Rail transport in China

The opening of the short-lived Woosung Road, the first railway in China, between Shanghai and Wusong in 1876.

The first recorded railway track to be laid in China was a 600-metre (1,969 ft)-long miniature gauge demonstration line that a British merchant assembled outside the Xuanwumen city gate at Beijing in 1865 to demonstrate rail technology.[12] The Qing government was uninterested and had the line dismantled. The first railroad to enter commercial service was the Woosung railway, a 9.25 mi (14.89 km) railway from Shanghai to Woosung (modern Shanghai's Baoshan District) which opened in 1876. This was also built by the British, without approval from the Qing government, which had the line dismantled one year later. Until the defeat of China in the First Sino-Japanese War, the government remained hostile toward railway construction. Beginning in 1895, the government began to grant rail concessions to foreigners, and permitted direct connection to the capital Beijing.

Zhan Tianyou, the "father of China's railways"

By 1911, there were about 9,000 km (5,592 mi) of railroads in China, mostly designed, built, owned and operated by foreign companies. This was still well behind the industrialized world, the United States had roughly 380,000 km (236,121 mi) of rail at the time.[13] The first indigenous-designed and -constructed railway by Chinese was the Beijing-Zhangjiakou Railway built from 1905 to 1909, a difficult job due to the mountainous terrain. The chief engineer of this railway was Zhan Tianyou, who is known as the Father of China's Railway.[14][15]

During the Republic of China era from 1912 until 1949, the development of the railway network in China slowed due to repeated civil wars and the invasion of Japan in the Second Sino-Japanese War. One of the few exceptions was in Northeastern China (Manchuria). The Russian Empire opened the Chinese Eastern Railway in 1901; after the Russo-Japanese War (1904–1905), the Japanese gained control of the portion of the Chinese Eastern Railway south of Changchun, using it to create the South Manchuria Railway Company (SMR) in 1906; this company was often referred to as "Japan's East India Company in China" due to its extensive influence in the political and economic situation of Manchuria. During the reign of the Fengtian warlords from 1912 till 1931, numerous privately owned railway companies were formed. Some of the railway investment in the late 1930s was financed by the China Development Finance Corporation associated with businessman and statesman T. V. Soong.[16]

After the Japanese staged the Mukden Incident on 18 September 1931 as a pretext for invading Manchuria and the subsequent establishment of a puppet state called "Manchukuo", private railways were nationalized and merged to form the Manchukuo National Railway (MNR). In 1935, the Japanese bought the northern portion of the Chinese Eastern Railway from the Soviet Union and merged it into the MNR. In addition to the MNR and SMR, several other railway companies were established in the Japanese-occupied parts of China, including the North China Transportation Company, the Central China Railway, and the East Manchuria Railway. In 1945, just after the Second Sino-Japanese War, there were 27,000 km (16,777 mi) of rail, of which nearly half – 13,000 km (8,078 mi) – was located in Manchuria.[17]

The opening ceremony of the Chengdu–Chongqing Railway in 1953. The Chengyu Railway was the first railroad built after the founding of the People's Republic of China in 1949.

After the establishment of the People's Republic of China, the new government under Mao Zedong invested heavily in the railway network. From the 1950s to the 70s, lines, especially those in western China, were expanded. One example is the 1,900 km (1,181 mi) railway from Lanzhou to Ürümqi, which was built between 1952 and 1962. In Southwestern China, where difficult terrain prevails, several mountain railways were constructed, such as the Baoji–Chengdu railway, built in the 1950s, and the Chengkun railway, built in the 1970s. The railway to Tibet, one of the highest in the world, was finally completed and opened to the public in 2006. Today, every province-level entity of China, with the exception of Macau, is connected to the railway network.

Not only has the Chinese railway network expanded in size since 1949, but it has also seen great technological advances. Before the 1980s, most of the railways were powered by steam. China's first diesel locomotive, the Dongfeng, was introduced in 1958 and their first production model diesel, the DF4, was introduced in 1969. However, the early dieselization efforts were slowed by problems with the early DF4s and steam locomotive production continued into the late 1980s. During the 1980s and 90s, diesel and electric locomotives replaced the steam engines on main lines. However, steam locomotives didn't retire from some provincial railways until the 21st century. In December 2005, the world's last regular revenue mainline steam train finished its journey on the Jitong railway, marking the end of the steam era. Nevertheless, there are still some steam locomotives used in the industrial railways in China.

Rail in China expanded greatly beginning in 1965 with the Third Front campaign to develop basic industry and national defense industry in China's rugged interior in case of invasion by the Soviet Union or the United States.[18]^{: 4, 222–223} The primary achievement of railroad construction during the Third Front construction was the building of ten new interprovincial lines.[18]^: 203 Building the Chengdu-Kunming and the Guiyang-Kunming lines linked all southwest provincial capitals using rail for the first time.[18]^: 203 The Xiangfan-Chongqing and Hunan-Guizhou connected the central and western provinces by rail for the first time.[18]^: 203The additional rail built during this period greatly decreased travel time in the country's interior.[18]^: 222

From 1990 to 2001, on average some 1,092 km (679 mi) of new railways, 837 km (520 mi) of multiple-track, and 962 km (598 mi) of electrified railways were opened to traffic annually, 2.4-fold, 1.7-fold and 1.8-fold increases respectively over the previous 10 years. At the end of 2004, railways in operation reached 74,200 km (46,106 mi), including 24,100 km (14,975 mi) of multiple track and 18,900 km (11,744 mi) of electrified railways.

Since 1997, train speed has been raised significantly six times. The top speed of express trains increased from 120 to 200 km/h (75 to 124 mph), and passenger trains can reach maximum speed of 350 km/h (220 mph) on some sections of the arterial railways.

In March 2013, the Ministry of Railways was dissolved and its safety and regulation duties were taken up by the Ministry of Transport, inspection duties by the State Railway Administration and construction and management by the China Railway Corporation (CR).

In 2020, China Railway announced plans to expand the railway network by 33% or about 95,000 kilometres (59,030 mi), aiming to connect all cities with a population of over 200,000 by rail, and all with a population of over 500,000 by high-speed rail before 2035. As of July 2020, 95% of cities over 1 million have been connected by high-speed rail.[19][20]

The China Railway Corporation assumed most of the assets of the Ministry of Railways and continues to manage the railways at three levels—the national level, the bureau or subsidiary company level, and the station level. Below are the 18 rail bureaus of the China Rail Corporation and the number of passenger stations each bureau managed in 2013.[23] The National Railway Administration has seven oversight bureaus, based in Shenyang, Shanghai, Guangzhou, Chengdu, Wuhan, Xian and Lanzhou, to oversee these China Railway bureaus.

In 2013, railway transport generated ¥605 billion in revenues, an increase of 14.1% from the year before.[22]

To meet growing demand for rail service, the state is making large investments in rolling stock and infrastructure. In 2013, investments in rail totaled ¥808.8 billion, of which ¥662.3 billion on rail infrastructure, and ¥146.5 billion on rolling stock.[1]

The railways employed 2,184,400 workers in 2013, an increase of 139,000 from the year before.[22] Worker output averaged Y482,600 per person.[22]

In 2014, the railways consumed 16.526 million tonnes of coal equivalent of energy, a decrease of 4.6% or 801,000 tonnes from 2013.[1] It took 4.51 tonnes of coal equivalent to transport one million tonne-km of freight.[1]

The 2 ft 6 in (762 mm) gauge Jiayang Coal Railway in Sichuan Province, is the only steam train in operation, which is usually full of tourists in holidays.[31]

• Standard gauge: 79,685 kilometres (49,514 mi) 1,435 mm (4 ft 8+1⁄2 in) gauge (2008)
• Metre gauge: 466 kilometres (290 mi) 1,000 mm (3 ft 3+3⁄8 in) (Kunming–Hai Phong railway)
• Narrow gauge: 3,600 kilometres (2,200 mi) 750 mm (2 ft 5+1⁄2 in) gauge local industrial lines (1998 est.)

Sixteen major rail corridors consisting of eight running north–south, called verticals, eight running east–west, called horizontals, connect 81 major cities.[32] The 16 mainlines were designated in January 2001, when some 3,980 kilometres (2,470 mi) of the lines were still unbuilt. At that time, the existing mainlines accounted 43% of the railroads in the country but carried 80% of the passengers.[32] The last of the vertical mainlines was completed in 2009 and the last horizontal line opened in 2010.[33]

The 8 horizontal and 8 vertical mainlines of Chinese railway

The Guiyang–Guangzhou High-Speed Railway under construction in Yangshuo, Guangxi in August 2013.

In the past decade, China has been building an extensive high-speed rail grid that is overlaid onto the existing railway network. This grid is composed of eight high-speed rail corridors, four verticals and four horizontals with a total length of 12,000 km (7,456 mi). Most of the new lines follow the routes of existing trunk lines and are designated for passenger travel only. Several sections of the national grid, especially along the southeast coastal corridor, were built to link cities that had no previous rail connections. Those sections will carry a mix of passenger and freight. High-speed trains on passenger dedicated lines can generally reach 300–350 km/h (190–220 mph). On mixed-use HSR lines, passenger train service can attain peak speeds of 200–250 km/h (120–160 mph). This ambitious national grid project was planned to be built by 2020, but the government's stimulus has expedited time-tables considerably for many of the lines.

Railway stations in China are classified into six classes: special, first, second, third, fourth and fifth. A special class station can handle at least 60,000 passengers and 20,000 pieces of baggage, load at least 750 freight carriages or assign at least 6,500 carriages per day. A first class station can handle at least 15,000 passengers and 1,500 pieces of baggage, load 350 carriages or assign 3,000 carriages per day. A second class station can handle at least 5,000 passengers and 500 pieces of baggage, load 200 carriages or assign 1,500 carriages per day. In 2008, there were 5,470 train stations, including 50 special class stations, 236 first-class stations, 362 second-class stations and 936 third-class stations.[4]

The Beipan River Bridge on the Liupanshui–Baiguo railway in Guizhou of southwest China, was the highest railway bridge in the world from 2001 to 2016. The bridge deck is 275 metres (902 feet) above the Beipan River in a deep gorge.

The rail network across China's diverse topography makes extensive use of bridges and tunnels. In recent years, advances in bridge-building and tunneling techniques have enabled Chinese railroad builders to reduce overall track length and increase train speeds on rail lines through rugged terrain. The Yichang–Wanzhou railway, built from 2003 to 2010 across the karst landscape between Wuhan and Chongqing, has 159 tunnels and 253 bridges, which account for 74% of the railway's total length.[58] High-speed rail lines are often built on elevated tracks to reduce the need to acquire land and involve very long bridges. The Beijing–Shanghai high-speed railway has three of the longest railroad bridges in the world with lengths of 164.8 kilometres (102.4 miles), 113.7 kilometres (70.6 miles) and 48.15 kilometres (29.92 miles). The Beipan River Shuibai Railway Bridge built in 2003 in Guizhou is the world's highest railway bridge. Its bridge deck is 275 metres (902 feet) above the Beipan River in a deep gorge.

As of 2008, there were 47,524 railway bridges in use in mainland China (excluding Hong Kong and Taiwan), including 872 major bridges over 500 metres (1,600 feet) in length.[4]

The Greater Khingan Ridge Tunnel on the Harbin–Manzhouli railway, built in 1904.

As of 2008, there were 6,102 railway tunnels in use in mainland China (excluding Hong Kong and Taiwan), including 183 over 3 kilometres (1.9 miles) and seven over 10 kilometres (6.2 miles) in length.[4] The first railroad tunnel was built in 1888 by the Qing dynasty in Taiwan. The Shi-chiu-lin Tunnel near Keelung, 261 metres (856 feet) long, is now a historical landmark. The oldest rail tunnel on the mainland is the 3,077.2 metres (10,096 feet) Greater Khingan Rail Ridge built in 1904 on the Chinese Eastern Railway in modern-day Inner Mongolia. The longest tunnel in China is the 27,848 metres (91,365 feet) Taihangshan Tunnel on the Shijiazhuang–Taiyuan high-speed railway in northern China. Several longer tunnels are under construction.

MV Yue Hai Tie 1 Hao, one of the ferries running across Qiongzhou Strait, forming part of Guangdong–Hainan railway

The most notable train ferries in China are the Guangdong–Hainan Ferry, across the Qiongzhou Strait between the Leizhou Peninsula on the south coast of Guangdong and the island of Hainan, and the Bohai Train Ferry, connecting the Liaodong and Shandong Peninsulas across the Bohai Bay. These two ferries began operating, respectively, in 2003 and 2007.

A river ferry carries trains on the Xinyi–Changxing railway across the Yangtze River at Jingjiang, halfway between Nanjing and Shanghai. In the first half of the 20th century, all trains traversing the Yangtze River required ferries. Since the completion of the Wuhan Yangtze River Bridge in 1953, at least fifteen railway bridges and two subway tunnels now span the Yangtze.

Passenger trains are identified by their class of service (usually indicated by letter prefix for faster trains) followed by three to four numerals indicating the bureau and region of operation. The syllables in bold will be used in broadcasting in train stations, for example, C1234 will be pronounced as cheng-1234.

Trains starting with G, C, D are run by CRH EMUs and form the high-/higher-speed network in China, while other trains are locomotive-hauled conventional trains.

Regular services stopping at all stations remain mostly limited to remote areas lacking high-speed services, including many ethnic minority regions, and are heavily subsidized.[63][64][65]

The newer high-speed train service (Classes G, C and D) that use electrical multiple units have the following types of cars:[66][67]

Sleeping compartment (WR) of CRH2 trainset

First class coach (ZY) of CRH5A trainset

Business class coach (SW) of CRH380CL trainset

Second class coach (ZE) of CRH380A trainset

Dining car (CA) of CRH1 trainset

• High-speed sleeper carriages (WR), with capacity for 40, have 20 enclosed compartments each with two berths. A few trains have a deluxe high-speed sleeper (WG), with capacity for 40 and eight compartments that are more spacious. High-speed sleepers are found on some D-class overnight trains.
• First class coaches (ZY), with capacity for 44–72, have partially reclining plush seats and power outlets, there are four seats in each row.
• Business class coaches (SW), with capacity for 24–56, are found on some high-speed train sets such as the CRH380A and CRH380BL. They have reclining sofa seats with flat screen TVs, power outlets and other amenities. Only available on G trains and some D trains.
• Second class coaches (ZE), with capacity for 83–101, have the most affordable seats on high-speed trains, there are five seats in each row.

Most high-speed trains have dining cars (CA). Some have sight-seeing cars (ZYG, ZEG, SWG) that are attached to the front or end of the train.

The following types of cars are found on traditional, non-high-speed trains:[68]

Deluxe soft sleeper

Soft sleeper (RW)

Semi-compartment hard sleeper (YW) on 25T coaches

Open hard sleeper (YW)

Soft seat (RZ)

Hard seat (YZ) on non-air-conditioned coaches

• Deluxe soft sleeper, with capacity for 20–36, have two-berth compartments with private bathroom and television. Most long-distance trains carry this carriage along with Soft sleeper carriages.
• Soft sleeper carriages (RW), with capacity for 36 (50 in double-decker cars (SRW)), have enclosed, lockable compartments with four sleeping berths. The upper berths can be folded up to allow for seating in the lower berths.
• Hard sleeper carriages (YW), with capacity for 60–66 (76–80 in double-decker cars (SYW)), have 11 open bays or semi-compartments with six sleeping berths in each. Within each bay, the sleeping berths are stacked three on each side (lower, middle and upper). The lower berths cost the most and the upper berths, the least.
• Soft seat carriages (RZ), with capacity for 72–88 (108–110 in double-decker cars (SRZ)), have plush seats and more legroom and are available only on some K, T and Y class trains.
• Hard seat carriages (YZ), with capacity for 116–128 (170–180 in double-decker cars (SYZ)), have cushioned but stiff seats and provide the most basic seating option on non-high speed trains (Classes K, T, Z, L, regular fast, regular). On crowded trains, riders with standing room tickets will stand in the aisles of hard seat cars.

Long-distance trains have dining cars (CA).

Demand for tickets increases dramatically during the Chinese New Year and the two Golden Week holiday in early May and October, as many migrant workers and students return home and travelers go on vacation. The Golden Weeks are holidays organized May Day (1 May) and National Day (1 October). Chinese New Year also called the Spring Festival, follows the lunar calendar and is in January or February.

In 2009, the duration of the May holidays was shortened from one week to a long weekend, but holiday traffic remained strong, setting a one-day record of 6.54 million passengers carried over the Chinese rail network on 1 May 2009.[69]

The month-long period before, during and after the Chinese New Year is known as Chunyun or "spring transport" for the China's railways. During this period, train service increases to meet the demand from one of the largest annual human migrations in the world. Since railway transport is the cheapest method for long-distance travelers in China, the railway is the most important transport method during the Chunyun period. For example, during the 40 days of the 2007 Chunyun period, it is estimated that 156 million passengers rode trains, which corresponds to 3.9 million passengers per day, compared to the overall average of 2.4 million per day. To make the situation even worse, traffic is highly imbalanced: before the Chinese New Year, passengers mainly travel from the large cities and after the holiday, the traffic reverses. Although hundreds of temporary trains are operated, train tickets are still in short supply. Trains are very crowded during this period, for example; a passenger car with 118 seats may accommodate more than 200 people.

International passenger train services are available to destinations in:

• Kazakhstan, Mongolia, and Russia. These countries use 1,520 mm (4 ft 11+27⁄32 in) gauge, so there is a break-of-gauge.
• Hong Kong SAR, Laos, and North Korea. These use standard gauge.
• Vietnam, although Vietnam predominately uses 1,000 mm (3 ft 3+3⁄8 in) rail gauge, the line running up from Hanoi to the border between China and Vietnam, which is the only line currently receiving international passenger train service from China, is dual-gauged. Therefore, there are no break of gauge problems in the service.

An MTR Vibrant Express train at Guangzhou South railway station

The Guangzhou–Kowloon through train is jointly operated by the Hong Kong MTR and China Rail Corporation.

Train services to Hong Kong terminate at the Hung Hom station in Kowloon. Within Hong Kong the cross-boundary services use the tracks of the East Rail line. There are three through-train routes, Beijing line (to/from Beijing), Shanghai line (to/from Shanghai) and Guangdong line (to/from Zhaoqing and Guangzhou East). An express train service linking Hong Kong West Kowloon and Guangzhou entered service in September 2018. This new express rail line will reduce the train travel time between Hong Kong and Guangzhou from 2 hours to 1 hour.

Left: The Ji'an Yalu River Railway Bridge between Ji'an, Jilin and Manpo, Chagang Province of North Korea. Right: Sino-Korean Friendship Bridge near the mouth of the Yalu River between Dandong, Liaoning and Sinuiju, North Pyongan Province.

There are rail crossings along the border with North Korea at Dandong, Ji'an and Tumen.

Dandong, in Liaoning, is 277[78] km (172 mi) by regular train and 223 km (139 mi) by CHR south of Shenyang at the mouth of the Yalu River across from Sinuiju in North Korea's North Pyongan Province. This is the most heavily used rail connection between the two countries. Ji'an, upstream on the Yalu in Jilin and 400 km (250 mi) by rail from Siping, connects to Manpo in Chagang Province. Tumen, also in Jilin and 527 km (327 mi) east of Changchun is located across the Tumen River from Namyang, North Hamgyong Province.

There are four weekly trains with hard and soft sleepers from Beijing to Pyongyang, as well as a weekly carriage attached to the Vostok train from Moscow via Harbin, Shenyang and Dandong.[79]

China's three rail crossings into Russia are all located along the eastern section of the border between the two countries.

A train leaving Russia and entering China at Manzhouli.

The crossings at Manzhouli and Suifenhe are at either ends of the Trans-Manchurian Railway, which was a shortcut for the Trans-Siberian Railway built through northeastern China in the early 1900s. Manzhouli, in the Hulunbuir region of northern Inner Mongolia, is China's busiest inland port. It borders Zabaykalsk in Zabaykalsky Krai of Russia's Transbaikal region and handles the bulk of the bilateral freight trade and one of the Beijing-Moscow passenger train routes. Suifenhe, in southern Heilongjiang, borders the town of Pogranichny in Primorsky Krai of the Russian Far East. The rail station on the Russian's side is called Grodekovo. Freight trains from Harbin to Khabarovsk and Vladisvostok pass through Suifenhe. As of November 2008, there was no through passenger service, but one could travel along this route with transfers in Suifenhe, Grodekovo and Ussuriysk.[80]

Rail cars in Manzhouli, the busiest inland port in China.

A third rail connection is located further south at Hunchun in eastern Jilin bordering Kraskino, near the southwest tip of Primorsky Krai. The station on the Russian side, called Makhalino, is located on the Ussuriysk-Khasan-North Korean border line, about 41 km (25 mi) from Khasan. This border crossing began operating in February 2000,[81] and saw only a minor amount of traffic (678 railcars of lumber) over the next two years. The line was closed in 2002–2003, reopened in 2003, but, as of the summer of 2004, it was still reported as seeing little traffic.[82] The line was closed between 2004[83] and 2013.[84] As of 2011–2012, plans existed for reopening it, primarily to be used for shipping coal and mineral ores from Russia to China;[83][85] The border crossing reopened, initially in a trial mode, in 2013.[84]

There are two weekly passenger trains in each direction between Beijing and Moscow.[79] The No. 19/20 trains travel 8,961 kilometres (5,568 mi) via Harbin, Manzhouli and the Trans-Siberian Railway.[79] The No. 3/4 trains, take a shorter route of 7,622 kilometres (4,736 mi), through Mongolia via the Trans-Mongolian Railway and has the two-berth deluxe soft sleeper cars.[79] Both journeys are among the longest train services in the world.

Changing bogies at Erenhot on the Sino-Mongolian border

The lone rail connection with Mongolia's railways is located at Erenhot, in Xilingol League of central Inner Mongolia, which borders Zamyn-Üüd in Mongolia's Dornogovi Province.

There are two trains every week departing from Beijing and Hohhot to Ulaanbaatar, along with five trains per week from Erenhot. As with rail service to Russia, trains from China need to change bogies in Erenhot, since Mongolia uses broad gauge.

There are two rail crossings on the China–Kazakhstan border, at Alashankou and Khorgas, both located in the northern part of the Xinjiang. They are the only international rail outlets in western China.

The westernmost point on the Northern Xinjiang Railway at the Kazakh border.

At Alashankou, in the Bortala Mongol Autonomous Prefecture, the Northern Xinjiang railway passes through the Dzungarian Gate to the town of Dostyk, in Kazakhstan's Almaty Province and connects to Qazaqstan Temir Zholy (Kazakhstan's railway system). This crossing, opened in 1990, forms a New Eurasian Land Bridge, allowing trains from Lianyungang on the East China Sea to reach Rotterdam on the North Sea. There are two weekly passenger trains (one Kazakh and one Chinese) from Almaty to Ürümqi, the capital of Xinjiang. There are differing reports on which of the two is more comfortable, and the Chinese train is generally of a higher standard than the Kazakh train.

Khorgas, in the Ili Kazakh Autonomous Prefecture, is located southwest of Alashankou in the Ili Valley. The town on the Kazakh side of the border in Almaty Province, has the same name, Korgas. Here, the Jinghe–Yining–Khorgas railway, a 286-km fork off the main Northern Xinjiang line built in 2009, meets the Zhetigen-Korgas railway, a 239-km branch from the Turkestan–Siberian Railway completed by Kazakhstan in 2011.[86][87] The Khorgas crossing, opened in December 2012, provides a more direct route from Ürümqi to Almaty.[87][88]

Dual gauge tracks at Đồng Đăng in Vietnam accommodates both metre gauge trains from Hanoi and standard gauge trains from Nanning and other cities in China.

There are two rail connections between China and Vietnam, at the Friendship Pass and Hekou. At the Friendship Pass on the border between Pingxiang, Guangxi Zhuang Autonomous Region and Đồng Đăng in Vietnam's Lạng Sơn province, the Hunan–Guangxi railway connects to the dual gauge Hanoi-Đồng Đăng Line. The crossing, opened in 1955, has displaced the older Hekou crossing as the primary rail link between the two countries. There are twice weekly trains from Beijing to Hanoi and both traverse the Friendship Pass. The trains consist of a typical T style Chinese express from Beijing to Đồng Đăng. The train may require passengers to detrain in Nanning for 5 hours (especially on the northbound service); a lounge area with reclining chairs is available for Soft Sleeper passengers.

At Hekou, the narrow-gauge Kunming–Hai Phong railway from Kunming, in Yunnan crosses into Vietnam's Lào Cai province. This line, also known as the Yunnan–Vietnam railway, was built by France from 1904 to 1910 though rugged terrain. Cross-border service on this line ceased in late 2000, but freight trains have kept this crossing operational.

A railway connecting Kunming to the border with Laos is under construction, which connects to another under construction line linking the border to the Lao capital Vientiane, which already has a real link to Thailand. The line was opened on 3 December 2021 at the 60th anniversary of China–Laos relations.[89]

In recent years, China has been actively exploring and promoting the extension of its railway network to neighboring countries and distant regions including the Russian Far East, Southeast Asia, South Asia, Central Asia, the Middle East and even North America.

Macau SAR is currently served by Macau Light Rail Transit completed in 2019.[90] A "Hengqin Branch Line" is planned for the network, which will connect the network directly to Hengqin, part of Zhuhai in Guangdong.[91][92] The extension line is planned to connect with Guangzhou–Zhuhai intercity railway at the Hengqin station which is part of its first phase extension project that is scheduled to complete in year 2018, and would facilitate seamless cross border rail transit.[93]

Additionally, the city of Guangzhou, Zhongshan, and Zhuhai have proposed the construction of a new "Guangzhou-Zhongshan-Zhuhai-Macau Intercity Railways" which could further connectivity on the west bank of Pearl River Delta.[94]

In November 2008, the transport ministries of Russia and the China signed an agreement to build one more link between the railway systems of the two countries. One project involves the Tongjiang-Nizhneleninskoye railway bridge across the Heilongjiang (Amur) River, connecting Tongjiang in Heilongjiang with Nizhneleninskoye, a village in Russia's Jewish Autonomous Oblast. The project construction began in 2014 and was estimated to be complete in year 2016, however the project had been halted by funding problems and construction delay by Russian side. Additional funding have been injected to the project in year 2017 which resolved the funding problem, and the project is currently estimated to be complete in year 2018.[95][96][97][98]

Additionally, a high speed rail link between Hunchun and Vladivostok have been proposed and discussed.[99][100][101][102]

In October 2014, the Mongolian parliament approved two standard gauge cross-border railways to China.[103][104] One line would run 240 kilometres (150 mi) from the Tavan Tolgoi coalfields of Ömnögovi Province to the border at Gashuun Suukhait and cross into China at Ganqimaodu in Urad Middle Banner, part of Inner Mongolia's Bayan Nur Municipality.[103][104] The other would run from central Mongolia to Bichigt in Sükhbaatar Province and cross into China at Zhuengadabuqi of East Ujimqin Banner, under Inner Mongolia's Xilingol League.[103][104]

Since 1997, the governments of China, Kyrgyzstan and Uzbekistan have discussed the building of a 476 kilometres (296 mi) railway across the Tian Shan mountains from Kashgar in the western Tarim Basin of the Xinjiang to the Ferghana Valley via southern Kyrgyzstan.[105] In March 2013, the China Road and Bridge Corp., an engineering firm, submitted a feasibility study to the Kyrgyz government, which found the project to be too expensive.[105] In December 2013, Kyrgyz president Almazbek Atambayev expressed his preference for an alternative line that would connect the northern and southern halves of the country.[106]

On 5 May 2014, the Export-Import Bank of China lent Uzbekistan $350 million for the construction of a railway through the Kamchik Pass that would connect the Fergana Valley with the rest of Uzbekistan.[107] On 12 May 2014, China's paramount leader, Xi Jinping, and Turkmenistan's president, Gurbanguly Berdymukhamedov, signed a declaration to study the possibility of inviting Chinese companies to build a cross-border railway linking the two countries.[108] On 22 May 2014, the Foreign Minister of Kyrgyzstan reportedly suggested inviting China to join in another regional railway project linking Russia, Central Asian states and the Persian Gulf.[109]

China and Nepal signed a series of agreements including a railway link connecting Kathmandu to China's railway network in 2018. The China–Nepal Railway will connect Kathmandu and Shigatse, Tibet.[110] Survey of the Kerung-Kathmandu section will be completed by early 2019, and construction is expected to be completed in six years.[111] The construction is in progress as of September, 2023.

Since 2007, Chinese and Pakistani authorities have explored the possibility of building the Khunjerab Railway, which would cross the Karakorum Mountains and connect Kashgar with Havelian in the Abbottabad District of northern Pakistan. In June 2013, the Pakistani government indicated that the proposed railway could be extended to the Port of Gwadar on the Arabian Sea.[112] As of February 2014, however, Chinese rail experts said the railway was unlikely to be built in the near term.[112]

Indian and Chinese rail authorities have on several occasions expressed interest in initiating a high-speed rail link that would link Kolkata with Kunming, China via Myanmar.[113][114] The rail link would use the under construction railway from Manipur, India to Myanmar and the Dali–Ruili railway under construction in western Yunnan Province.
