The Japanese National Railways ( 日本国有鉄道 , Nihon Kokuyū Tetsudō or Nippon Kokuyū Tetsudō ) abbreviated JNR or Kokutetsu ( 国鉄 ) , was the business entity that operated Japan's national railway network from 1949 to 1987.
47-467: As of June 1, 1949, the date of establishment of JNR, it operated 19,756.8 km (12,276.3 mi) of narrow gauge ( 1,067 mm ( 3 ft 6 in )) railways in all 46 prefectures of Japan. This figure expanded to 21,421.1 km (13,310.5 mi) in 1981 (excluding Shinkansen), but later reduced to 19,633.6 km (12,199.8 mi) as of March 31, 1987, the last day of JNR. JNR operated both passenger and freight services. Shinkansen ,
94-698: A 3 ft 6 in ( 1,067 mm ) gauge, whereas Vietnam, Malaysia and Thailand have metre-gauge railways . Narrow-gauge trams, particularly metre-gauge, are common in Europe. Non-industrial, narrow-gauge mountain railways are (or were) common in the Rocky Mountains of the United States and the Pacific Cordillera of Canada, Mexico, Switzerland, Bulgaria, the former Yugoslavia , Greece, and Costa Rica. A narrow-gauge railway
141-425: A curve with standard-gauge rail ( 1435 mm ) can allow speed up to 145 km/h (90 mph), the same curve with narrow-gauge rail ( 1067mm ) can only allow speed up to 130 km/h (81 mph). In Japan and Queensland, recent permanent-way improvements have allowed trains on 3 ft 6 in ( 1,067 mm ) gauge tracks to exceed 160 km/h (99 mph). Queensland Rail 's Electric Tilt Train ,
188-455: A design speed of 137 km/h (85 mph). Curve radius is also important for high speeds: narrow-gauge railways allow sharper curves, but these limit a vehicle's safe speed. Many narrow gauges, from 15 in ( 381 mm ) gauge to 4 ft 8 in ( 1,422 mm ) gauge, are in present or former use. They fall into several broad categories: 4 ft 6 in ( 1,372 mm ) track gauge (also known as Scotch gauge)
235-481: A difficult problem for JNR. Since public workers were prohibited to strike , they carried out "work-to-rule protests" that caused trains to be delayed. On March 13, 1973, train delays caused by such protests resulted in a riot of angered passengers at Ageo Station in Saitama Prefecture. From November 26, 1975, to December 3, 1975, major labor unions of JNR conducted an eight-day-long illegal "strike for
282-716: A directive of the U.S. General HQ in Tokyo , JGR was reorganized into Japanese National Railways, a state-owned public corporation . JNR enjoyed many successes, including the inauguration of high-speed Shinkansen service along the Tōkaidō Shinkansen line on October 1, 1964. However, JNR was not a state-run corporation; its accounting was independent from the national budget. Rural sections without enough passengers began to press its management, pulling it further and further into debt. In 1983, JNR started to close its unprofitable 83 local lines (the closure continued three years after
329-474: A heavy-duty narrow-gauge line is Brazil's EFVM . 1,000 mm ( 3 ft 3 + 3 ⁄ 8 in ) gauge, it has over-100-pound rail (100 lb/yd or 49.6 kg/m) and a loading gauge almost as large as US non-excess-height lines. The line has a number of 4,000-horsepower (3,000 kW) locomotives and 200-plus-car trains. Narrow gauge's reduced stability means that its trains cannot run at speeds as high as on broader gauges. For example, if
376-503: A mine in Bohemia with a railway of about 2 ft ( 610 mm ) gauge. During the 16th century, railways were primarily restricted to hand-pushed, narrow-gauge lines in mines throughout Europe. In the 17th century, mine railways were extended to provide transportation above ground. These lines were industrial , connecting mines with nearby transportation points (usually canals or other waterways). These railways were usually built to
423-825: A number of large 3 ft ( 914 mm ) railroad systems in North America; notable examples include the Denver & Rio Grande and Rio Grande Southern in Colorado; the Texas and St. Louis Railway in Texas, Arkansas and Missouri; and, the South Pacific Coast , White Pass and Yukon Route and West Side Lumber Co of California. 3 ft was also a common track gauge in South America, Ireland and on
470-519: A public corporation, JNR experienced a series of mysterious incidents as follows. Although the police at that time treated them as terrorism by the communists , doubts have been raised as to the validity of this conclusion. In later years, JNR was a target of radical leftists . On October 21, 1968, groups of extremist students celebrating "International Antiwar Day" occupied and vandalized Shinjuku Station in Tokyo. They criticized JNR's collaboration in
517-699: A range of industrial railways running on 500 mm ( 19 + 3 ⁄ 4 in ) and 400 mm ( 15 + 3 ⁄ 4 in ) tracks, most commonly in restricted environments such as underground mine railways, parks and farms, in France. Several 18 in ( 457 mm ) gauge railways were built in Britain to serve ammunition depots and other military facilities, particularly during World War I . JNR Settlement Corporation The Japanese National Railway Settlement Corporation ( 日本国有鉄道清算事業団 , Nihon Kokuyū Tetsudō Seisan Jigyōdan ) , or JNRSC ,

#1732786714686564-491: Is a track gauge of 1,000 mm ( 3 ft 3 + 3 ⁄ 8 in ). It has about 95,000 km (59,000 mi) of track. According to Italian law, track gauges in Italy were defined from the centre of each rail rather than the inside edges of the rails. This gauge, measured 950 mm ( 3 ft 1 + 3 ⁄ 8 in ) between the edges of the rails, is known as Italian metre gauge . There were
611-488: Is one where the distance between the inside edges of the rails is less than 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ). Historically, the term was sometimes used to refer to what are now standard-gauge railways , to distinguish them from broad-gauge railways , but this use no longer applies. The earliest recorded railway appears in Georgius Agricola 's 1556 De re metallica , which shows
658-1021: The Isle of Man . 900 mm was a common gauge in Europe. Swedish three-foot-gauge railways ( 891 mm or 2 ft 11 + 3 ⁄ 32 in ) are unique to that country and were once common all over the country. Today the only 891 mm line that remains apart from heritage railways is Roslagsbanan , a commuter line that connects Stockholm to its northeastern suburbs. A few railways and tramways were built to 2 ft 9 in ( 838 mm ) gauge, including Nankai Main Line (later converted to 3 ft 6 in or 1,067 mm ), Ocean Pier Railway at Atlantic City , Seaton Tramway ( converted from 2 ft ) and Waiorongomai Tramway . 800 mm ( 2 ft 7 + 1 ⁄ 2 in ) gauge railways are commonly used for rack railways . Imperial 2 ft 6 in ( 762 mm ) gauge railways were generally constructed in
705-641: The Japan Freight Railway Company (JR Freight). In 1987, when the privatization of Japanese National Railways took place, JNR debt totaled over ¥37 trillion. Upon passage of the 1987 Railway Reform Law, the debt of JNR was split, with 60% of the responsibility falling directly on the JNR Settlement Corporation, and 40% falling on three of the JR Group railway companies, JR East , JR Central , and JR West . While
752-530: The Japan Railway Construction, Transport and Technology Agency , the successor body to the JNR Settlement Corporation. The agency said it would pay 20 billion yen, approximately 22 million yen per worker, to 904 plaintiffs. However, as the workers were not reinstated, it was not a full settlement. Between 1950 and 1965, JNR indirectly owned a professional baseball team named Kokutetsu Swallows ( 国鉄スワローズ , Kokutetsu Suwarōzu ) . Swallow
799-689: The Railway Nationalization Act of 1906 and placed under the control of the Railway Institute. Later, the Ministry of Railways and the Ministry of Transportation and Communications took over control of the network. The ministries used the name Japanese Government Railways (JGR) to refer their network in English. During World War II , many JGR lines were dismantled to supply steel for the war effort. On June 1, 1949, by
846-544: The Supreme Court of Japan ruled in favor of the JR Group companies, saying that unfair labor practices by JNR were not the responsibility of the JR Group companies, and as independently operating agencies, they were not legally obligated to hire back the dismissed workers. Litigation on the matter after 1998 rests on the Japan Railway Construction, Transport and Technology Agency, which now holds
893-472: The Vietnam War by operating freight trains carrying jet fuel for U.S. military use. On November 29, 1985, militants supporting a radical sect of JNR's labor union objecting to the privatization of JNR damaged signal cables at 33 points around Tokyo and Osaka to halt thousands of commuter trains and then set fire to Asakusabashi Station in Tokyo. As such, relationships with labor unions were always

Another early use of internal combustion was to power a narrow-gauge locomotive was in 1902. F. C. Blake built a 7 hp petrol locomotive for the Richmond Main Sewerage Board sewage plant at Mortlake . This 2 ft 9 in ( 838 mm ) gauge locomotive
987-515: The JNR Settlement Corporation, later stated that their help in finding work consisted of giving him photocopies of recruitment ads from newspapers. This period ended in April 1990, and 1,047 were dismissed. This included 64 Zendoro members and 966 Kokuro members. Twenty-three years after the original privatization, on June 28, 2010, the Supreme Court settled the dispute between the workers and

#17327867146861034-709: The JNRSC. The goal of disbanding the JNR was to privatize the newly created JR satellite companies, known collectively as the JR Group . Each of the seven companies was created as a kabushiki gaisha with the Japanese government as sole shareholder. Currently, JR East , JR West , JR Central and JR Kyushu are entirely privatized. JNRSC still holds titles to the remaining three JR Group companies, Hokkaido Railway Company (JR Hokkaido), Shikoku Railway Company (JR Shikoku), and
1081-528: The JR companies. There was substantial pressure on union members to leave their unions, and within a year, the membership of the National Railway Workers' Union (Kokuro) fell from 200,000 to 44,000. Workers who had supported the privatization, or those who left Kokuro, were hired at substantially higher rates than Kokuro members. There was a government pledge that no one would be "thrown out onto
1128-584: The Miyajima Ferry remains active as of 2023. A number of unions represented workers at JNR, including the National Railway Workers' Union (Kokuro), the National Railway Locomotive Engineers' Union (Doro), and Doro-Chiba, a break-away group from Doro. The term Kokuyū Tetsudō "state-owned railway" originally referred to a network of railway lines operated by 17 private companies that were nationalized following
1175-952: The Philippines demonstrate that if track is built to a heavy-duty standard, performance almost as good as a standard-gauge line is possible. Two-hundred-car trains operate on the Sishen–Saldanha railway line in South Africa, and high-speed Tilt Trains run in Queensland. In South Africa and New Zealand, the loading gauge is similar to the restricted British loading gauge; in New Zealand, some British Rail Mark 2 carriages have been rebuilt with new bogies for use by Tranz Scenic (Wellington-Palmerston North service), Tranz Metro (Wellington-Masterton service), and Auckland One Rail (Auckland suburban services). Another example of
1222-920: The coal industry. Some sugar cane lines in Cuba were 2 ft 3 + 1 ⁄ 2 in ( 699 mm ). 2 ft ( 610 mm ) gauge railways were generally constructed in the former British colonies. The U.S. had a number of railways of that gauge , including several in the state of Maine such as the Wiscasset, Waterville and Farmington Railway . 1 ft 11 + 3 ⁄ 4 in ( 603 mm ), 600 mm ( 1 ft 11 + 5 ⁄ 8 in ) and 1 ft 11 + 1 ⁄ 2 in ( 597 mm ) were used in Europe. Gauges below 1 ft 11 + 1 ⁄ 2 in ( 597 mm ) were rare. Arthur Percival Heywood developed 15 in ( 381 mm ) gauge estate railways in Britain and Decauville produced
1269-418: The debt has risen to ¥30 trillion ($ 491 billion in 2021 dollars). Many lawsuits and labor commission cases were filed over the decades from the privatization in 1987. Kokuro and the National Railway Locomotive Engineers' Union (Zendoro), both prominent Japanese railway unions, represented a number of the JNR workers. Lists of workers to be employed by the new organizations were drawn up by JNR and given to
1316-544: The fastest train in Australia and the fastest 3 ft 6 in ( 1,067 mm ) gauge train in the world, set a record of 210 km/h (130 mph). The speed record for 3 ft 6 in ( 1,067 mm ) narrow-gauge rail is 245 km/h (152 mph), set in South Africa in 1978. A special 2 ft ( 610 mm ) gauge railcar was built for the Otavi Mining and Railway Company with
1363-575: The former British colonies . 760 mm Bosnian gauge and 750 mm railways are predominantly found in Russia and Eastern Europe. Gauges such as 2 ft 3 in ( 686 mm ), 2 ft 4 in ( 711 mm ) and 2 ft 4 + 1 ⁄ 2 in ( 724 mm ) were used in parts of the UK, particularly for railways in Wales and the borders, with some industrial use in
1410-416: The majority sum of the JNRSC's liability and assets. On June 28, 2010, 23 years after the original privatization, the Supreme Court settled the dispute between the workers and the Japan Railway Construction, Transport and Technology Agency , the successor body to the JNR Settlement Corporation. The agency said it would pay 20 billion yen, approximately 22 million yen per worker, to 904 plaintiffs. However, as
1457-588: The privatization). By 1987, JNR's debt was over ¥27 trillion ($ 442 billion at 2021 exchange rates) and the company was spending ¥147 for every ¥100 earned. Prime Minister Yasuhiro Nakasone , an avowed advocate of privatization , strongly supported breaking up JNR and in August 1982 launched the JNR Reform Commission to officially begin the process. By an act of the Diet of Japan , on April 1, 1987, JNR

1504-998: The right to strike", which resulted in a total defeat of the unions. Narrow gauge A narrow-gauge railway ( narrow-gauge railroad in the US) is a railway with a track gauge narrower than 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) standard gauge . Most narrow-gauge railways are between 600 mm ( 1 ft 11 + 5 ⁄ 8 in ) and 1,067 mm ( 3 ft 6 in ). Since narrow-gauge railways are usually built with tighter curves , smaller structure gauges , and lighter rails ; they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where
1551-550: The same narrow gauge as the mine railways from which they developed. The world's first steam locomotive , built in 1802 by Richard Trevithick for the Coalbrookdale Company, ran on a 3 ft ( 914 mm ) plateway . The first commercially successful steam locomotive was Matthew Murray 's Salamanca built in 1812 for the 4 ft 1 in ( 1,245 mm ) Middleton Railway in Leeds . Salamanca
1598-434: The smaller portion was expected to be repaid, the three JR Group railway companies were not held liable for failed earnings, and only made significant profit through sale of stock. JNR dignitaries staggered interest payments on the large existing debt to keep the JNRSC from paying back the debts that it was expected to. During its tenure, the debt increased, leaving taxpayers to pay off nearly ¥24 trillion as of 2009. When JNR

Around 7,600 workers were transferred in this way, and around 2,000 of them were hired by JR firms, and 3,000 found work elsewhere. Mitomu Yamaguchi, a former JNR employee from Tosu in Saga prefecture who had been transferred to
1692-475: The traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge . In some countries, narrow gauge is the standard: Japan, Indonesia, Taiwan, New Zealand, South Africa, and the Australian states of Queensland , Western Australia and Tasmania have
1739-434: The union or face being laid off. After the restructuring, some 7,600 former JNR workers, mostly Kokuro members, were left without jobs. JNRSC, after acquiring many of them, proceeded to fire more than 1,000. This controversy was cited as example of unfair labor practice by a number of union commissions, and litigation was brought up to fight against the anti-labor acts of JNR and its JR Group successors. On December 22, 2003,
1786-518: The world's first high-speed railway was debuted by JNR in 1964. By the end of JNR in 1987, four lines had been constructed: JNR operated bus lines as feeders, supplements or substitutions of railways. Unlike railway operation, JNR Bus was not superior to other local bus operators. The JR Bus companies are the successors of the bus operation of JNR. JNR operated ferries to connect railway networks separated by sea or to meet other local demands: Out of three routes assigned to JR companies in 1987, only
1833-565: The world; 19th-century mountain logging operations often used narrow-gauge railways to transport logs from mill to market. Significant sugarcane railways still operate in Cuba, Fiji, Java, the Philippines, and Queensland, and narrow-gauge railway equipment remains in common use for building tunnels. In 1897, a manganese mine in the Lahn valley in Germany was using two benzine -fueled locomotives with single cylinder internal combustion engines on
1880-598: Was privatized and divided into seven railway companies, six passenger and one freight, collectively called the Japan Railways Group or JR Group. Long-term liabilities of JNR were taken over by the Japanese National Railway Settlement Corporation . That corporation was subsequently disbanded on October 22, 1998, and its remaining debts were transferred to the national budget's general accounting. By this time
1927-822: Was a symbol of JNR as it is the English equivalent of the Japanese Tsubame , the name of a deluxe train operated by JNR in the 1950s. JNR sold the team to the Sankei Shinbun in 1965, and called the Atoms from 1966 to 1973; the team is now the Tokyo Yakult Swallows and has been owned by the Yakult company since 1970. JNR as a public corporation (from 1949 to 1987) experienced five major accidents (including two shipwrecks of railway ferries) with casualties more than 100: In its very early days as

1974-527: Was a temporary holding company created to distribute the assets of the former Japanese National Railways (JNR) after its privatization in the mid-1980s. On October 22, 1998, the JNRSC was disbanded and placed under the Japan Railway Construction Public Corporation , JRCC, and its assets were transferred. Currently, the Japan Railway Construction, Transport and Technology Agency holds the liabilities and assets of
2021-525: Was adopted by early 19th-century railways, primarily in the Lanarkshire area of Scotland. 4 ft 6 + 1 ⁄ 2 in ( 1,384 mm ) lines were also constructed, and both were eventually converted to standard gauge. 1,067 mm ( 3 ft 6 in ) between the inside of the rail heads, its name and classification vary worldwide and it has about 112,000 kilometres (70,000 mi) of track. As its name implies, metre gauge
2068-563: Was also the first rack-and-pinion locomotive. During the 1820s and 1830s, a number of industrial narrow-gauge railways in the United Kingdom used steam locomotives. In 1842, the first narrow-gauge steam locomotive outside the UK was built for the 1,100 mm ( 3 ft 7 + 5 ⁄ 16 in )-gauge Antwerp-Ghent Railway in Belgium. The first use of steam locomotives on a public, passenger-carrying narrow-gauge railway
2115-517: Was disbanded, many workers were left without jobs. The National Railway Workers' Union (Kokuro), and Japan Railway Motive Power Union , both prominent Japanese railway unions, represented a number of the JNR workers. JNR-provided lists contained workers' names for hire at the seven JR Group railway companies. Members of Kokuro and the Japan Railway Motive Power Union were left off this list after being instructed to leave
2162-560: Was in 1865, when the Ffestiniog Railway introduced passenger service after receiving its first locomotives two years earlier. Many narrow-gauge railways were part of industrial enterprises and served primarily as industrial railways , rather than general carriers. Common uses for these industrial narrow-gauge railways included mining, logging, construction, tunnelling, quarrying, and conveying agricultural products. Extensive narrow-gauge networks were constructed in many parts of
2209-592: Was probably the third petrol-engined locomotive built. Extensive narrow-gauge rail systems served the front-line trenches of both sides in World War I . They were a short-lived military application, and after the war the surplus equipment created a small boom in European narrow-gauge railway building. The heavy-duty 3 ft 6 in ( 1,067 mm ) narrow-gauge railways in Australia (Queensland), New Zealand, South Africa, Japan, Taiwan, Indonesia and
