91-569: The Stratford–Okahukura Line (SOL) is a secondary railway line in the North Island of New Zealand , between the Marton - New Plymouth Line (MNPL) and the North Island Main Trunk (NIMT) Railway, with 15 intermediate stations. It is 144 km (89 mi) long through difficult country, with 24 tunnels, 91 bridges and a number of sections of 1 in 50 (2 % ) grade . Near Okahukura there

182-408: A crank on a driving axle. Steam locomotives have been phased out in most parts of the world for economical and safety reasons, although many are preserved in working order by heritage railways . Electric locomotives draw power from a stationary source via an overhead wire or third rail . Some also or instead use a battery . In locomotives that are powered by high-voltage alternating current ,

273-586: A dining car . Some lines also provide over-night services with sleeping cars . Some long-haul trains have been given a specific name . Regional trains are medium distance trains that connect cities with outlying, surrounding areas, or provide a regional service, making more stops and having lower speeds. Commuter trains serve suburbs of urban areas, providing a daily commuting service. Airport rail links provide quick access from city centres to airports . High-speed rail are special inter-city trains that operate at much higher speeds than conventional railways,

364-710: A fourth rail system in 1890 on the City and South London Railway , now part of the London Underground Northern line . This was the first major railway to use electric traction . The world's first deep-level electric railway, it runs from the City of London , under the River Thames , to Stockwell in south London. The first practical AC electric locomotive was designed by Charles Brown , then working for Oerlikon , Zürich. In 1891, Brown had demonstrated long-distance power transmission, using three-phase AC , between

455-527: A funicular railway at the Hohensalzburg Fortress in Austria. The line originally used wooden rails and a hemp haulage rope and was operated by human or animal power, through a treadwheel . The line is still operational, although in updated form and is possibly the oldest operational railway. Wagonways (or tramways ) using wooden rails, hauled by horses, started appearing in the 1550s to facilitate

546-488: A hydro-electric plant at Lauffen am Neckar and Frankfurt am Main West, a distance of 280 km (170 mi). Using experience he had gained while working for Jean Heilmann on steam–electric locomotive designs, Brown observed that three-phase motors had a higher power-to-weight ratio than DC motors and, because of the absence of a commutator , were simpler to manufacture and maintain. However, they were much larger than

637-431: A steam engine that provides adhesion. Coal , petroleum , or wood is burned in a firebox , boiling water in the boiler to create pressurized steam. The steam travels through the smokebox before leaving via the chimney or smoke stack. In the process, it powers a piston that transmits power directly through a connecting rod (US: main rod) and a crankpin (US: wristpin) on the driving wheel (US main driver) or to

728-469: A transformer in the locomotive converts the high-voltage low-current power to low-voltage high current used in the traction motors that power the wheels. Modern locomotives may use three-phase AC induction motors or direct current motors. Under certain conditions, electric locomotives are the most powerful traction. They are also the cheapest to run and provide less noise and no local air pollution. However, they require high capital investments both for

819-508: A $ 40 million project to reopen the line was a priority. Minister of Transport Michael Wood announced the government's 10-year plan for rail investment on 6 May 2021. Some specific plans could include re-opening the Stratford to Okahukura line. Railway Rail transport (also known as train transport ) is a means of transport using wheeled vehicles running in tracks , which usually consist of two parallel steel rails . Rail transport

910-402: A deviation at Stratford in conjunction with the shifting of that station to the southern edge of town (and the current station building being built). Crossing loops were established at Te Wera, Whangamōmona, Tangarakau, and Ōhura. Three stations (Te Wera, Whangamōmona, and Ōhura) had stationmasters. The short loops meant that long trains had to be split to fit into the loop and siding. The SOL

1001-544: A diesel locomotive from the company in 1909. The world's first diesel-powered locomotive was operated in the summer of 1912 on the Winterthur–Romanshorn railway in Switzerland, but was not a commercial success. The locomotive weight was 95 tonnes and the power was 883 kW with a maximum speed of 100 km/h (62 mph). Small numbers of prototype diesel locomotives were produced in a number of countries through

1092-468: A double track plateway, erroneously sometimes cited as world's first public railway, in south London. William Jessop had earlier used a form of all-iron edge rail and flanged wheels successfully for an extension to the Charnwood Forest Canal at Nanpantan , Loughborough, Leicestershire in 1789. In 1790, Jessop and his partner Outram began to manufacture edge rails. Jessop became a partner in

1183-437: A large turning radius in its design. While high-speed rail is most often designed for passenger travel, some high-speed systems also offer freight service. Since 1980, rail transport has changed dramatically, but a number of heritage railways continue to operate as part of living history to preserve and maintain old railway lines for services of tourist trains. A train is a connected series of rail vehicles that move along

1274-488: A larger locomotive named Galvani , exhibited at the Royal Scottish Society of Arts Exhibition in 1841. The seven-ton vehicle had two direct-drive reluctance motors , with fixed electromagnets acting on iron bars attached to a wooden cylinder on each axle, and simple commutators . It hauled a load of six tons at four miles per hour (6 kilometers per hour) for a distance of one and a half miles (2.4 kilometres). It

1365-423: A locomotive. This involves one or more powered vehicles being located at the front of the train, providing sufficient tractive force to haul the weight of the full train. This arrangement remains dominant for freight trains and is often used for passenger trains. A push–pull train has the end passenger car equipped with a driver's cab so that the engine driver can remotely control the locomotive. This allows one of

1456-562: A more economical service, so they replaced the carriage train. They offered a more regular daily service on a quicker timetable but continued the Express ' s pattern of operating at night. The southbound service arrived in New Plymouth at 11:23 pm and departed for Auckland at 2:34 am. There was some speculation that the service was originally intended to only operate between Auckland and Taumarunui and its late running to New Plymouth

1547-477: A number of trains per hour (tph). Passenger trains can usually be into two types of operation, intercity railway and intracity transit. Whereas intercity railway involve higher speeds, longer routes, and lower frequency (usually scheduled), intracity transit involves lower speeds, shorter routes, and higher frequency (especially during peak hours). Intercity trains are long-haul trains that operate with few stops between cities. Trains typically have amenities such as

1638-650: A piece of circular rail track in Bloomsbury , London, the Catch Me Who Can , but never got beyond the experimental stage with railway locomotives, not least because his engines were too heavy for the cast-iron plateway track then in use. The first commercially successful steam locomotive was Matthew Murray 's rack locomotive Salamanca built for the Middleton Railway in Leeds in 1812. This twin-cylinder locomotive

1729-460: A pivotal role in the development and widespread adoption of the steam locomotive. His designs considerably improved on the work of the earlier pioneers. He built the locomotive Blücher , also a successful flanged -wheel adhesion locomotive. In 1825 he built the locomotive Locomotion for the Stockton and Darlington Railway in the northeast of England, which became the first public steam railway in

1820-439: A revival in recent decades due to road congestion and rising fuel prices, as well as governments investing in rail as a means of reducing CO 2 emissions . Smooth, durable road surfaces have been made for wheeled vehicles since prehistoric times. In some cases, they were narrow and in pairs to support only the wheels. That is, they were wagonways or tracks. Some had grooves or flanges or other mechanical means to keep

1911-448: A serious partial derailment of a wagon occurred, damaging some 8 km of line preventing use by trains without repairs. KiwiRail describes the damage as covering 9.5 km (5.9 mi) of track. Following this KiwiRail decided to mothball the 144 km (89 mi) line, with rail freight now being routed through Palmerston North. Ideas for preserving the line emerged, with hopes that customers and investment could be found to return

2002-724: A single lever to control both engine and generator in a coordinated fashion, and was the prototype for all diesel–electric locomotive control systems. In 1914, world's first functional diesel–electric railcars were produced for the Königlich-Sächsische Staatseisenbahnen ( Royal Saxon State Railways ) by Waggonfabrik Rastatt with electric equipment from Brown, Boveri & Cie and diesel engines from Swiss Sulzer AG . They were classified as DET 1 and DET 2 ( de.wiki ). The first regular used diesel–electric locomotives were switcher (shunter) locomotives . General Electric produced several small switching locomotives in

2093-407: A standard. Following SNCF's successful trials, 50 Hz, now also called industrial frequency was adopted as standard for main-lines across the world. Earliest recorded examples of an internal combustion engine for railway use included a prototype designed by William Dent Priestman . Sir William Thomson examined it in 1888 and described it as a "Priestman oil engine mounted upon a truck which

2184-620: A terminus about one-half mile (800 m) away. A funicular railway was also made at Broseley in Shropshire some time before 1604. This carried coal for James Clifford from his mines down to the River Severn to be loaded onto barges and carried to riverside towns. The Wollaton Wagonway , completed in 1604 by Huntingdon Beaumont , has sometimes erroneously been cited as the earliest British railway. It ran from Strelley to Wollaton near Nottingham . The Middleton Railway in Leeds , which

2275-408: A wheel. This was a large stationary engine , powering cotton mills and a variety of machinery; the state of boiler technology necessitated the use of low-pressure steam acting upon a vacuum in the cylinder, which required a separate condenser and an air pump . Nevertheless, as the construction of boilers improved, Watt investigated the use of high-pressure steam acting directly upon a piston, raising

2366-465: Is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in the United Kingdom at the beginning of the 19th century. The first passenger railway,

2457-410: Is a single, self-powered car, and may be electrically propelled or powered by a diesel engine . Multiple units have a driver's cab at each end of the unit, and were developed following the ability to build electric motors and other engines small enough to fit under the coach. There are only a few freight multiple units, most of which are high-speed post trains. Steam locomotives are locomotives with

2548-538: Is an unusual combined road-rail bridge over the Ongarue River, with the one-lane road carriageway below the single rail track. The line is not currently in service for rail traffic and is under a 30-year lease for a tourist venture. In July 2019 KiwiRail's CEO stated that reopening the line was a priority. Minister of Transport Michael Wood announced the government's 10-year plan for rail investment on 6 May 2021, which specifically stated that plans could include re-opening

2639-399: Is dominant. Electro-diesel locomotives are built to run as diesel–electric on unelectrified sections and as electric locomotives on electrified sections. Alternative methods of motive power include magnetic levitation , horse-drawn, cable , gravity, pneumatics and gas turbine . A passenger train stops at stations where passengers may embark and disembark. The oversight of the train is

2730-477: Is one of the two primary means of land transport , next to road transport . It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed . Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains . Power is usually provided by diesel or electrical locomotives . While railway transport

2821-543: Is seven miles to the south of the junction in Okahukura; accordingly, a connecting train ran between Taumarunui and Okahukura. In 1940, the independent service began operating thrice weekly year-round. It departed Auckland at 7:50   pm on Sundays, Tuesdays, and Thursdays, made refreshment stops in Frankton and Taumarunui as NZR did not operate dining cars at this point in history, and arrived in New Plymouth at 7:19 am

2912-550: Is worked on a temporary line of rails to show the adaptation of a petroleum engine for locomotive purposes." In 1894, a 20 hp (15 kW) two axle machine built by Priestman Brothers was used on the Hull Docks . In 1906, Rudolf Diesel , Adolf Klose and the steam and diesel engine manufacturer Gebrüder Sulzer founded Diesel-Sulzer-Klose GmbH to manufacture diesel-powered locomotives. Sulzer had been manufacturing diesel engines since 1898. The Prussian State Railways ordered

3003-527: The Stockton and Darlington Railway , opened in 1825. The quick spread of railways throughout Europe and North America, following the 1830 opening of the first intercity connection in England, was a key component of the Industrial Revolution . The adoption of rail transport lowered shipping costs compared to water transport, leading to "national markets" in which prices varied less from city to city. In

3094-609: The United Kingdom , South Korea , Scandinavia, Belgium and the Netherlands. The construction of many of these lines has resulted in the dramatic decline of short-haul flights and automotive traffic between connected cities, such as the London–Paris–Brussels corridor, Madrid–Barcelona, Milan–Rome–Naples, as well as many other major lines. High-speed trains normally operate on standard gauge tracks of continuously welded rail on grade-separated right-of-way that incorporates

3185-414: The overhead lines and the supporting infrastructure, as well as the generating station that is needed to produce electricity. Accordingly, electric traction is used on urban systems, lines with high traffic and for high-speed rail. Diesel locomotives use a diesel engine as the prime mover . The energy transmission may be either diesel–electric , diesel-mechanical or diesel–hydraulic but diesel–electric

3276-458: The puddling process in 1784. In 1783 Cort also patented the rolling process , which was 15 times faster at consolidating and shaping iron than hammering. These processes greatly lowered the cost of producing iron and rails. The next important development in iron production was hot blast developed by James Beaumont Neilson (patented 1828), which considerably reduced the amount of coke (fuel) or charcoal needed to produce pig iron. Wrought iron

3367-418: The rotary phase converter , enabling electric locomotives to use three-phase motors whilst supplied via a single overhead wire, carrying the simple industrial frequency (50 Hz) single phase AC of the high-voltage national networks. An important contribution to the wider adoption of AC traction came from SNCF of France after World War II. The company conducted trials at AC 50 Hz, and established it as

3458-532: The 1880s, railway electrification began with tramways and rapid transit systems. Starting in the 1940s, steam locomotives were replaced by diesel locomotives . The first high-speed railway system was introduced in Japan in 1964, and high-speed rail lines now connect many cities in Europe , East Asia , and the eastern United States . Following some decline due to competition from cars and airplanes, rail transport has had

3549-510: The 1930s (the famous " 44-tonner " switcher was introduced in 1940) Westinghouse Electric and Baldwin collaborated to build switching locomotives starting in 1929. In 1929, the Canadian National Railways became the first North American railway to use diesels in mainline service with two units, 9000 and 9001, from Westinghouse. Although steam and diesel services reaching speeds up to 200 km/h (120 mph) were started before

3640-500: The 1960s in Europe, they were not very successful. The first electrified high-speed rail Tōkaidō Shinkansen was introduced in 1964 between Tokyo and Osaka in Japan. Since then high-speed rail transport, functioning at speeds up to and above 300 km/h (190 mph), has been built in Japan, Spain, France , Germany, Italy, the People's Republic of China, Taiwan (Republic of China),

3731-460: The 40 km Burgdorf–Thun line , Switzerland. Italian railways were the first in the world to introduce electric traction for the entire length of a main line rather than a short section. The 106 km Valtellina line was opened on 4 September 1902, designed by Kandó and a team from the Ganz works. The electrical system was three-phase at 3 kV 15 Hz. In 1918, Kandó invented and developed

Stratford–Okahukura Line - Misplaced Pages Continue

3822-568: The Auckland-New Plymouth express trains from 1956, but were cut back to New Plymouth-Taumarunui in 1971. Mixed trains were withdrawn in 1975. Scheduled passenger trains ceased in January 1983 as roads in the rugged and isolated northern Taranaki were improved and passengers switched to cars, though the line was not closed to all passenger trains until January 2007, after an excursion to Whangamōmona 's "Republic Day" celebrations. This terminated

3913-522: The Butterley Company in 1790. The first public edgeway (thus also first public railway) built was Lake Lock Rail Road in 1796. Although the primary purpose of the line was to carry coal, it also carried passengers. These two systems of constructing iron railways, the "L" plate-rail and the smooth edge-rail, continued to exist side by side until well into the early 19th century. The flanged wheel and edge-rail eventually proved its superiority and became

4004-511: The DC motors of the time and could not be mounted in underfloor bogies : they could only be carried within locomotive bodies. In 1894, Hungarian engineer Kálmán Kandó developed a new type 3-phase asynchronous electric drive motors and generators for electric locomotives. Kandó's early 1894 designs were first applied in a short three-phase AC tramway in Évian-les-Bains (France), which was constructed between 1896 and 1898. In 1896, Oerlikon installed

4095-719: The Marton - New Plymouth Line the SOL also provided an alternative route when the North Island Main Trunk was closed between Marton and Taumarunui. In 1953 the Tangiwai disaster closed the NIMT for a period. The SOL suffered from a lack of investment and maintenance, leading to a number of speed restrictions being put in place. In July 2002 a fatal derailment occurred at Te Wera, and a number of other incidents also plagued operations. In November 2009

4186-631: The Night Limited, as it was to continue to Wellington , and ran as a separate train to New Plymouth, departing Taumarunui at 12:45 am and arriving in New Plymouth just after 6 am. The return working left New Plymouth at 7:10 pm, connected with the Night Limited in Taumarunui, and was conveyed back to Auckland by the Limited for a 7:10 am arrival. Joint running with the Night Limited for

4277-582: The Public Works Minister, K J Williams , officially opened the line from Okahukura. The Mayor of Stratford celebrated the piercing of the last tunnel (52.5 chains or 3,460 ft or 1,060 m No.4 Mangatiti) on 2 August 1932 and, on 7 November 1932, the last spike was driven at Heao by the Prime Minister, the Right Hon. George Forbes , with Rt. Hon. Gordon Coates driving the first train. He said

4368-629: The Stratford to Okahukura line. The line from Stratford to Whangamōmona (of about 48 miles or 77 km) was authorised by the Railways Authorisation Act, 1900 The Hon William Hall-Jones turned the first sod of the Stratford-Okahukura Railway at Stratford on 28 March 1901. Okahukura, south of Ongarue, was to be the junction point with the North Island Main Trunk Line. Construction took nearly 32 years, and

4459-702: The Tauramunui-Auckland leg was the pattern for the 1930s, with the service provided thrice weekly on Mondays, Wednesdays, and Fridays. A class steam locomotives were typical motive power at this stage, and a train from Hāwera connected with the Express in Stratford . At holiday times, the New Plymouth Night Express was run separately from the Night Limited due to large volumes of passengers, and as this service ran directly between New Plymouth and Auckland, it did not pass through Taumarunui, which

4550-450: The completion of automatic single-line signalling on the line. The final section was from Whangamōmona to Okahukura, in those days a distance of 51 miles 52 chains (83.1 km) and consistent with modern distance measurements. Upgrades and maintenance to the track were undertaken in 1959–60. Some of the track was replaced with 75 lbs/yd rail that at some point was made into a continuously welded rail. This work also involved

4641-430: The duty of a guard/train manager/conductor . Passenger trains are part of public transport and often make up the stem of the service, with buses feeding to stations. Passenger trains provide long-distance intercity travel, daily commuter trips, or local urban transit services, operating with a diversity of vehicles, operating speeds, right-of-way requirements, and service frequency. Service frequencies are often expressed as

4732-402: The end of the 19th century, because they were cleaner compared to steam-driven trams which caused smoke in city streets. In 1784 James Watt , a Scottish inventor and mechanical engineer, patented a design for a steam locomotive . Watt had improved the steam engine of Thomas Newcomen , hitherto used to pump water out of mines, and developed a reciprocating engine in 1769 capable of powering

4823-467: The end of the 19th century, improving the quality of steel and further reducing costs. Thus steel completely replaced the use of iron in rails, becoming standard for all railways. The first passenger horsecar or tram , Swansea and Mumbles Railway , was opened between Swansea and Mumbles in Wales in 1807. Horses remained the preferable mode for tram transport even after the arrival of steam engines until

4914-515: The engine by one power stroke. The transmission system employed a large flywheel to even out the action of the piston rod. On 21 February 1804, the world's first steam-powered railway journey took place when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren ironworks, near Merthyr Tydfil in South Wales . Trevithick later demonstrated a locomotive operating upon

5005-470: The era of great expansion of railways that began in the late 1860s. Steel rails lasted several times longer than iron. Steel rails made heavier locomotives possible, allowing for longer trains and improving the productivity of railroads. The Bessemer process introduced nitrogen into the steel, which caused the steel to become brittle with age. The open hearth furnace began to replace the Bessemer process near

5096-609: The final and stronger structures. At the opening ceremony, the Minister for Public Works, the Hon Gordon Coates (subsequently Prime Minister, 1925-1928) said the cost of building that segment of the line was £33,000 per mile. At the same time, a separate report indicates that the track had been laid from Stratford for 47 miles (76 km) up to Tahora, leaving a 31-mile (50 km) gap between Tahora and Matiere. Ōhura had passenger and goods trains run by PWD from 18 December 1926, when

5187-515: The first commercial example of the system on the Lugano Tramway . Each 30-tonne locomotive had two 110 kW (150 hp) motors run by three-phase 750 V 40 Hz fed from double overhead lines. Three-phase motors run at a constant speed and provide regenerative braking , and are well suited to steeply graded routes, and the first main-line three-phase locomotives were supplied by Brown (by then in partnership with Walter Boveri ) in 1899 on

5278-568: The highest possible radius. All these features are dramatically different from freight operations, thus justifying exclusive high-speed rail lines if it is economically feasible. New Plymouth Night Express In 1933, the Stratford–Okahukura Line was completed, providing a rail link through northern Taranaki between the Marton - New Plymouth Line and the North Island Main Trunk Railway . On 4 September 1933,

5369-1218: The limit being regarded at 200 to 350 kilometres per hour (120 to 220 mph). High-speed trains are used mostly for long-haul service and most systems are in Western Europe and East Asia. Magnetic levitation trains such as the Shanghai maglev train use under-riding magnets which attract themselves upward towards the underside of a guideway and this line has achieved somewhat higher peak speeds in day-to-day operation than conventional high-speed railways, although only over short distances. Due to their heightened speeds, route alignments for high-speed rail tend to have broader curves than conventional railways, but may have steeper grades that are more easily climbed by trains with large kinetic energy. High kinetic energy translates to higher horsepower-to-ton ratios (e.g. 20 horsepower per short ton or 16 kilowatts per tonne); this allows trains to accelerate and maintain higher speeds and negotiate steep grades as momentum builds up and recovered in downgrades (reducing cut and fill and tunnelling requirements). Since lateral forces act on curves, curvatures are designed with

5460-646: The line had cost £2.9m and had 265,000 sleepers. Goods traffic started on 12 December 1932, though the SOL was not handed over by the Public Works Department to the New Zealand Railways Department until 3 September 1933. The line was unsignalled and worked under "open section working" when two trains collided at the northern portal to the Whangamomona Tunnel on 21 December 1934; Train No 521

5551-516: The line in emergencies and to resume control of the line depending on future circumstances and opportunities. The rail bridge over State Highway 4 at Okahukura has been removed making the track between the easternmost tunnel and Okahukura unusable. In 2019 the Rail & Maritime Transport Union revealed that a review of the line is being undertaken to assess the viability of reopening for "Fonterra and log traffic." In July KiwiRail CEO Greg Miller stated that

Adventure tourism operator Forgotten World Adventures reached an agreement with KiwiRail in 2012 to lease the line for their new venture using modified petrol rail carts for tourists to travel between the line's termini at Stratford and Okahukura, via a number of trip options, starting from Labour Weekend 2012. The 30-year lease makes the company responsible for the line's maintenance and access control but allows KiwiRail to use

5733-851: The local population and allowed mixed trains to cease to operate along the route from 1 December 1975. The 88 seater railcars were mechanically deteriorating by this stage and last operated on 11 February 1978, but unlike most other provincial railcar services, the New Plymouth-Taumarunui run was not outright cancelled. There was sufficient traffic to justify a replacement carriage train, and its consist initially comprised carriages made from de-motorised 88 seater railcars; these carriages were known as Grassgrubs in New Zealand railfan jargon due to their paint scheme. The railcars were not designed to be hauled as carriages and were soon replaced by ordinary passenger carriages. Around this time, roads through

5824-429: The locomotive-hauled train's drawbacks to be removed, since the locomotive need not be moved to the front of the train each time the train changes direction. A railroad car is a vehicle used for the haulage of either passengers or freight. A multiple unit has powered wheels throughout the whole train. These are used for rapid transit and tram systems, as well as many both short- and long-haul passenger trains. A railcar

5915-560: The main portion of the B&;O to the new line to New York through a series of tunnels around the edges of Baltimore's downtown. Electricity quickly became the power supply of choice for subways, abetted by the Sprague's invention of multiple-unit train control in 1897. By the early 1900s most street railways were electrified. The London Underground , the world's oldest underground railway, opened in 1863, and it began operating electric services using

6006-433: The mid-1920s. The Soviet Union operated three experimental units of different designs since late 1925, though only one of them (the E el-2 ) proved technically viable. A significant breakthrough occurred in 1914, when Hermann Lemp , a General Electric electrical engineer, developed and patented a reliable direct current electrical control system (subsequent improvements were also patented by Lemp). Lemp's design used

6097-484: The new line's ownership was handed over to NZR from the New Zealand Ministry of Works , and early that morning, the first passenger service was operated. This inaugural service left Auckland at 7   pm on 3 September 1933 attached to the Night Limited , and it consisted of one first class carriage, one second class carriage, a sleeping car , and a guard's van. In Taumarunui, these carriages were detached from

6188-467: The next morning. The opposite working left New Plymouth at 7:08   pm on Mondays, Wednesdays, and Fridays, made the same refreshment stops, and arrived in Auckland at 6:30 am the next morning. Operating through to Taumarunui removed the need for a connecting train between Taumarunui and Okahukura, but it did mean the front of the train at the start of the journey became the back for the second leg and

6279-412: The noise they made on the tracks. There are many references to their use in central Europe in the 16th century. Such a transport system was later used by German miners at Caldbeck , Cumbria , England, perhaps from the 1560s. A wagonway was built at Prescot , near Liverpool , sometime around 1600, possibly as early as 1594. Owned by Philip Layton, the line carried coal from a pit near Prescot Hall to

6370-543: The operation of excursions, but efforts were made to have the line upgraded to a standard where excursions will again be possible. A working party of stakeholders was formed in June 2007 to investigate the current state of the line and to develop a case for upgrading it. Considerable maintenance was required to bring the line up to safety standards required for passenger trains at a cost of approximately NZ$ 6 million to complete, according to Stratford Mayor Brian Jeffares.

6461-513: The possibility of a smaller engine that might be used to power a vehicle. Following his patent, Watt's employee William Murdoch produced a working model of a self-propelled steam carriage in that year. The first full-scale working railway steam locomotive was built in the United Kingdom in 1804 by Richard Trevithick , a British engineer born in Cornwall . This used high-pressure steam to drive

6552-536: The seats were reversed. Sleeping car facilities were removed in 1944 due to restrictions caused by World War II , and by 1950, the train ran only twice weekly due to coal shortages. At this stage, J class locomotives had become the primary motive power and the train typically comprised two first class carriages, three second class carriages, and a guard's van. The actual New Plymouth Night Express ceased to operate in 1956. RM class 88 seater railcars had recently been introduced to New Zealand and they provided

6643-441: The standard for railways. Cast iron used in rails proved unsatisfactory because it was brittle and broke under heavy loads. The wrought iron invented by John Birkinshaw in 1820 replaced cast iron. Wrought iron, usually simply referred to as "iron", was a ductile material that could undergo considerable deformation before breaking, making it more suitable for iron rails. But iron was expensive to produce until Henry Cort patented

6734-470: The time, was Liverpool and Manchester Railway , built in 1830. Steam power continued to be the dominant power system in railways around the world for more than a century. The first known electric locomotive was built in 1837 by chemist Robert Davidson of Aberdeen in Scotland, and it was powered by galvanic cells (batteries). Thus it was also the earliest battery-electric locomotive. Davidson later built

6825-536: The track. Propulsion for the train is provided by a separate locomotive or from individual motors in self-propelled multiple units. Most trains carry a revenue load, although non-revenue cars exist for the railway's own use, such as for maintenance-of-way purposes. The engine driver (engineer in North America) controls the locomotive or other power cars, although people movers and some rapid transits are under automatic control. Traditionally, trains are pulled using

6916-466: The transport of ore tubs to and from mines and soon became popular in Europe. Such an operation was illustrated in Germany in 1556 by Georgius Agricola in his work De re metallica . This line used "Hund" carts with unflanged wheels running on wooden planks and a vertical pin on the truck fitting into the gap between the planks to keep it going the right way. The miners called the wagons Hunde ("dogs") from

7007-621: The western part, from Stratford, was operated as the Toko Branch from 9 August 1902. The SOL was nearly complete before the onset of the Great Depression , so work was not halted, unlike on many public works projects such as the East Coast Main Trunk Railway beyond Taneatua . The section from Okahukura to Matiere was officially opened on Tuesday 23 May 1922, although the bridges to the west of Tuhua were temporary rather than

7098-609: The wheels on track. For example, evidence indicates that a 6 to 8.5 km long Diolkos paved trackway transported boats across the Isthmus of Corinth in Greece from around 600 BC. The Diolkos was in use for over 650 years, until at least the 1st century AD. Paved trackways were also later built in Roman Egypt . In 1515, Cardinal Matthäus Lang wrote a description of the Reisszug ,

7189-601: The world in 1825, although it used both horse power and steam power on different runs. In 1829, he built the locomotive Rocket , which entered in and won the Rainhill Trials . This success led to Stephenson establishing his company as the pre-eminent builder of steam locomotives for railways in Great Britain and Ireland, the United States, and much of Europe. The first public railway which used only steam locomotives, all

7280-475: Was a result of this run being extended, but as it turned out, this section of the run was cancelled in 1971 and the railcars operated solely between New Plymouth and Taumarunui. Soon after this change, the service was altered to a daytime run in December 1973, with a departure from New Plymouth at 8:30 am and the return service leaving Taumarunui at 3:10 pm. The new daytime service proved more popular with

7371-507: Was a soft material that contained slag or dross . The softness and dross tended to make iron rails distort and delaminate and they lasted less than 10 years. Sometimes they lasted as little as one year under high traffic. All these developments in the production of iron eventually led to the replacement of composite wood/iron rails with superior all-iron rails. The introduction of the Bessemer process , enabling steel to be made inexpensively, led to

7462-585: Was accomplished by the distribution of weight between a number of wheels. Puffing Billy is now on display in the Science Museum in London, and is the oldest locomotive in existence. In 1814, George Stephenson , inspired by the early locomotives of Trevithick, Murray and Hedley, persuaded the manager of the Killingworth colliery where he worked to allow him to build a steam-powered machine. Stephenson played

7553-509: Was built by Siemens. The tram ran on 180 volts DC, which was supplied by running rails. In 1891 the track was equipped with an overhead wire and the line was extended to Berlin-Lichterfelde West station . The Volk's Electric Railway opened in 1883 in Brighton , England. The railway is still operational, thus making it the oldest operational electric railway in the world. Also in 1883, Mödling and Hinterbrühl Tram opened near Vienna in Austria. It

7644-687: Was built in 1758, later became the world's oldest operational railway (other than funiculars), albeit now in an upgraded form. In 1764, the first railway in the Americas was built in Lewiston, New York . In the late 1760s, the Coalbrookdale Company began to fix plates of cast iron to the upper surface of the wooden rails. This allowed a variation of gauge to be used. At first only balloon loops could be used for turning, but later, movable points were taken into use that allowed for switching. A system

7735-432: Was due to cross with No 556 at Pohokura but departed without the guard as the engine crew claimed they saw his arm horizontal at the rear of the train indicating the train was to proceed; the crews were fortunate that they did not collide in the tunnel. Although generally understood to have trains operating, especially in the later years, on a warrant control basis, mention is made in the 1939 Railways Report to Parliament of

7826-412: Was for the rural hinterland, but along the SOL there were coal mines near Ōhura and Tangarakau, and also sawmills. One freight train operated each weeknight each way along the line carrying freight between New Plymouth and Auckland , interchanging at Taumarunui. In the late 1990s and early 2000s deferred maintenance issues meant these services operated under heavy speed restrictions. In conjunction with

7917-656: Was initially served by the New Plymouth Night Express between New Plymouth and Auckland and by Stratford– Taumarunui passenger trains. When the line opened, it was reported that overnight express trains between Auckland and New Plymouth could now complete the journey in less than 12 hours. On Sundays, Tuesdays and Thursdays trains left Auckland at 7pm, Taumarunui at 12.45am and reached New Plymouth at 6.1am. The trains returned on Mondays, Wednesdays and Fridays, leaving New Plymouth at 7.10pm, Stratford 8.31pm and arriving at Auckland at 7.6am. Whangamōmona had refreshment rooms from 1933 to 1965. Fiat or "88 seater" railcars replaced

8008-535: Was introduced in which unflanged wheels ran on L-shaped metal plates, which came to be known as plateways . John Curr , a Sheffield colliery manager, invented this flanged rail in 1787, though the exact date of this is disputed. The plate rail was taken up by Benjamin Outram for wagonways serving his canals, manufacturing them at his Butterley ironworks . In 1803, William Jessop opened the Surrey Iron Railway ,

8099-479: Was light enough to not break the edge-rails track and solved the problem of adhesion by a cog-wheel using teeth cast on the side of one of the rails. Thus it was also the first rack railway . This was followed in 1813 by the locomotive Puffing Billy built by Christopher Blackett and William Hedley for the Wylam Colliery Railway, the first successful locomotive running by adhesion only. This

8190-742: Was tested on the Edinburgh and Glasgow Railway in September of the following year, but the limited power from batteries prevented its general use. It was destroyed by railway workers, who saw it as a threat to their job security. By the middle of the nineteenth century most european countries had military uses for railways. Werner von Siemens demonstrated an electric railway in 1879 in Berlin. The world's first electric tram line, Gross-Lichterfelde Tramway , opened in Lichterfelde near Berlin , Germany, in 1881. It

8281-609: Was the first tram line in the world in regular service powered from an overhead line. Five years later, in the U.S. electric trolleys were pioneered in 1888 on the Richmond Union Passenger Railway , using equipment designed by Frank J. Sprague . The first use of electrification on a main line was on a four-mile section of the Baltimore Belt Line of the Baltimore and Ohio Railroad (B&O) in 1895 connecting
