article about

Broad gauge is the dominant gauge in countries in Indian subcontinent, the former Soviet Union ( CIS states, Baltic states, Georgia and Ukraine), Mongolia, Finland (which still uses the original Soviet Gauge of 1524mm), Spain, Portugal, Argentina, Chile and Ireland.

4032-650: The Milson deviation and Rimutaka Tunnel projects remained stalled. The onset of the Great Depression from late 1929 saw these projects scaled back or abandoned. The Westfield deviation was completed in 1930 and the Tawa deviation proceeded at a snail's pace. A number of new lines under construction were casualties, including the Rotorua-Taupo line, approved in July 1928 but abandoned almost a year later due to

4128-581: The Minister of Railways. Coates was an ambitious politician who had an almost "religious zeal" for his portfolio. During the summer of 1923, he spent the entire parliamentary recess inspecting the department's operations. The following year, he put forward a "Programme of Improvements and New Works'". Coates scheme proposed spending £8 million over 8 years. This was later expanded to £10 million over 10 years. The programme included: An independent commission, led by Sir Sam Fay and Sir Vincent Raven produced

4224-723: The North Island and Blenheim in the South Island, as part of the " Rail Air " service. In 1950, Straits Air Freight Express (later known as SAFE Air) took over the contract from the RNZAF. The service was discontinued in the early 1980s. The General Manager of NZR, Frank Aickin , was an advocate for electrifying the entire North Island Main Trunk to alleviate the shortage of coal and the cost of importing diesel fuel; though he also recognised that steam and diesel traction would be required on other lines. NZR's first diesel-electric locomotives,

4320-638: The Supreme Court in a precedent-setting case; for damages to a car that hit a train at a level crossing: see Cliff Road railway station . The outbreak of World War I in 1914 had a significant impact on the Railways Department. That year the A class appeared, and the following year the first A class locomotives were introduced. This class went on to become the most numerous locomotive class in New Zealand history, with several examples surviving into preservation. The war itself led to

4416-436: The Wellington electric system. They were the second class of electric locomotive to be used on this section of electrification. They were the most powerful locomotives on the system till the D class arrived in 1972. Aicken went as far as negotiating a tentative contract for the construction of electrification and locomotives for it, but fell out with the Government in late 1951 and resigned. His successor, H.C. Lusty, terminated

4512-402: The allowed tolerance, it is a common practice to widen the gauge slightly in curves, particularly those of shorter radius (which are inherently slower speed curves). Rolling stock on the network must have running gear ( wheelsets ) that are compatible with the gauge, and therefore the gauge is a key parameter in determining interoperability, but there are many others – see below. In some cases in

4608-553: The coining of the phrase "KB country" to describe the area, made famous by the National Film Unit 's documentary of the same title. As with the first world war, the Second World War had a significant impact on railways. The war created major labour shortages across the economy generally, and while considered "essential industry", railways were no exception. A large number of NZR employees signed up to fight in

4704-685: The colony's existing railways' inability to generate sufficient income to pay the interest on the loans that had funded their construction: The extent to which this fatal mistake has been made may be in some degree realized by a comparison of the relations between railways and population in this and other countries. In Great Britain the amount of population to each mile of railway is 1,961; in the United States, 580; in New South Wales, 1,108; in Victoria, 924; while in New Zealand we have only

4800-459: The completion of the Midland Line in the South Island . The tunnel included the first section of railway electrification in New Zealand and its first electric locomotives, the original E class . The section was electrified at 1,500 V DC, due to the steep grade in the tunnel, and included its own hydro-electric power station. The second section to be electrified by the department was

4896-518: The contract and entered into an agreement with General Motors for the supply of 40 EMD G12 model locomotives, designated by NZR as the D class . The first of these locomotives entered service in September 1955, with all of this initial order running by September 1957. On Christmas Eve 1953, the worst disaster in NZR's history, and one of the worst in New Zealand's history occurred. 151 people died when

4992-561: The convenience in laying it and changing its location over unimproved ground. In restricted spaces such as tunnels, the temporary way might be double track even though the tunnel will ultimately be single track. The Airport Rail Link in Sydney had construction trains of 900 mm ( 2 ft  11 + 7 ⁄ 16  in ) gauge, which were replaced by permanent tracks of 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) gauge. During World War I, trench warfare led to

5088-471: The department. An acute housing shortage following the war led to the creation of Railways Department's Housing Scheme in 1922. The first of the now-iconic railway houses were prefabricated in a factory in Frankton for NZR staff. This scheme was shut down in 1929 as it was considered improper for a government department to compete with private builders. The Otira Tunnel was completed in 1923, heralding

5184-605: The depression. An exception was the Stratford–Okahukura Line , finished in 1933. However, there was criticism that maintenance was being neglected. In the Liberals last year of office in 1912, 140 miles (230 km) of line had been relaid, but that was reduced to 118 in 1913, 104 in 1914, 81 in 1924 and 68 in 1925, during the Reform Government 's years. Once again, growing traffic requirements led to

5280-448: The earliest days of railways, the railway company saw itself as an infrastructure provider only, and independent hauliers provided wagons suited to the gauge. Colloquially the wagons might be referred to as "four-foot gauge wagons", say, if the track had a gauge of four feet. This nominal value does not equate to the flange spacing, as some freedom is allowed for. An infrastructure manager might specify new or replacement track components at

5376-461: The ferry and rolled off at the other side. This led to many benefits for NZR customers. Rail gauge In rail transport , track gauge is the distance between the two rails of a railway track . All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks. The term derives from

5472-609: The first decades of the 19th century; they took various forms, but George Stephenson developed a successful locomotive on the Killingworth Wagonway , where he worked. His designs were successful, and when the Stockton and Darlington Railway was opened in 1825, it used his locomotives, with the same gauge as the Killingworth line , 4 ft 8 in ( 1,422 mm ). The Stockton and Darlington line

5568-503: The following year Parliament passed the Transport Licensing Act 1931 . The Act regulated the carriage of goods and entrenched the monopoly the department had on land transport. It set a minimum distance road transport operators could transport goods at 30 miles (48 km) before they had to be licensed. The Act was repealed in 1982. Alongside these changes, in 1931 the Railways Department was briefly restructured into

5664-548: The former General Manager, and had 10 members from around the country. The Board stopped building on the Dargaville branch , Gisborne line, Main South Line, Nelson Section, Okaihau to Rangiahua line and Westport-Inangahua line . For that it was criticised by Bob Semple , the new Minister of Public Works, in a speech in 1935 and abolished by the First Labour Government in 1936. In 1933 plans for

In many cases narrow-gauge track is used for a temporary way because of

5856-476: The introduction of a new type of locomotive, the ill-fated G class Garratt locomotives in 1928. Three of the locomotives were introduced for operation on the North Island Main Trunk. They were not well suited to New Zealand conditions: they had overly complex valve gear , were too hot for crews manning them and too powerful for the wagons they were hauling. The failure of this class lead to

SECTION 60

#1732791405808

5952-463: The introduction of the K class in 1932. Tough economic conditions and increasing competition from road transport led to calls for regulation of the land transport sector. In 1931 it was claimed half a million tons of freight had been lost to road transport. That year, the department carried 7.2 million passengers per year, down from 14.2 million in 1923. In 1930 a Royal Commission on Railways recommended that land transport should be "co-ordinated" and

6048-429: The metal bar, or gauge, that is used to ensure the distance between the rails is correct. Railways also deploy two other gauges to ensure compliance with a required standard. A loading gauge is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in the corresponding envelope. A structure gauge specifies

6144-647: The most powerful locomotive at the time. Gold rushes led to the construction of the Thames Branch , opening in 1898. In 1906 the Dunedin railway station was completed, architect George Troup . A. L. Beattie became Chief Mechanical Officer in April 1900. Beattie designed the famous A class , the Q class (the first "Pacific" type locomotive in the world), and many other locomotive classes. NZR's first bus operation began on 1 October 1907, between Culverden on

6240-404: The narrow portion side-stepped to right or left. In rare situations, three different gauges may converge on to a rail yard and triple-gauge track is needed to meet the operational needs of the break-of-gauge station – most commonly where there is insufficient space to do otherwise. Construction and operation of triple-gauge track and its signalling, however, involves immense cost and disruption, and

6336-470: The needs of the horses and wagons: the gauge was more critical. The Penydarren Tramroad of 1802 in South Wales, a plateway, spaced these at 4 ft 4 in ( 1,321 mm ) over the outside of the upstands. The Penydarren Tramroad probably carried the first journey by a locomotive, in 1804, and it was successful for the locomotive, but unsuccessful for the track: the plates were not strong enough to carry its weight. A considerable progressive step

6432-422: The network's construction. From 1895 to 1993 there was a responsible Minister, the Minister of Railways . He was often also the Minister of Public Works. Apart from four brief experiments with independent boards, NZR remained under direct ministerial control for most of its history. Originally, New Zealand's railways were constructed by provincial governments and private firms. The largest provincial operation

6528-432: The north-east of Scotland adopted 4 ft  6 + 1 ⁄ 2  in ( 1,384 mm ); the Redruth and Chasewater Railway (1825) in Cornwall chose 4 ft ( 1,219 mm ). The Arbroath and Forfar Railway opened in 1838 with a gauge of 5 ft 6 in ( 1,676 mm ), and the Ulster Railway of 1839 used 6 ft 2 in ( 1,880 mm ). Locomotives were being developed in

6624-477: The outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach. The most common use of the term "track gauge" refers to the transverse distance between the inside surfaces of the two load-bearing rails of a railway track , usually measured at 12.7 millimetres (0.50 inches) to 15.9 millimetres (0.63 inches) below the top of the rail head in order to clear worn corners and allow for rail heads having sloping sides. The term derives from

6720-438: The period known as " the Battle of the gauges ", Stephenson's standard gauge was commonly known as "narrow gauge", while Brunel's railway's 7 ft  1 ⁄ 4  in ( 2,140 mm ) gauge was termed " broad gauge ". Many narrow gauge railways were built in mountainous regions such as Wales , the Rocky Mountains of North America, Central Europe and South America. Industrial railways and mine railways across

6816-416: The same track structure, can be necessary. The most frequent need for such track was at the approaches to city terminals or at break-of-gauge stations. Tracks of multiple gauges involve considerable costs in construction (including signalling work) and complexities in track maintenance, and may require some speed restrictions. They are therefore built only when absolutely necessary. If the difference between

6912-497: The space between the rails of a track is colloquially referred to as the "four-foot", and the space between two tracks the "six-foot", descriptions relating to the respective dimensions. In modern usage the term "standard gauge" refers to 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ). Standard gauge is dominant in a majority of countries, including those in North America, most of western Europe, North Africa,

7008-656: The then ECMT, the Taneatua Branch , was also completed. Centralised Traffic Control (CTC) was installed from Taumaranui to Auckland at the same time. In 1946 the last class of steam locomotives built by NZR was introduced, the J class . Due to coal shortages the K , J , K , J classes of steam locomotives were converted from coal to oil burning. Following the war, NZR contracted the Royal New Zealand Air Force from 1947 to ship inter-island freight across Cook's Strait between Paraparaumu in

7104-553: The two areas became increasingly important, the difficulty of moving from one gauge to the other—the break of gauge —became more prominent and more objectionable. In 1845 a Royal Commission on Railway Gauges was created to look into the growing problem, and this led to the Regulating the Gauge of Railways Act 1846 , which forbade the construction of broad gauge lines unconnected with the broad gauge network. The broad gauge network

7200-617: The two gauges is large enough – for example between 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ) standard gauge and 3 ft 6 in ( 1,067 mm ) – three-rail dual-gauge is possible, but if not – for example between 3 ft 6 in ( 1,067 mm ) and 1,000 mm ( 3 ft  3 + 3 ⁄ 8  in ) metre gauge – four rails must be used. Dual-gauge rail lines occur (or have occurred) in Argentina, Australia, Brazil, Japan, North Korea, Spain, Switzerland, Tunisia and Vietnam. On

7296-525: The various provincial railways. Since the Public Works Department was charged with constructing new railway lines (among other public works) the day to day railway operations were transferred into a new government department on the recommendation of a parliamentary select committee. At the time 1,828 kilometres (1,136 miles) of railway lines were open for traffic, 546 km (339 mi) in the North Island and 1,283 km (797 mi) in

7392-613: The war. For the first time, the Department employed significant numbers of women to meet the shortages. The war created serious coal shortages as imported coal was no longer available. Despite this, NZR had record revenues in 1940. Despite the war and associated labour and material shortages, new railway construction continued. In 1942 the Gisborne Line was finally opened, followed by the Main North Line between Picton and Christchurch being completed in 1945. The final section of

7488-826: The world are often narrow gauge. Sugar cane and banana plantations are mostly served by narrow gauges. Very narrow gauges of under 2 feet (610 mm) were used for some industrial railways in space-restricted environments such as mines or farms. The French company Decauville developed 500 mm ( 19 + 3 ⁄ 4  in ) and 400 mm ( 15 + 3 ⁄ 4  in ) tracks, mainly for mines; Heywood developed 15 in ( 381 mm ) gauge for estate railways . The most common minimum gauges were 15 in ( 381 mm ), 400 mm ( 15 + 3 ⁄ 4  in ), 16 in ( 406 mm ), 18 in ( 457 mm ), 500 mm ( 19 + 3 ⁄ 4  in ) or 20 in ( 508 mm ). Through operation between railway networks with different gauges

7584-443: Was adopted, but many countries or companies chose a different gauge as their national gauge, either by governmental policy, or as a matter of individual choice. Standard gauge is generally known world-wide as being 1,435 mm ( 4 ft  8 + 1 ⁄ 2  in ). Terms such as broad gauge and narrow gauge do not have any fixed meaning beyond being materially wider or narrower than standard. In British practice,

7680-702: Was appointed General Manager in 1933, and worked hard to improve the standard and range of services provided by the Department. This included a number of steps to make passenger trains faster, more efficient and cheaper to run. In the early 20th century, NZR had begun investigating railcar technology to provide passenger services on regional routes and rural branch lines where carriage trains were not economic and "mixed" trains (passenger carriages attached to freight trains) were undesirably slow. However, due to New Zealand's rugged terrain overseas technology could not simply be directly introduced. A number of experimental railcars and railbuses were developed. From 1925 these included

7776-441: Was compounded by the common rail having to be at the platform side in stations; therefore, in many cases, standard-gauge trains needed to be switched from one side of the track to the other at the approach. A special fixed point arrangement was devised for the purpose, where the track layout was simple enough. In some cases, mixed gauge trains were operated with wagons of both gauges. For example, MacDermot wrote: In November 1871

7872-501: Was created in 1880 and was corporatised on 1 April 1982 into the New Zealand Railways Corporation . Originally, railway construction and operation took place under the auspices of the former provincial governments and some private railways, before all of the provincial operations came under the central Public Works Department . The role of operating the rail network was subsequently separated from that of

7968-519: Was eventually converted—a progressive process completed in 1892, called gauge conversion . The same Act mandated the gauge of 5 ft 3 in ( 1,600 mm ) for use in Ireland. As railways were built in other countries, the gauge selection was pragmatic: the track would have to fit the rolling stock. If locomotives were imported from elsewhere, especially in the early days, the track would be built to fit them. In some cases standard gauge

8064-594: Was exempted from the Transport Licensing Act, effectively opening the sector up to competition. The introduction of GMV Aramoana in 1962 heralded the start of inter-island ferry services run by NZR. The service was very successful, leading to criticism, when the Wellington–Lyttelton overnight ferry was withdrawn, that NZR was competing unfairly with private operators. Before the Aramoana

8160-484: Was introduced, NZR could not compete for inter-island freight business, and the rail networks of both the North and South Islands were not well integrated. To send goods between the islands, freight had to be unloaded from wagons onto a ship on one island, unloaded at the other and then loaded back into wagons to resume its journey by rail. The introduction of a roll-on roll-off train ferry changed that. Wagons were rolled onto

8256-445: Was made when cast iron edge rails were first employed; these had the major axis of the rail section configured vertically, giving a much stronger section to resist bending forces, and this was further improved when fish-belly rails were introduced. Edge rails required a close match between rail spacing and the configuration of the wheelsets, and the importance of the gauge was reinforced. Railways were still seen as local concerns: there

8352-566: Was no appreciation of a future connection to other lines, and the choice of track gauge was still a pragmatic decision based on local requirements and prejudices, and probably determined by existing local designs of (road) vehicles. Thus, the Monkland and Kirkintilloch Railway (1826) in the West of Scotland used 4 ft 6 in ( 1,372 mm ); the Dundee and Newtyle Railway (1831) in

8448-401: Was not handed over to NZR until 1900. By that time, 3,200 km (2,000 mi) of railway lines were open for traffic. The acquisition in 1908 of the Wellington and Manawatu Railway Company and its railway line marked the completion of the North Island Main Trunk from Wellington to Auckland. A new locomotive class, the X class , was introduced in 1909 for traffic on the line. The X class was

8544-474: Was opened to service a new pulp and paper mill at its terminus. NZR's first single-purpose log trains, called "express loggers", began to operate on this branch. The Kinleith Branch was shortly followed in 1957 by the 57 kilometres (35 mi) long Murupara Branch , which was opened running through the Bay of Plenty 's Kaingaroa Forest . The branch is the last major branch line to open in New Zealand to date. The line

8640-532: Was originally impossible; goods had to be transshipped and passengers had to change trains. This was obviously a major obstacle to convenient transport, and in Great Britain, led to political intervention. On narrow gauge lines, rollbocks or transporter wagons are used: standard gauge wagons are carried on narrow gauge lines on these special vehicles, generally with rails of the wider gauge to enable those vehicles to roll on and off at transfer points. On

8736-559: Was primarily built to service the Tasman Pulp and Paper Mill in Kawerau , with several loading points along its length. The line's success led to several Taupo Railway Proposals being put forward, with extensions of the branch being mooted at various times. In 1960 the second Christchurch railway station , at Moorhouse Avenue, was opened. The station was closed in 1990, with a new station being built at Addington. In 1961, livestock

8832-497: Was referred to as "narrow gauge" to indicate the contrast. Some smaller concerns selected other non-standard gauges: the Eastern Counties Railway adopted 5 ft ( 1,524 mm ). Most of them converted to standard gauge at an early date, but the GWR's broad gauge continued to grow. The larger railway companies wished to expand geographically, and large areas were considered to be under their control. When

8928-628: Was still building steam locomotives until 1956, when the last steam locomotive built by NZR, J 1274, was completed at Hillside Workshops , Dunedin . The locomotive is now preserved in Dunedin near the railway station. During the 1950s New Zealand industry was diversifying, particularly into the timber industry. On 6 October 1952 the Kinleith Branch , formerly part of the Taupo Totara Timber Company Railway ,

9024-449: Was successful and was greatly expanded, directly and through friendly associated companies, widening the scope of broad gauge. At the same time, other parts of Britain built railways to standard gauge, and British technology was exported to European countries and parts of North America, also using standard gauge. Britain polarised into two areas: those that used broad gauge and those that used standard gauge. In this context, standard gauge

9120-567: Was the Canterbury Provincial Railways , which opened the first public railway at Ferrymead on 1 December 1863. During The Vogel Era of the late 1860s to the 1870s, railway construction by central government expanded greatly, from just 80 kilometres (50 miles) in 1869 to 1,900 kilometres (1,200 miles) in 1880. Following the abolition of the provinces in 1877, the Public Works Department took over

9216-482: Was very successful, and when the Liverpool and Manchester Railway , the first intercity line, was opened in 1830, it used the same gauge. It too was very successful, and the gauge, widened to 4 ft  8 + 1 ⁄ 2  in or 1,435 mm and named " standard gauge ", was well on its way to becoming the established norm. The Liverpool and Manchester was quickly followed by other trunk railways, with
