High-speed rail in China

The high-speed rail network in the People's Republic of China is almost entirely owned and operated by the China State Railway Group Co. under the brand China Railway High-speed, including HSR trains, tracks, and services. China's high-speed rail network is the world's longest and has the highest ridership, as it accounts for roughly two-thirds of the world's total and has expanded to more than 50,000 km in operational length. The HSR network encompasses newly built rail lines with a design speed of.
Since the mid-2000s, China's high-speed rail network has experienced rapid growth. CRH was introduced in April 2007, with the Beijing-Tianjin intercity rail, which became fully operational in August 2008, being the first passenger-dedicated HSR line. Currently, the HSR extends to all provincial-level administrative divisions and the Hong Kong SAR with the exception of Macau SAR.
Due to rapid expansion, China's HSR system has an accumulated debt of $839 billion in 2023.

Technology

Definition and terminology

In China, high-speed rail refers to rail services operating at speeds exceeding. The system generally consists of passenger-dedicated lines with a design speed of, which form the backbone of the national network; regional lines with a design speed of, providing fast interprovincial connections; and intercity lines with a design speed of, serving metropolitan areas with more frequent stops for regional service.
Electric multiple unit trainsets typically consist of 8 or 16 cars and are designed for frequent service with relatively light axle loads. EMU services running below or on mixed-traffic lines are not classified as high-speed rail unless the line is specifically intended for future speed upgrades.
In practice, high-speed rail services in China are divided into three categories:

G-series trains are the fastest and most common, operating at speeds up to about on dedicated high-speed lines. Example: the G7 service between Beijing South and Shanghai Hongqiao, running at 350 km/h.
D-series trains usually run at. They were once common on major daytime routes but have largely been replaced by G-trains. Some are overnight sleeper services, such as the three daily D-trains between Beijing and Shanghai.
C-series trains serve short intercity routes, typically. Example: services on the Beijing–Tianjin Intercity Railway reach 350 km/h and complete the trip in approximately 30 minutes.

Technology transfer

Acquiring high-speed rail technology had been a major goal of Chinese state planners. Chinese train-makers, after receiving transferred foreign technology, have been able to achieve a degree of self-sufficiency in making the next generation of high-speed trains by producing key parts and improving upon foreign designs.
Examples of technology transfer include Mitsubishi Electric's MT205 traction motor and ATM9 transformer to CSR Times Electric Co., Ltd.|CSR Zhuzhou Electric], Hitachi's YJ92A traction motor and Alstom's YJ87A Traction motor to CNR Corporation#Manufacturing and subsidairies|CNR Yongji Electric], Siemens' TSG series pantograph to Zhuzhou Gofront Electric.
For foreign train manufacturers, technology transfer was a crucial part of gaining market access in China. Bombardier, the first foreign train manufacturer to form a joint venture in China, has been sharing technology for the manufacture of railway passenger cars and rolling stock since 1998. Zhang Jianwei, President of Bombardier China, stated that in a 2009 interview, "Whatever technology Bombardier has, whatever the Chinese market needs, there is no need to ask. Bombardier transfers advanced and mature technology to China, which we do not treat as an experimental market." Unlike other series, which have imported prototypes, all CRH1 trains have been assembled at Bombardier's joint venture with CSR, Bombardier Sifang in Qingdao.
Kawasaki's cooperation with CSR did not last as long. Within two years of cooperation with Kawasaki to produce 60 CRH2A sets, CSR began in 2008 to build CRH2B, CRH2C, and CRH2E models at its Sifang plant independently without assistance from Kawasaki. According to CSR president Zhang Chenghong, CSR "made the bold move of forming a systemic development platform for high-speed locomotives and further upgrading its design and manufacturing technology. Later, we began to independently develop high-speed CRH trains with a maximum velocity of 300–350 kilometers per hour, which eventually rolled off the production line in December 2007." Since then, CSR has ended its cooperation with Kawasaki. Kawasaki challenged China's high-speed rail project for patent theft, but backed off the effort.

Rolling stock

China Railway High-speed runs different electric multiple unit trainsets, the name Hexie Hao is for designs which are imported from other nations and designated CRH-1 through CRH-5 and CRH380A, CRH380B, and CRH380C. CRH trainsets are intended to provide fast and convenient travel between cities. Some of the Hexie Hao train sets are manufactured locally through technology transfer, a key requirement for China. The signalling, track and support structures, control software, and station design are developed domestically with foreign elements as well. By 2010, the truck system as a whole is predominantly Chinese. China currently holds several new patents related to the internal components of these trains, redesigned in China to allow the trains to run at higher speeds than the foreign designs allowed. However, these patents are only valid within China, and as such hold no international power. The weakness on intellectual property of Hexie Hao causes obstruction for China to export its high-speed rail related product, which leads to the development of the completely redesigned train franchise called Fuxing Hao that is based on indigenous technologies.

Maglev

The world's first commercial maglev line, capable of speeds up to 430 km/h, opened in Shanghai in 2002 using German technology, linking Longyang Road station with Shanghai Pudong International Airport. On October 19, 2010, the Ministry of Railways announced the beginning of research and development of "super-speed" railway technology, aiming to increase maximum train speeds to over.
In October 2016, CRRC announced research and development of a maglev train, the CRRC 600, and the construction of a test track. In June 2020, a prototype trial run was conducted at Tongji University, with a planned launch targeted for 2025.
In July 2021, China's first high-speed maglev train with a designed top speed of 600 km/h rolled off the production line in Qingdao, Shandong. Developed by CRRC Qingdao Sifang, the train underwent testing on dedicated maglev tracks to prepare for commercial operation.
On 17 July 2025, CRRC officially unveiled the 600 km/h high-speed maglev train at the 12th UIC World Congress on High-Speed Rail in Beijing. The train is designed to bridge the gap between conventional high-speed rail and air travel. Using electromagnetic suspension, the maglev operates without wheel–rail contact, allowing for quieter, smoother, and more efficient service. According to CRRC, the train offers advantages including high speed, safety, reliability, large passenger capacity, lower maintenance costs, and environmental sustainability. The train is expected to enter commercial service within five to ten years and could significantly reduce travel times; for example, the Beijing–Shanghai journey could be shortened from around five hours to about two and a half hours.

Track technology

China's high-speed rail network relies heavily on advanced track technology to allow trains to operate safely at high speeds. A key innovation is the widespread use of ballastless tracks, which replace the traditional gravel base with a solid concrete slab. These tracks provide a smoother ride, reduce long-term maintenance costs, and can handle frequent, heavy train traffic.
Over the years, China has developed several types of ballastless track within the Chinese Railway Track System, including prefabricated slabs that simplify construction and allow precise standardization. Track designs are optimized for different speeds, train loads, and environmental conditions such as temperature variations and uneven subgrade settlement. Advanced design methods, such as the limit state method, are increasingly used to improve safety and material efficiency compared with older allowable stress method approaches.
Currently, four main types of ballastless track are used in China's high-speed rail network: CRTS I, CRTS II, CRTS III slab, and CRTS double-block. CRTS I, CRTS II slab, and CRTS double-block track types were developed by Chinese railway companies based on technology transferred from Germany and Japan. CRTS III slab track is a Chinese innovation, improving upon previous designs and adapted for domestic conditions.

Technology export

China has increasingly promoted the export of its high-speed rail technology, with the most significant achievement to date in Indonesia. In October 2023, the Whoosh line between Jakarta and Bandung opened as the first operational high-speed railway in Southeast Asia. Built by China Railway Construction Corporation and operated by a joint venture with Indonesian partners, the project is considered the first complete export of China's HSR system, including design, construction, rolling stock, and operations.
China has also participated in projects elsewhere. In Turkey, the China Railway Construction Corporation built a 30 km section of the Ankara–Istanbul high-speed railway completed in 2014. In Europe, Chinese companies are involved in construction of the Belgrade–Budapest railway linking Serbia and Hungary. Moreover, in Southeast Asia, further high-speed rail projects with Chinese involvement are advancing in Thailand and under discussion in Vietnam. Although not designed for the same speeds, China has also exported 160 km/h electrified lines, such as the Boten–Vientiane railway in Laos, often described as part of a broader pan-Asian high-speed corridor.
Beyond completed and under-construction projects, China has signed agreements or placed bids for HSR lines in Russia, Venezuela, Argentina, Saudi Arabia, Brazil (São Paulo–Rio de Janeiro), and the United States. While many of these projects remain at the proposal or bidding stage, they reflect China's emergence as a competitor to established Japanese and European suppliers in the global high-speed rail market.

History

Precursor

The earliest example of a fast commercial train service in China was the Asia Express, a luxury passenger train that operated in Japanese-controlled Manchuria from 1934 to 1943. The steam-powered train, which ran on the South Manchuria Railway from Dalian to Xinjing, had a top commercial speed of and a test speed of. It was faster than the fastest trains in Japan at the time. After the founding of the People's Republic of China in 1949, this train model was renamed the SL-7 and was used by the Chinese Minister of Railways.

Early planning

State planning for China's current high-speed railway network began in the early 1990s under the leadership of Deng Xiaoping. He set up what became known as the "high-speed rail dream" after his visit to Japan in 1978, where he was deeply impressed by the Shinkansen, the world's first high speed rail system. In December 1990, the Ministry of Railways submitted to the National People's Congress a proposal to build a high-speed railway between Beijing and Shanghai. At the time, the Beijing–Shanghai Railway was already at capacity, and the proposal was jointly studied by the Ministry of Science and Technology of the [People's Republic of China|Science & Technology Commission], State Planning Commission, State Economic & Trade Commission, and the MOR. In December 1994, the State Council commissioned a feasibility study for the line.
Policy planners debated the necessity and economic viability of high-speed rail service. Supporters argued that high-speed rail would boost future economic growth. Opponents noted that high-speed rail in other countries was expensive and mostly unprofitable. Overcrowding on existing rail lines, they said, could be solved by expanding capacity through higher speed and frequency of service. In 1995, Premier Li Peng announced that preparatory work on the Beijing Shanghai HSR would begin in the 9th Five Year Plan, but construction was not scheduled until the first decade of the 21st century.

The "Speed Up" campaigns

In 1993, commercial train service in China averaged only and was steadily losing market share to airline and highway travel on the country's expanding network of expressways. The MOR focused modernization efforts on increasing the service speed and capacity on existing lines through double-tracking, electrification, improving grade, reducing turn curvature and installing continuous welded rail. Through five rounds of "Speed-Up" campaigns in April 1997, October 1998, October 2000, November 2001, and April 2004, passenger service on of existing tracks was upgraded to reach sub-high speeds of.
A notable example is the Guangzhou–Shenzhen railway, which in December 1994 became the first line in China to offer sub-high-speed service of using domestically produced DF-class diesel locomotives. The line was electrified in 1998, and Swedish-made X 2000 trains increased the service speed to. After the completion of a third track in 2000 and a fourth in 2007, the line became the first in China to run high-speed passenger and freight services on separate tracks.
The completion of the sixth round of the "Speed-Up" Campaign in April 2007 brought HSR service to more existing lines: capable of train service and capable of. In all, travel speed increased on, or one-fifth, of the national rail network, and the average speed of passenger trains improved to. The introduction of more non-stop services between large cities also helped to reduce travel time. The non-stop express train from Beijing to Fuzhou shortened travel time from 33.5 hours to less than 20 hours.
In addition to track and scheduling improvements, the MOR also deployed faster CRH series trains. During the Sixth Railway Speed Up Campaign, 52 CRH trainsets entered into operation. The new trains reduced travel time between Beijing and Shanghai by two hours to just under 10 hours. Some 295 stations have been built or renovated to allow high-speed trains.

The conventional rail v. maglev debate

The development of the HSR network in China was initially delayed by a debate over the type of track technology to be used. In June 1998, at a State Council meeting with the Chinese Academies of Sciences and Engineering, Premier Zhu Rongji asked whether the high-speed railway between Beijing and Shanghai still being planned could use maglev technology. At the time, planners were divided between using high-speed trains with wheels that run on conventional standard gauge tracks or magnetic levitation trains that run on special maglev tracks for a new national high-speed rail network.
Maglev received a big boost in 2000 when the Shanghai Municipal Government agreed to purchase a turnkey TransRapid train system from Germany for the rail link connecting Shanghai Pudong International Airport and the city. In 2004, the Shanghai Maglev Train became the world's first commercially operated high-speed maglev and remains the fastest commercial train in the world with peak speeds of and makes the trip in less than 7.5 minutes. Despite an unmatched advantage in speed, the maglev has not gained widespread use in China's high-speed rail network due to high costs, German refusals to share technology and concerns about safety. The price tag of the Shanghai Maglev was believed to be $1.3 billion and was partially financed by the German government. The refusal of the Transrapid Consortium to share technology and source production in China made large-scale maglev production much more costly than high-speed train technology for conventional lines. Finally, residents living along the proposed maglev route raised health concerns about noise and electromagnetic radiation emitted by the trains, despite an environmental assessment by the Shanghai Academy of Environmental Sciences saying the line was safe. These concerns have prevented the construction of the proposed extension of the maglev to Hangzhou. Even the more modest plan to extend the maglev to Shanghai's other airport, Hongqiao International Airport|Hongqiao] couldn't be completed. Instead, a conventional subway line was built to connect the two airports, and a conventional high-speed rail line was built between Shanghai and Hangzhou.
While maglev was drawing attention to Shanghai, conventional track HSR technology was being tested on the newly completed Qinhuangdao-Shenyang Passenger Railway. This standard gauge, dual-track, electrified line was built between 1999 and 2003. In June 2002, a domestically made DJF2 train set a record of on the track. The China Star train followed the same September with a new record of. The line supports commercial train service at speeds of and has become a segment of the rail corridor between Beijing and Northeast China. The Qinhuangdao-Shenyang Line showed the greater compatibility of HSR on conventional track with the rest of China's standard gauge rail network.
In 2004, the State Council in its Mid-to-Long Term Railway Development Plan, adopted conventional track HSR technology over maglev for the Beijing–Shanghai High Speed Railway and three other north–south high-speed rail lines. This decision ended the debate and cleared the way for rapid construction of standard gauge, passenger dedicated HSR lines in China.

Acquisition of foreign technology

Despite setting speed records on test tracks, the DJJ2, DJF2 and other domestically produced high-speed trains were insufficiently reliable for commercial operation. The State Council turned to advanced technology abroad but made it clear in directives that China's HSR expansion could not solely benefit foreign economies and should also be used to develop its own high-speed train building capacity through technology transfers. This would later allow the Chinese government through CRRC to make the more reliable Fuxing Hao and Hexie Hao trains. The CRH380 series of trains was initially built with direct cooperation from foreign trainmakers, but newer trainsets are based on transferred technology, just like the Hexie and Fuxing Hao.
In 2003, the MOR was believed to favor Japan's Shinkansen technology, especially the 700 series. The Japanese government touted the 40-year track record of the Shinkansen and offered favorable financing. A Japanese report envisioned a winner-take all scenario in which the winning technology provider would supply China's trains for over of high-speed rail. However, Chinese citizens angry with Japan's denial of World War II war crimes organized a web campaign to oppose the awarding of HSR contracts to Japanese companies. The protests gathered over a million signatures and politicized the issue. The MOR delayed the decision, broadened the bidding and adopted a diversified approach to adopting foreign high-speed train technology.
In June 2004, the MOR solicited bids to make 200 high-speed train sets that can run. Alstom of France, Siemens of Germany, Bombardier Transportation based in Germany and a Japanese consortium led by Kawasaki all submitted bids. With the exception of Siemens, which refused to lower its demand of CN¥350 million per train set and €390 million for the technology transfer, the other three were all awarded portions of the contract. All had to adapt their HSR train-sets to China's own common standard and assemble units through local joint ventures or cooperate with Chinese manufacturers. Bombardier, through its joint venture with CSR's Sifang Locomotive and Rolling Stock Co (CSR Sifang), Bombardier Sifang Transportation Ltd, won an order for 40 eight-car train sets based on Bombardier's Regina design. These trains, designated CRH1A, were delivered in 2006. Kawasaki won an order for 60 train sets based on its E2 Series Shinkansen for ¥9.3 billion. Of the 60 train sets, three were directly delivered from Nagoya, Japan, six were kits assembled at CSR Sifang Locomotive & Rolling Stock, and the remaining 51 were made in China using transferred technology with domestic and imported parts. They are known as CRH2A. Alstom also won an order for 60 train sets based on the New Pendolino developed by Alstom-Ferroviaria in Italy. The order had a similar delivery structure with three shipped directly from Savigliano along with six kits assembled by CNR's CRRC Changchun Railway Vehicles, and the rest locally made with transferred technology and some imported parts. Trains with Alstom technology carry the CRH5 designation.
The following year, Siemens reshuffled its bidding team, lowered prices, joined the bidding for trains and won a 60-train set order. It supplied the technology for the CRH3C, based on the ICE3 (class 403) design, to CNR's Tangshan Railway Vehicle Co. Ltd. The transferred technology includes assembly, body, bogie, traction current transforming, traction transformers, traction motors, traction control, brake systems, and train control networks.

Early passenger-dedicated high-speed rail lines

Between June and September 2005, the MOR launched bidding for high-speed trains capable of, as most of the planned mainlines were designed for speeds of or higher. Alongside the CRH3C, produced by Siemens and CNR Tangshan, CSR Sifang bid to supply 60 sets of CRH2C.
At that time, China's only passenger-dedicated high-speed railway was the Qinhuangdao–Shenyang line, which began operating in 2003 at speeds of up to along the Liaoxi Corridor in the Northeast. This situation changed quickly as China embarked on a high-speed rail construction boom.
In 2007, the journey from Beijing to Shanghai still took about 10 hours, with upgraded tracks on the Beijing–Shanghai Railway allowing maximum speeds of only. To expand capacity, the MOR ordered 70 16-car trainsets from CSR Sifang and Bombardier Sifang Transportation.
A major turning point came with the launch of the Beijing–Shanghai high-speed railway, the first line in the world designed for, which began construction on April 18, 2008. That same year, the Ministry of Science and the MOR introduced a joint action plan to foster indigenous innovation in high-speed trains. The MOR subsequently initiated three new train projects: the CRH1-350, CRH2-350, and CRH3-350. These represented a new generation of CRH trains with a top operating speed of. In total, 400 of these trains were ordered. On October 26, 2010, the first high-speed train developed indigenously within the CRH series, the CRH380A/AL, entered service on the Shanghai–Hangzhou High-Speed Railway.
After committing to conventional-track high-speed rail in 2006, the government launched an ambitious campaign to build a nationwide network of passenger-dedicated lines. Rail construction spending grew rapidly, from $14 billion in 2004 to $22.7 billion in 2006 and $26.2 billion in 2007. In response to the global financial crisis, this expansion was further accelerated as part of an economic stimulus program. Investments in new rail lines, including high-speed rail, reached $49.4 billion in 2008 and $88 billion in 2009. At the time the government planned to invest $300 billion to construct a HSR network by 2020, an early that plan that would later be dramatically exceeded.

Expansion

China's ambitious high-speed rail development began with the 2004 "Mid-to-Long Term Railway Network Plan," establishing a national grid of eight corridors totaling. The Hefei–Nanjing PDL opened April 19, 2008, followed by the Beijing–Tianjin intercity railway on August 1, 2008, featuring the first commercial service. Major milestones included the Wuhan–Guangzhou line, which set a world record with average speeds of, and the Beijing–Shanghai high-speed railway, designed for operation. By January 2011, China operated the world's longest high-speed network at.

Corruption and concerns

In February 2011, Railway Minister Liu Zhijun, a key proponent of HSR expansion in China, was removed from office on charges of corruption. The Economist estimates Liu accepted ¥1 billion of bribes in connection with railway construction projects. Investigators found evidence that another ¥187 million was misappropriated from the $33 billion Beijing–Shanghai high-speed railway in 2010.
Another top official in the Railways Ministry, Zhang Shuguang, was also sacked for corruption. Zhang was estimated to have misappropriated to his personal overseas accounts the equivalent of $2.8 billion.
After the political shake-up, concerns about HSR safety, high ticket prices, financial sustainability and environmental impact received greater scrutiny in the Chinese press.
In April 2011, the new Minister of Railways Sheng Guangzu said that due to corruption, safety may have been compromised on some construction projects and completion dates may have to be pushed back. Sheng announced that all trains in the high-speed rail network would operate at a maximum speed of beginning on July 1, 2011. This was in response to concerns over safety, low ridership due to high ticket prices, and high energy usage. On June 13, 2011, the MOR clarified in a press conference that the speed reduction was not due to safety concerns but to offer more affordable tickets for trains at and increase ridership. Higher-speed train travel uses greater energy and imposes more wear on expensive machinery. Railway officials lowered the top speed of trains on most lines that were running at to. Trains on the Beijing–Tianjin high-speed line and a few other inter-city lines remained at.
In May 2011, China's Environmental Protection Ministry ordered the halting of construction and operation of two high-speed lines that failed to pass environmental impact tests. In June, the MOR maintained that high-speed rail construction was not slowing down. The CRH380A trainsets on the Beijing–Shanghai high-speed railway could reach a top operational speed of but were limited to.
Under political and public pressure, the National Audit Office carried out an extensive investigation into the building quality of all high-speed rail lines. As of March 2011, no major quality defects had been found in the system. Foreign manufacturers involved in the Shanghai–Beijing high-speed link reported that their contracts called for a maximum operational speed of. From July 20, 2011, the frequency of train services from Jinan to Beijing and Tianjin was reduced due to low occupancy, renewing concerns about demand and profitability for high-speed services. Service failures in the first month of operation drove passengers back to pre-existing slower rail service and air travel; airline ticket prices rebounded due to reduced competition.

Wenzhou accident

On July 23, 2011, two high-speed trains collided on the Ningbo–Taizhou–Wenzhou railway in Lucheng District of Wenzhou, Zhejiang Province. The accident occurred when one train traveling near Wenzhou was struck by lightning, lost power and stalled. Signals malfunctioned, causing another train to rear-end the stalled train. Several carriages derailed. State-run Chinese media confirmed 40 deaths, and at least 192 people hospitalised, including 12 who were severely injured. The Wenzhou train accident and the lack of accountability by railway officials caused a public uproar and heightened concerns about the safety and management of China's high-speed rail system. Quality and safety concerns also affected plans to export cheaper high-speed train technology to other countries.
The train collision exposed poor management by the railway company. This fatal accident, which happened in the midst of corruption investigations into railway officials, led to greater scrutiny in the Chinese press and the populace concerning the HSR and on the railway company.
Following the deadly crash, the Chinese government suspended new railway project approvals and launched safety checks on existing equipment. A commission was formed to investigate the accident with a directive to report its findings in September 2011. On August 10, 2011, the Chinese government announced that it was suspending approvals of any new high-speed rail lines pending the outcome of the investigation. The Minister of Railways announced further cuts in the speed of Chinese high-speed trains, with the speed of the second-tier 'D' trains reduced from to, and to on upgraded pre-existing lines. The speed of the remaining trains between Shanghai and Hangzhou was reduced to as of August 28, 2011. To stimulate ridership, on August 16, 2011, ticket prices on high-speed trains were reduced by five percent. From July to September, high-speed rail ridership in China fell by nearly 151 million trips to 30 million trips.

Slowdown in financing and construction

In the first half of 2011, the MOR as a whole made a profit of ¥4.29 billion and carried a total debt burden of ¥2.09 trillion, equal to about 5% of China's GDP. Earnings from the more profitable freight lines helped to off-set losses by high-speed rail lines. As of years ending 2008, 2009 and 2010, the MOR's debt-to-asset ratio was respectively, 46.81%, 53.06% and 57.44%, and reached 58.58% by mid-year 2011. As of October 12, 2011, the MOR had issued ¥160 billion of debt for the year. But in the late summer, state banks began to cut back on lending to rail construction projects, which reduced funding for existing railway projects. An investigation of 23 railway construction companies in August 2011 revealed that 70% of existing projects had been slowed or halted mainly due to shortage of funding. Affected lines included the Xiamen–Shenzhen, Nanning–Guangzhou, Guiyang–Guangzhou, Shijiazhuang–Wuhan, Tianjin–Baoding and Shanghai–Kunming high-speed rail lines. By October, work had halted on the construction of of track. New projects were put on hold and completion dates for existing projects, including the Tianjin–Baoding, Harbin–Jiamusi, Zhengzhou–Xuzhou and Hainan Ring, were pushed back. As of October 2011, the MOR was reportedly concentrating remaining resources on fewer high-speed rail lines and shifting emphasis to more economically viable coal transporting heavy rail.
To ease the credit shortage facing rail construction, the Ministry of Finance announced tax cuts to interest earned on rail construction financing bonds and the State Council ordered state banks to renew lending to rail projects. In late October and November 2011, the MOR raised RMB 250 billion in fresh financing and construction resumed on several lines including the Tianjin–Baoding, Xiamen–Shenzhen and Shanghai–Kunming.
Financial pressures intensified as the MOR's debt reached ¥2.09 trillion by mid-2011. Bank lending restrictions halted construction on of track, affecting major lines including Xiamen–Shenzhen and Shanghai–Kunming. The government responded with tax cuts on financing bonds and ordered renewed bank lending, raising RMB 250 billion by late 2011.

Second boom

Recovery began in 2012 as the government renewed investments to stimulate the economy, increasing the MOR budget from $64.3 billion to $96.5 billion. Five new lines totaling opened by year-end, extending the network to. By 2014, 1,580 high-speed trains carried 1.33 million daily passengers, with major lines like Beijing–Shanghai and Shanghai–Nanjing achieving profitability. On December 28, 2013, China's high-speed rail network surpassed with the opening of several new lines.
In 2014, high-speed rail expansion gained speed with the opening of the Taiyuan–Xi'an, Hangzhou–Changsha, Lanzhou-Ürümqi, Guiyang-Guangzhou, Nanning-Guangzhou trunk lines and intercity lines around Wuhan, Chengdu, Qingdao and Zhengzhou. High-speed passenger rail service expanded to 28 provinces and regions. The number of high-speed train sets in operation grew from 1,277 pairs in June to 1,556.5 pairs in December.
In response to a slowing economy, central planners approved a slew of new lines including Shangqiu–Hefei–Hangzhou, Zhengzhou–Wanzhou, Lianyungang–Zhenjiang, Linyi–Qufu, Harbin–Mudanjiang, Yinchuan–Xi'an, Datong–Zhangjiakou, and intercity lines in Zhejiang and Jiangxi.
The government actively promoted the export of high-speed rail technology to countries including Mexico, Thailand, the United Kingdom, India, Russia and Turkey. To better compete with foreign trainmakers, the central authorities arranged for the merger of the country's two main high-speed train-makers, CSR and CNR, into CRRC.
By 2015, six high speed rail lines, Beijing–Tianjin, Shanghai–Nanjing, Beijing–Shanghai, Shanghai–Hangzhou, Nanjing–Hangzhou and Guangzhou–Shenzhen–Hong Kong were reporting operational profitability. The Beijing–Shanghai was particularly profitable, reporting a 6.6 billion yuan net profit.
In 2016, with the near completion of the National 4+4 grid, a new "Mid-to-Long Term Railway Network" Plan was drafted. The plan envisions a larger 8+8 high speed rail grid serving the nation and expanded intercity lines for regional and commuter services for large metropolitan areas of China. The proposed completion date for the network is 2030.
Since 2017, with the introduction of the Fuxing series of trains, a number of lines have resumed 350 km/h operations, such as Beijing–Shanghai HSR, Beijing–Tianjin ICR, and Chengdu–Chongqing ICR.
The HSR network reached in total length by the end of 2020. In 2025, the HSR network will reach a total length of 50,000 km and is expected to grow further.

Development and social impact

China's high-speed rail program is designed to provide a fast, reliable, and comfortable mode of transport across one of the world's most densely populated countries. Key policy objectives include:

Economic growth and competitiveness – By increasing passenger rail capacity and freeing conventional lines for freight, HSR enhances productivity and integrates labor markets. Freight services benefit from higher payload capacity at lower speeds, which are more profitable than passenger operations.
Stimulus – Construction projects have generated large-scale employment and boosted demand in steel, cement, and other sectors. Work on the Beijing–Shanghai high-speed railway alone mobilized about 110,000 workers.
Regional integration – HSR links major cities with secondary urban centers, expanding market potential and contributing to higher real estate values in connected areas.
Energy efficiency and sustainability – Electric locomotives consume less energy per passenger-kilometre than cars or aircraft and can use electricity from diverse sources, including renewables, reducing reliance on imported oil.
Domestic industry development – The HSR program has fostered a globally competitive rail manufacturing sector. Chinese companies have rapidly absorbed and localized foreign technology, and now export high-speed rail equipment. Six years after licensing the Shinkansen E2 design from Kawasaki, CRRC Sifang was able to produce the CRH2A without Japanese input.

Financial sustainability and expansion concerns

As of the end of 2023, China's HSR system has an accumulated debt of $839 billion due to opaque financing by local governments. Mounting financial concerns have prompted policy reassessment. As China prepares its 2026-2030 five-year plan, analysts have questioned whether certain newly built lines meet central government construction standards, particularly given the country's greater need for freight capacity rather than passenger-only services.
In terms of annual operating revenues and expenditures, only six lines break even while the rest have huge losses.
The financial strain has been attributed to overbuilding high-speed rail lines to places where demand is not warranted. Most of the newer lines have low passenger volumes, as many of their stations are located well outside centers of metro areas and without direct local highway nor light rail connections. Officials have used high-speed rail construction primarily to drive up land value for land sales, especially in third and fourth-tier cities. Some underused lines and stations are seeing minimal service or remaining unopened despite completed construction. The Reason Foundation has described China's HSR system a boondoggle due to the incurred massive financial losses.
In response to these concerns, the government introduced stricter approval criteria in 2021, requiring new lines duplicating existing routes to demonstrate 80% capacity utilization on existing lines, and mandating that new high-speed lines serve cities with at least 15 million annual trips.

Construction costs and financing

China achieved relatively low construction costs through standardization of designs and procedures, with average costs of $17–21 million per kilometer according to a 2019 World Bank report—about one-third lower than other countries. Standardized train tracks, rolling stock, and signal systems, combined with bulk purchasing by state-owned corporations, helped keep costs down.
Construction financing is highly capital intensive, with 40-50% provided by the national government through state-owned banks, 40% through Ministry of Railway bonds, and 10-20% by provincial and local governments. The China Rail Investment Corp issued approximately ¥1 trillion in debt from 2006 to 2010 to finance HSR construction.
Despite construction efficiency, most lines operate at losses initially. The Beijing-Tianjin intercity railway, for example, required several years to break even despite carrying over 41 million rides in its first two years, due to construction costs of ¥20.42 billion and annual operating costs of ¥1.8 billion including interest payments. The line achieved profitability by 2015. However, many other lines continue to operate at losses, with deficits typically covered by subsidies from local governments. Profits from freight rail transport are used to subsidise the losses from HSR passenger services.
Overall ridership continues growing as the network expands, and high-speed rail has become more affordable relative to wages. However, in 2016, high-speed rail revenue of ¥140.9 billion still fell short of interest payments of ¥156.8 billion on construction debt. Experts have raised concerns about operational efficiency, noting that China's rail staff productivity index of less than 0.05 is the lowest among countries with significant railway construction, despite the network being one of the world's most intensively used for both freight and passenger service.
In China, a large proportion HSR lines built on elevated viaducts, while most of the world's other HSR lines like Japan's Shinkansen system rarely use continuous elevated piers. China's HSR viaducts occupies less land and shortens construction timelines, since it is driven by the interests of government departments and planning agencies. However, elevated HSR lines makes for more difficult boarding, less seamless integration with existing urban transit systems, higher overall investment, decreased engineering safety, more complicated maintenance and repair, and presents serious impediments to emergency response in the event of an accident.

HSR versus other mass transportation modes

A 2019 study by the World Bank Group found that HSR fares in China are low compared to other countries and have attracted passengers from all income levels. It noted that HSR is "very competitive" with bus and aircraft transport for distances between 150 km and 800 km. Due to both frequency and high speeds, services operating at remain competitive with air travel for journeys of up to 1,200 km.
The expansion of high-speed rail has significantly reshaped China's domestic aviation market. Research by Cirium Ascend Consultancy in 2025 found that HSR has captured a dominant share of trips under, where it is often faster and more convenient when total travel time from home to boarding is considered. On average, passengers in major Chinese cities save 35–45 minutes reaching and clearing security at HSR stations compared with airports, due to stations' central locations, shorter access times, and quicker screening processes. This competitive advantage has led to a structural decline in short-haul flights. According to Cirium data, flights of or less fell from 26.4% of all domestic flights in 2011 to 15.9% in early 2025. Overall flight volumes more than doubled in the same period with airlines shifting capacity to longer domestic routes, international services, and regions not yet served by high-speed rail, such as parts of western China.
In China, planners have attempted to make high-speed rail a "door-to-door" service. The newest high-speed rail stations often lack direct connections to local highways, bus routes, and light rail networks, due to being located well outside established metro areas.

Track network

China's high-speed railway network is by far the longest in the world. The HSR network reached in total length by the end of 2024, with plans to expand to by 2030.

Development planning and evolution

The development of China's HSR network has been guided by the Medium- and Long-Term Railway Plan, first approved in 2004 with several major revisions.
The ambition of the program has constantly expanded over time through successive revisions:

2004 original plan: Targeted an HSR network of by 2020
2008 revision: Increased the target to by 2020 and removed speed restrictions to allow higher-speed lines
2016 revision: Dramatically increased targets to by 2020, by 2025, and by 2030
2021 strategy: The "Outline of the Railway-First Strategy for Building a Strong Transportation Nation in the New Era" set an ambitious target of by 2035

The 2016 targets have been significantly exceeded, with the network reaching the original 2030 goal by several years. However, current official planning has de-emphasized the 2035 targets in favor of more immediate goals, with the focus shifting to achieving by 2030. As China prepares its next five-year plan covering 2026–2030, policymakers face decisions about whether to continue the rapid expansion pace amid growing financial sustainability concerns.

National High-Speed Rail Grid

HSR lines are generally classified into the following types, covering both the main national grid and additional regional and connecting lines:

Passenger-dedicated lines with a design speed of, forming the backbone of the national network.
Regional lines connecting major cities with a design speed of, providing fast connections across provinces.
Intercity lines with a design speed of, serving metropolitan areas and offering more frequent stops for regional service.
Older lines constructed during the early phase of the HSR build out that carry high-speed passenger and express freight services with a design speed of.

There are also mixed-use connecting lines and upgraded conventional rail segments that allow high-speed trains to extend beyond dedicated HSR lines, operating at speeds of around.
High-speed trains on dedicated HSR corridors can generally reach. On mixed-use or regional lines, passenger services typically operate at peak speeds of. Recent technological developments include maglev trains achieving test speeds over 600 km/h and new-generation bullet trains capable of 400 km/h, potentially reducing Beijing–Shanghai travel time from four hours to three.
The centerpiece of China's HSR expansion is the national high-speed rail grid, which overlays mainly passenger-dedicated lines onto the existing railway network.

Evolution from 4+4 to 8+8 Grid

The original national HSR grid, known as the "4+4 grid," consisted of eight high-speed corridors—four north–south and four east–west—with a total length of. Most lines followed existing trunk routes and were designated for passenger traffic only, though some sections carried mixed passenger and freight services. This 4+4 grid was largely completed by 2015.
In July 2016, the network was reorganized into eight "vertical" and eight "horizontal" high-speed corridors, almost doubling the network.

Service

Rail operators

China Railway High-speed (CRH) is the high-speed rail service operated by state-owned China Railway, the national railway operator. Almost all high-speed rail lines, trainsets, and related services in China are owned and managed by China Railway under the CRH brand. The main exceptions are the Shanghai Maglev Train, which is operated by the Shentong Metro Group, and the Guangzhou–Shenzhen–Hong Kong Express Rail Link, which is jointly operated by China Railway and the Hong Kong-based MTR Corporation.
Although both classified as high-speed rail, the Shanghai Maglev often is not counted as part of the national high-speed rail network, while XRL is fully integrated into the national network of the CRH. China has the world's only commercial maglev high-speed train line in operation. The Shanghai Maglev Train, a turnkey Transrapid maglev demonstration line long. The trains have a top operational speed of and can reach a top non-commercial speed of. It opened for operations in March 2004, and transports passengers between Shanghai's Longyang Road station and Shanghai Pudong International Airport. There have been numerous attempts to extend the line without success. A Shanghai-Hangzhou maglev line was also initially discussed but later shelved in favour of conventional high-speed rail.
Two other Maglev lines, the Changsha Maglev and the Line S1 of Beijing, were designed for commercial operations with speeds lower than. The Fenghuang Maglev opened in 2022 while the Qingyuan Maglev is under construction.

Ridership

China Railway reports the number of passengers carried by high-speed EMU train sets and this figure is frequently reported as high-speed ridership, even though this figure includes passengers from EMU trains providing sub-high speed service. In 2007, CRH EMU trains running on conventional track upgraded in the sixth round of the "Speed-up Campaign" carried 61 million passengers, before the country's first high-speed rail line, the Beijing–Tianjin intercity railway, opened in August 2008.
In 2018, China Railway operated 3,970.5 pairs of passenger train service, of which 2,775 pairs were carried by EMU train sets. Of the 3.313 billion passenger-trips delivered by China Railway in 2018, EMU train sets carried 2.001 billion passenger-trips. This EMU passenger figure includes ridership from certain D- and C-class trains that are technically not within the definition of high-speed rail in China, as well as ridership from EMU train sets serving routes on conventional track or routes that combine high-speed track and conventional track. Nevertheless, by any measure, high-speed rail ridership in China has grown rapidly with expansion of the high-speed rail network and EMU service since 2008.
China is the third country, after Japan and France, to have one billion cumulative HSR passengers. In 2018, annual ridership on EMU train sets, which encompasses officially defined high-speed rail service as well as certain sub-high-speed service routes, accounted for about two-thirds of all regional rail trips in China. At the end of 2018, cumulative passengers delivered by EMU trains is reported to be over 9 billion.

Safety

China's HSR network has had one major reported accident, the Wenzhou train collision, which happened on July 23, 2011, in which 40 people died, 172 were injured, and 54 related officials blamed and punished. According to a 2014 World Bank report, the incident was attributed to inadequate testing of a new design for signaling equipment, which lacked proper fail-safe features. The accident has prompted major reforms, as well as a more detailed examination of HSR construction which previously proceeded with little oversight.
Since then, operations have maintained an exemplary safety record.

Fastest trains in China

The "fastest" train commercial service can be defined alternatively by a train's top speed or average trip speed.

The fastest commercial train service measured by peak operational speed is the Shanghai Maglev Train which can reach. Due to the track's limited length of, the maglev train's average trip speed is only. During testing in 2003, the maglev train achieved the Chinese record speed of.
The fastest commercial train service measured by average train speed is the CRH express service on the Beijing–Shanghai high-speed railway, which reaches a top speed of and completes the journey between Shanghai Hongqiao and Beijing South, with two stops, in 4 hours and 24 min for an average speed of, the fastest train service measured by average trip speed in the world.
The fastest timetabled start-to-stop runs between a station pair in the world are trains G27/G39 on the Beijing–Shanghai high-speed railway averaging running non-stop between Beijing South to Nanjing South before continuing to other destinations.
The top speed attained by a non-maglev train in China is by a CRH380BL train on the Beijing–Shanghai high-speed railway during a testing run on January 10, 2011.

Longest service distance

The trains G403/404 and G405/406 for the - service, which began service on January 1, 2017, became the longest high-speed rail service in the world. It overtook the G529/530 trains for the - Beihai service, which had set the previous record on July 1, 2016.
