79-858: The Frankfurt City Tunnel is a standard gauge railway in Frankfurt and the core of the Rhine-Main S-Bahn . The line runs underground for its entire length. The first section was put into operation on 28 May 1978 to Hauptwache . S-Bahn trains began operating on the Taunus Railway (S1), the Main-Lahn Railway (S2), the Limes Railway (S3), the Kronberg Railway (S4), the Homburg Railway (S5) and
158-408: A carbody design that would reduce wind resistance at high speeds. A long series of tests was carried. In 1905, St. Louis Car Company built a railcar for the traction magnate Henry E. Huntington , capable of speeds approaching 160 km/h (100 mph). Once it ran 32 km (20 mi) between Los Angeles and Long Beach in 15 minutes, an average speed of 130 km/h (80 mph). However, it

316-578: A high-speed railway network in Russian gauge . There are no narrow gauge high-speed railways. Countries whose legacy network is entirely or mostly of a different gauge than 1435mm – including Japan and Spain – have however often opted to build their high speed lines to standard gauge instead of the legacy railway gauge. High-speed rail is the fastest and most efficient ground-based method of commercial transportation. However, due to requirements for large track curves, gentle gradients and grade separated track
395-546: A new top speed for a regular service, with a top speed of 160 km/h (99 mph). This train was a streamlined multi-powered unit, albeit diesel, and used Jakobs bogies . Following the success of the Hamburg line, the steam-powered Henschel-Wegmann Train was developed and introduced in June 1936 for service from Berlin to Dresden , with a regular top speed of 160 km/h (99 mph). Incidentally no train service since
474-555: A some other interurban rail cars reached about 145 km/h (90 mph) in commercial traffic. The Red Devils weighed only 22 tons though they could seat 44 passengers. Extensive wind tunnel research – the first in the railway industry – was done before J. G. Brill in 1931 built the Bullet cars for Philadelphia and Western Railroad (P&W). They were capable of running at 148 km/h (92 mph). Some of them were almost 60 years in service. P&W's Norristown High Speed Line
553-510: A standard gauge of 4 ft 8 + 1 ⁄ 2 in ( 1,435 mm ), and those in Ireland to a new standard gauge of 5 ft 3 in ( 1,600 mm ). In Great Britain, Stephenson's gauge was chosen on the grounds that existing lines of this gauge were eight times longer than those of the rival 7 ft or 2,134 mm (later 7 ft 1 ⁄ 4 in or 2,140 mm ) gauge adopted principally by
632-423: A time-consuming and expensive process. The result was the adoption throughout a large part of the world of a "standard gauge" of 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ), allowing interconnectivity and interoperability. A popular legend that has circulated since at least 1937 traces the origin of the 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) gauge even further back than
711-569: A world record for narrow gauge trains at 145 km/h (90 mph), giving the Odakyu engineers confidence they could safely and reliably build even faster trains at standard gauge. Conventional Japanese railways up until that point had largely been built in the 1,067 mm ( 3 ft 6 in ) Cape gauge , however widening the tracks to standard gauge ( 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in )) would make very high-speed rail much simpler due to improved stability of
790-476: Is a set of unique features, not merely a train travelling above a particular speed. Many conventionally hauled trains are able to reach 200 km/h (124 mph) in commercial service but are not considered to be high-speed trains. These include the French SNCF Intercités and German DB IC . The criterion of 200 km/h (124 mph) is selected for several reasons; above this speed,

#1732791436404948-480: Is defined in U.S. customary / Imperial units as exactly "four feet eight and one half inches", which is equivalent to 1,435.1 mm. As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – a " gauge break " – loads had to be unloaded from one set of rail cars and reloaded onto another,
1027-539: Is still in use, almost 110 years after P&W in 1907 opened their double-track Upper Darby–Strafford line without a single grade crossing with roads or other railways. The entire line was governed by an absolute block signal system. On 15 May 1933, the Deutsche Reichsbahn-Gesellschaft company introduced the diesel-powered " Fliegender Hamburger " in regular service between Hamburg and Berlin (286 km or 178 mi), thereby achieving
1106-571: Is the most widely used track gauge around the world, with about 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia , Finland , Uzbekistan , and some line sections in Spain . The distance between the inside edges of the rails is defined to be 1,435 mm except in the United States, Canada, and on some heritage British lines, where it
1185-619: The Chicago-New York Electric Air Line Railroad project to reduce the running time between the two big cities to ten hours by using electric 160 km/h (99 mph) locomotives. After seven years of effort, however, less than 50 km (31 mi) of arrow-straight track was finished. A part of the line is still used as one of the last interurbans in the US. In the US, some of the interurbans (i.e. trams or streetcars which run from city to city) of
1264-553: The 0 Series Shinkansen , built by Kawasaki Heavy Industries – in English often called "Bullet Trains", after the original Japanese name Dangan Ressha ( 弾丸列車 ) – outclassed the earlier fast trains in commercial service. They traversed the 515 km (320 mi) distance in 3 hours 10 minutes, reaching a top speed of 210 km/h (130 mph) and sustaining an average speed of 162.8 km/h (101.2 mph) with stops at Nagoya and Kyoto.

The tunnel bends to the east and after 250 metres (820 ft) it joins Tunnel C of the Frankfurt U-Bahn , which was built together with the City Tunnel under the Freßgass (the pedestrianised streets of Kalbächer Gasse and Große Bockenheimer Straße, named after its eateries) to Hauptwache . In 1983, the city tunnel was extended, largely in a cut and cover tunnel, 600 metres (2,000 ft) to
1422-681: The Aérotrain , a French hovercraft monorail train prototype, reached 200 km/h (120 mph) within days of operation. After the successful introduction of the Japanese Shinkansen in 1964, at 210 km/h (130 mph), the German demonstrations up to 200 km/h (120 mph) in 1965, and the proof-of-concept jet-powered Aérotrain , SNCF ran its fastest trains at 160 km/h (99 mph). In 1966, French Infrastructure Minister Edgard Pisani consulted engineers and gave
1501-608: The Liverpool and Manchester Railway , authorised in 1826 and opened 30 September 1830. The extra half inch was not regarded at first as very significant, and some early trains ran on both gauges daily without compromising safety. The success of this project led to Stephenson and his son Robert being employed to engineer several other larger railway projects. Thus the 4 ft 8 + 1 ⁄ 2 in ( 1,435 mm ) gauge became widespread and dominant in Britain. Robert
1580-538: The Main-Weser Railway (S6) after climbing a ramp under the former postal station in the tunnel and reached the surface about 500 metres (1,600 ft) east of the central station . The Main Railway service (S14, now S8), was introduced shortly later. The line runs northeast for about 700 metres (2,300 ft) from the central station to Taunusanlage station, built on the site of the old city walls near
1659-590: The Marienfelde – Zossen line during 1902 and 1903 (see Experimental three-phase railcar ). On 23 October 1903, the S&;H-equipped railcar achieved a speed of 206.7 km/h (128.4 mph) and on 27 October the AEG-equipped railcar achieved 210.2 km/h (130.6 mph). These trains demonstrated the feasibility of electric high-speed rail; however, regularly scheduled electric high-speed rail travel

#17327914364041738-647: The Morning Hiawatha service, hauled at 160 km/h (99 mph) by steam locomotives. In 1939, the largest railroad of the world, the Pennsylvania Railroad introduced a duplex steam engine Class S1 , which was designed to be capable of hauling 1200 tons passenger trains at 161 km/h (100 mph). The S1 engine was assigned to power the popular all-coach overnight premier train the Trail Blazer between New York and Chicago since
1817-545: The Prussian state railway joined with ten electrical and engineering firms and electrified 72 km (45 mi) of military owned railway between Marienfelde and Zossen . The line used three-phase current at 10 kilovolts and 45 Hz . The Van der Zypen & Charlier company of Deutz, Cologne built two railcars, one fitted with electrical equipment from Siemens-Halske , the second with equipment from Allgemeine Elektrizitäts-Gesellschaft (AEG), that were tested on
1896-729: The Tōkaidō Shinkansen , began operations in Honshu , Japan, in 1964. Due to the streamlined spitzer -shaped nose cone of the trains , the system also became known by its English nickname bullet train . Japan's example was followed by several European countries, initially in Italy with the Direttissima line, followed shortly thereafter by France , Germany , and Spain . Today, much of Europe has an extensive network with numerous international connections. More recent construction since
1975-532: The United Kingdom , the United States , and Uzbekistan . Only in continental Europe and Asia does high-speed rail cross international borders. High-speed trains mostly operate on standard gauge tracks of continuously welded rail on grade-separated rights of way with large radii . However, certain regions with wider legacy railways , including Russia and Uzbekistan, have sought to develop
2054-474: The World Bank , whilst supporting the project, considered the design of the equipment as unproven for that speed, and set the maximum speed to 210 km/h (130 mph). After initial feasibility tests, the plan was fast-tracked and construction of the first section of the line started on 20 April 1959. In 1963, on the new track, test runs hit a top speed of 256 km/h (159 mph). Five years after
2133-573: The 21st century has led to China taking a leading role in high-speed rail. As of 2023 , China's HSR network accounted for over two-thirds of the world's total. In addition to these, many other countries have developed high-speed rail infrastructure to connect major cities, including: Austria , Belgium , Denmark , Finland , Greece , Indonesia , Morocco , the Netherlands , Norway , Poland , Portugal , Russia , Saudi Arabia , Serbia , South Korea , Sweden , Switzerland , Taiwan , Turkey ,
2212-642: The French National Railway started to receive their new powerful CC 7100 electric locomotives, and began to study and evaluate running at higher speeds. In 1954, the CC 7121 hauling a full train achieved a record 243 km/h (151 mph) during a test on standard track. The next year, two specially tuned electric locomotives, the CC 7107 and the prototype BB 9004, broke previous speed records, reaching respectively 320 km/h (200 mph) and 331 km/h (206 mph), again on standard track. For

The classic line Paris– Toulouse was chosen, and fitted, to support 200 km/h (120 mph) rather than 140 km/h (87 mph). Some improvements were set, notably the signals system, development of on board "in-cab" signalling system, and curve revision. The next year, in May 1967, a regular service at 200 km/h (120 mph)
2370-913: The Great Western Railway. It allowed the broad-gauge companies in Great Britain to continue with their tracks and expand their networks within the "Limits of Deviation" and the exceptions defined in the Act. After an intervening period of mixed-gauge operation (tracks were laid with three rails), the Great Western Railway finally completed the conversion of its network to standard gauge in 1892. In North East England, some early lines in colliery ( coal mining ) areas were 4 ft 8 in ( 1,422 mm ), while in Scotland some early lines were 4 ft 6 in ( 1,372 mm ). The British gauges converged starting from 1846 as

The modern method of measuring rail gauge was agreed in the first Berne rail convention of 1886. Several lines were initially built as standard gauge but were later converted to another gauge for cost or for compatibility reasons. 2,295 km (1,426 mi) Victoria built

Above those speeds positive train control or the European Train Control System becomes necessary or legally mandatory. National domestic standards may vary from the international ones. Railways were the first form of rapid land transportation and had an effective monopoly on long-distance passenger traffic until
2686-645: The advantages of equipment interchange became increasingly apparent. By the 1890s, the entire network was converted to standard gauge. The Royal Commission made no comment about small lines narrower than standard gauge (to be called "narrow gauge"), such as the Ffestiniog Railway . Thus it permitted a future multiplicity of narrow gauges in the UK. It also made no comments about future gauges in British colonies, which allowed various gauges to be adopted across
2765-579: The beginning of the construction work, in October 1964, just in time for the Olympic Games , the first modern high-speed rail, the Tōkaidō Shinkansen , was opened between the two cities; a 510 km (320 mi) line between Tokyo and Ōsaka. As a result of its speeds, the Shinkansen earned international publicity and praise, and it was dubbed the "bullet train." The first Shinkansen trains,

In August 2019, the travel time between Dresden-Neustadt and Berlin-Südkreuz was 102 minutes. See Berlin–Dresden railway . Further development allowed the usage of these "Fliegenden Züge" (flying trains) on a rail network across Germany. The "Diesel-Schnelltriebwagen-Netz" (diesel high-speed-vehicle network) had been in

Snopes categorised this legend as "false", but commented that it "is perhaps more fairly labeled as 'Partly true, but for trivial and unremarkable reasons. ' " The historical tendency to place the wheels of horse-drawn vehicles around 5 ft ( 1,524 mm ) apart probably derives from
3081-534: The colonies. Parts of the United States, mainly in the Northeast, adopted the same gauge, because some early trains were purchased from Britain. The American gauges converged, as the advantages of equipment interchange became increasingly apparent. Notably, all the 5 ft ( 1,524 mm ) broad gauge track in the South was converted to "almost standard" gauge 4 ft 9 in ( 1,448 mm ) over
3160-562: The construction of high-speed rail is more costly than conventional rail and therefore does not always present an economical advantage over conventional speed rail. Multiple definitions for high-speed rail are in use worldwide. The European Union Directive 96/48/EC, Annex 1 (see also Trans-European high-speed rail network ) defines high-speed rail in terms of: The International Union of Railways (UIC) identifies three categories of high-speed rail: A third definition of high-speed and very high-speed rail requires simultaneous fulfilment of
3239-459: The course of two days beginning on 31 May 1886. See Track gauge in the United States . In continental Europe, France and Belgium adopted a 1,500 mm ( 4 ft 11 + 1 ⁄ 16 in ) gauge (measured between the midpoints of each rail's profile ) for their early railways. The gauge between the interior edges of the rails (the measurement adopted from 1844) differed slightly between countries, and even between networks within

3318-464: The curve radius should be quadrupled; the same was true for the acceleration and braking distances. In 1891 engineer Károly Zipernowsky proposed a high-speed line from Vienna to Budapest for electric railcars at 250 km/h (160 mph). In 1893 Wellington Adams proposed an air-line from Chicago to St. Louis of 252 miles (406 km), at a speed of only 160 km/h (99 mph). Alexander C. Miller had greater ambitions. In 1906, he launched

JNR engineers returned to Japan with a number of ideas and technologies they would use on their future trains, including alternating current for rail traction, and international standard gauge. In 1957, the engineers at the private Odakyu Electric Railway in Greater Tokyo Area launched the Odakyu 3000 series SE EMU. This EMU set
3476-508: The development of the motor car and airliners in the early-mid 20th century. Speed had always been an important factor for railroads and they constantly tried to achieve higher speeds and decrease journey times. Rail transportation in the late 19th century was not much slower than non-high-speed trains today, and many railroads regularly operated relatively fast express trains which averaged speeds of around 100 km/h (62 mph). High-speed rail development began in Germany in 1899 when

At the South station the S-Bahn connects with regional and main line services was built, trams and the U-Bahn. The second section , which was completed in 1992, branches off to the east on
3634-595: The early 20th century were very high-speed for their time (also Europe had and still does have some interurbans). Several high-speed rail technologies have their origin in the interurban field. In 1903 – 30 years before the conventional railways started to streamline their trains – the officials of the Louisiana Purchase Exposition organised the Electric Railway Test Commission to conduct a series of tests to develop
3713-462: The east beneath the Zeil to Konstablerwache . This section is also a joint tunnel with the U-Bahn; the S-Bahn lines run between the U-Bahn lines. The tunnel has a train frequency of roughly 28 trains per hour in each direction, that is one train every two minutes. During the rush hour the frequency is approximately one train every two minutes. The next major phase of construction followed in 1990 when
3792-620: The entrance for a tunnel branching towards Frankfurt East station was built for the proposed north Main branch of the S-Bahn to Hanau . Standard-gauge railway A standard-gauge railway is a railway with a track gauge of 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ). The standard gauge is also called Stephenson gauge (after George Stephenson ), international gauge , UIC gauge , uniform gauge , normal gauge in Europe, and SGR in East Africa. It
3871-740: The first railways to the 5 ft 3 in ( 1,600 mm ) Irish broad gauge. New South Wales then built to the standard gauge, so trains had to stop on the border and passengers transferred, which was only rectified in the 1960s. Queensland still runs on a narrow gauge but there is a standard gauge line from NSW to Brisbane. NMBS/SNCB 3,619 km (2,249 mi) Brussels Metro 40 km (25 mi) Trams in Brussels 140 km (87 mi) 1,032 km (641 mi) The Toronto Transit Commission uses 4 ft 10 + 7 ⁄ 8 in ( 1,495 mm ) gauge on its streetcar and subway lines. Takoradi to Sekondi Route,
3950-438: The first time, 300 km/h (185 mph) was surpassed, allowing the idea of higher-speed services to be developed and further engineering studies commenced. Especially, during the 1955 records, a dangerous hunting oscillation , the swaying of the bogies which leads to dynamic instability and potential derailment was discovered. This problem was solved by yaw dampers which enabled safe running at high speeds today. Research
4029-575: The following two conditions: The UIC prefers to use "definitions" (plural) because they consider that there is no single standard definition of high-speed rail, nor even standard usage of the terms ("high speed", or "very high speed"). They make use of the European EC Directive 96/48, stating that high speed is a combination of all the elements which constitute the system: infrastructure, rolling stock and operating conditions. The International Union of Railways states that high-speed rail

#17327914364044108-414: The impacts of geometric defects are intensified, track adhesion is decreased, aerodynamic resistance is greatly increased, pressure fluctuations within tunnels cause passenger discomfort, and it becomes difficult for drivers to identify trackside signalling. Standard signaling equipment is often limited to speeds below 200 km/h (124 mph), with the traditional limits of 127 km/h (79 mph) in
4187-429: The initial gauge of 4 ft 8 in ( 1,422 mm ) was set to accommodate the existing gauge of hundreds of horse-drawn chaldron wagons that were already in use on the wagonways in the mines. The railway used this gauge for 15 years before a change was made, debuting around 1850, to the 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) gauge. The historic Mount Washington Cog Railway ,

After decades of research and successful testing on a 43 km (27 mi) test track, in 2014 JR Central began constructing a Maglev Shinkansen line, which is known as the Chūō Shinkansen . These Maglev trains still have the traditional underlying tracks and the cars have wheels. This serves a practical purpose at stations and a safety purpose out on

In 1936, the Twin Cities Zephyr entered service, from Chicago to Minneapolis, with an average speed of 101 km/h (63 mph). Many of these streamliners posted travel times comparable to or even better than their modern Amtrak successors, which are limited to 127 km/h (79 mph) top speed on most of
4424-457: The line was extended in a southeasterly direction. Ostendstraße station was built between the streets of Hanauer Landstrasse and Ostendstraße. 300 metres (980 ft) further south the route crosses the Main . The tunnel was built by digging a trench in the river bottom and sinking the tunnel tubes into it, half the river at a time. After passing under the Main the tunnel divides: One branch runs in

However, in normal operation, the wheels are raised up into the car as the train reaches certain speeds where the magnetic levitation effect takes over. It will link Tokyo and Osaka by 2037, with the section from Tokyo to Nagoya expected to be operational by 2027. Maximum speed is anticipated at 505 km/h (314 mph). The first generation train can be ridden by tourists visiting

It too reached 160 km/h (99 mph) in commercial service, and achieved a world mean speed record of 203 km/h (126 mph) between Florence and Milan in 1938. In Great Britain in the same year, the streamlined steam locomotive Mallard achieved
4661-469: The official world speed record for steam locomotives at 202.58 km/h (125.88 mph). The external combustion engines and boilers on steam locomotives were large, heavy and time and labor-intensive to maintain, and the days of steam for high speed were numbered. In 1945, a Spanish engineer, Alejandro Goicoechea , developed a streamlined, articulated train that was able to run on existing tracks at higher speeds than contemporary passenger trains. This
4740-607: The old 4 ft ( 1,219 mm ) plateway was relaid to 5 ft ( 1,524 mm ) so that Blenkinsop's engine could be used. Others were 4 ft 4 in ( 1,321 mm ) (in Beamish ) or 4 ft 7 + 1 ⁄ 2 in ( 1,410 mm ) (in Bigges Main (in Wallsend ), Kenton , and Coxlodge ). English railway pioneer George Stephenson spent much of his early engineering career working for

On 26 May 1934, one year after Fliegender Hamburger introduction, the Burlington Railroad set an average speed record on long distance with their new streamlined train, the Zephyr , at 124 km/h (77 mph) with peaks at 185 km/h (115 mph). The Zephyr

#17327914364044898-436: The rails is better, thus the minimum distance between the wheels (and, by extension, the inside faces of the rail heads ) was the important one. A standard gauge for horse railways never existed, but rough groupings were used; in the north of England none was less than 4 ft ( 1,219 mm ). Wylam colliery's system, built before 1763, was 5 ft ( 1,524 mm ), as was John Blenkinsop 's Middleton Railway ;
4977-411: The rest of the network. All other railways use 1,668 mm ( 5 ft 5 + 21 ⁄ 32 in ) ( broad gauge ) and/or 1,000 mm ( 3 ft 3 + 3 ⁄ 8 in ) metre gauge . BLS , Rigi Railways (rack railway) 449 km Several states in the United States had laws requiring road vehicles to have a consistent gauge to allow them to follow ruts in
5056-579: The road. Those gauges were similar to railway standard gauge. High-speed rail High-speed rail ( HSR ) is a type of rail transport network utilizing trains that run significantly faster than those of traditional rail, using an integrated system of specialized rolling stock and dedicated tracks . While there is no single standard that applies worldwide, lines built to handle speeds above 250 km/h (155 mph) or upgraded lines in excess of 200 km/h (125 mph) are widely considered to be high-speed. The first high-speed rail system,
5135-429: The term "narrow gauge" for gauges less than standard did not arise for many years, until the first such locomotive-hauled passenger railway, the Ffestiniog Railway , was built. In 1845, in the United Kingdom of Great Britain and Ireland , a Royal Commission on Railway Gauges reported in favour of a standard gauge. The subsequent Gauge Act ruled that new passenger-carrying railways in Great Britain should be built to

5293-540: The wider rail gauge, and thus standard gauge was adopted for high-speed service. With the sole exceptions of Russia, Finland, and Uzbekistan all high-speed rail lines in the world are still standard gauge, even in countries where the preferred gauge for legacy lines is different. The new service, named Shinkansen (meaning new main line ) would provide a new alignment, 25% wider standard gauge utilising continuously welded rails between Tokyo and Osaka with new rolling stock, designed for 250 km/h (160 mph). However,
5372-479: The width needed to fit a carthorse in between the shafts. Research, however, has been undertaken to support the hypothesis that "the origin of the standard gauge of the railway might result from an interval of wheel ruts of prehistoric ancient carriages". In addition, while road-travelling vehicles are typically measured from the outermost portions of the wheel rims, it became apparent that for vehicles travelling on rails, having main wheel flanges that fit inside
5451-426: The world's first mountain -climbing rack railway , is still in operation in the 21st century, and has used the earlier 4 ft 8 in ( 1,422 mm ) gauge since its inauguration in 1868. George Stephenson introduced the 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) gauge (including a belated extra 1 ⁄ 2 in (13 mm) of free movement to reduce binding on curves ) for
5530-629: The world's population, without a single train passenger fatality. (Suicides, passengers falling off the platforms, and industrial accidents have resulted in fatalities.) Since their introduction, Japan's Shinkansen systems have been undergoing constant improvement, not only increasing line speeds. Over a dozen train models have been produced, addressing diverse issues such as tunnel boom noise, vibration, aerodynamic drag , lines with lower patronage ("Mini shinkansen"), earthquake and typhoon safety, braking distance , problems due to snow, and energy consumption (newer trains are twice as energy-efficient as
5609-415: Was achieved by providing the locomotive and cars with a unique axle system that used one axle set per car end, connected by a Y-bar coupler. Amongst other advantages, the centre of mass was only half as high as usual. This system became famous under the name of Talgo ( Tren Articulado Ligero Goicoechea Oriol ), and for half a century was the main Spanish provider of high-speed trains. In the early 1950s,
5688-530: Was also made about "current harnessing" at high-speed by the pantographs, which was solved 20 years later by the Zébulon TGV 's prototype. With some 45 million people living in the densely populated Tokyo– Osaka corridor, congestion on road and rail became a serious problem after World War II , and the Japanese government began thinking about ways to transport people in and between cities. Because Japan
5767-403: Was extended a further 161 km (100 mi), and further construction has resulted in the network expanding to 2,951 km (1,834 mi) of high speed lines as of 2024, with a further 211 km (131 mi) of extensions currently under construction and due to open in 2031. The cumulative patronage on the entire system since 1964 is over 10 billion, the equivalent of approximately 140% of
5846-543: Was made of stainless steel and, like the Fliegender Hamburger, was diesel powered, articulated with Jacobs bogies , and could reach 160 km/h (99 mph) as commercial speed. The new service was inaugurated 11 November 1934, traveling between Kansas City and Lincoln , but at a lower speed than the record, on average speed 74 km/h (46 mph). In 1935, the Milwaukee Road introduced
5925-407: Was not only a part of the Shinkansen revolution: the Shinkansen offered high-speed rail travel to the masses. The first Bullet trains had 12 cars and later versions had up to 16, and double-deck trains further increased the capacity. After three years, more than 100 million passengers had used the trains, and the milestone of the first one billion passengers was reached in 1976. In 1972, the line
6004-605: Was reported to have said that if he had had a second chance to choose a gauge, he would have chosen one wider than 4 ft 8 + 1 ⁄ 2 in ( 1,435 mm ). "I would take a few inches more, but a very few". During the " gauge war " with the Great Western Railway , standard gauge was called " narrow gauge ", in contrast to the Great Western's 7 ft 1 ⁄ 4 in ( 2,140 mm ) broad gauge . The modern use of
6083-525: Was resource limited and did not want to import petroleum for security reasons, energy-efficient high-speed rail was an attractive potential solution. Japanese National Railways (JNR) engineers began to study the development of a high-speed regular mass transit service. In 1955, they were present at the Lille 's Electrotechnology Congress in France, and during a 6-month visit, the head engineer of JNR accompanied
6162-402: Was still more than 30 years away. After the breakthrough of electric railroads, it was clearly the infrastructure – especially the cost of it – which hampered the introduction of high-speed rail. Several disasters happened – derailments, head-on collisions on single-track lines, collisions with road traffic at grade crossings, etc. The physical laws were well-known, i.e. if the speed was doubled,
6241-477: Was too heavy for much of the tracks, so Cincinnati Car Company , J. G. Brill and others pioneered lightweight constructions, use of aluminium alloys, and low-level bogies which could operate smoothly at extremely high speeds on rough interurban tracks. Westinghouse and General Electric designed motors compact enough to be mounted on the bogies. From 1930 on, the Red Devils from Cincinnati Car Company and
