Guangshen railway orGuangzhou–Shenzhen railway (Chinese:广深铁路 or 广深线), historically known as theChinese section of the Kowloon–Canton railway (Chinese:广九铁路华段) in 1911–1949, is a railway inGuangdong province in thePeople's Republic of China, betweenGuangzhou andShenzhen. It is operated byGuangshen Railway Co., Ltd., a publicly traded company.

With a length of 147 kilometres (91 mi), it was the first railway in the People's Republic of China to reach the speed of 220 km/h (137 mph) in some sections, though it is limited to about 180 km/h (112 mph) during commercial operation. Now it has four tracks betweenGuangzhou East andShenzhen railway station. Line 1 and 2 areup-direction anddown-direction 200 km/h (124 mph) (currently restricted to 180 km/h (112 mph) in operation) passenger lines forCRHEMU respectively, and Lines 3 and 4 are up-direction and down-direction 160 km/h (99 mph) (currently restricted to 140 km/h (87 mph) in operation) mixed passenger and freight line respectively. In order to reduce the interference topassenger trains in the daytime from lower-speedfreight trains, most freight trains will be scheduled to run at night.

Guangshen railway connects with several other important railways to different directions. It linksJingguang railway andGuangmao railway in Guangzhou,Jingjiu railway in Dongguan (with which shares two regular speed track), and theEast Rail line to Hong Kong at the southern end of the railway. Besides, there are some branch lines along Guangshen Railway, such asPingyan railway toYantian Port,Pingnan railway toShenzhen West railway station and also the line toHuangbu Port.

Before the manifestation of COVID-19 pandemic in January 2020, traditional "Z-class" border-crossing services via the whole or part of the Guangshen Railway, serving Hong Kong and mainland destinations includingChangping, Guangzhou East,Foshan andZhaoqing, as well as toBeijing West and Shanghai, were available. However, the above-mentioned cross-border services were suspended since the on set of COVID-19 pandemic.^[1]

Starting 15 January 2023, train services between Hong Kong West Kowloon Railway Station and Guangzhou East Railway Station are available,^[2] at which Guangzhou-Shenzhen Railway is part of the route.

The idea of constructing a railway linkingCanton (nowGuangzhou) andKowloon inHong Kong, a Britishcrown colony germinated in the lateQing dynasty. In 1899,Britain and the Qing government agreed to construct theKCR British Section, but Britain postponed the construction as Britain was busy at theSecond Boer War in Africa. In 1907, Qing government andBritain formally signed an agreement in Peking on issuing a £100-millionbond as part of loan for the construction of the Chinese section of the Kowloon–Canton railway. In July 1907, construction of the British Section of the KCR began. The construction of Chinese section was delayed and only started in 1909. Under the loan contract, China needed to employ the British engineers for the construction of Chinese section, but China still employed famous Chinese railway engineer,Zhan Tianyou, as a consultant. On 8 October 1911, the Chinese section of KCR with total length of 142.77 km (88.71 mi) was opened^[3] together with the commencement ofthrough train service between Kowloon and Guangzhou which was started to operate at the same time. The northern end of railway at that time was located in Dashatou (大沙頭), Guangzhou, which was demolished in 1951^{[citation needed]}.

After the establishment of People's Republic of China in October 1949, the 'Chinese section of the Canton–Kowloon railway' was renamed 'Guangshen railway', and repairs were made to sections of the railroad damaged during the war. In 1967, railway department carried out a comprehensive maintenance on Guangshen railway to improve the transport capacity. Beginning in the 1980s economic reform policies of China, the establishment of ShenzhenSpecial Economic Zone and rapid economic development in thePearl River Delta region has brought large volume of imported goods and increased passenger demand to the railway. Therefore, the second line of Guangshen Railway was constructed during 1984 to 1987 in order to meet the huge demand. Simultaneously Guangshen Railway Company (the predecessor ofGuangshen Railway Company), which was directly subordinated to the Guangzhou Railway Bureau (nowGuangzhou Railway Group), was established. This company was in charge of the construction projects and operational management of Guangshen Railway. In 1987, Guangshen railway became the first double-track railway inGuangdong province.

Guangshen railway is the first place in China to carry out successfully speed-up on the existing railroad. At the beginning of the 1990s, Guangzhou Railway Bureau and theMinistry of Railways carried out the pre-feasibility research about raising the maximum speed of passenger trains to 160 km/h (99 mph). At 28 December 1991, the construction of the third line of Guangshen railway, and the speed-up improvement works of original double tracks started. In October 1994, the maximum speed of a train reached 174 km/h (108 mph) during the test. The first sub-high speed (160 km/h (99 mph))^[4] passenger train in China started commercial operation at 22 December 1994, operating between Guangzhou and Shenzhen.

In 1998^[4] theelectrification of two sub-high speed lines of Guangshen railway was finished. After the improvement the 200 km/h (124 mph) high speed trains are allowed to run on the existing sub-high speed railroad. A Swedish-builtX 2000tilting train called 'Xinshisu' began to serve intercity train service between Guangzhou and Shenzhen, as well as thethrough train to Hong Kong. The train are 165m long, consisting of apower car, five passenger cars, and a trailing car. The non-power cars can have a pitch of up to 8 degrees. They are noted for being very quiet (less than 65dBA) even at 200 km/h (124 mph). Such Swedish X 2000 trains allowed the line to reach 200 km/h (124 mph) and 220 km/h (137 mph)^[4] in some sections^[4] of the Guangshen line.

Starting 21 October 2001, the "As-frequent-as-buses" Train Project was fully roll out^[5]: p.5 using 8 sets of domestic made"Blue Arrow" trains,^[5]: p.2 which were high-speed (capable to reach a speed of 210 km/h)^[5]: p.2 electrical trains for express service between Guangzhou and Shenzhen.

Construction of the fourth track was commenced at 31 December 2005, and was finished at 18 April 2007 in time for theSixth Speed-Up Campaign. Since then Guangshen railway has been the first four-track railway inmainland China and it allows passenger trains and freight trains to run on separate lines.

8-carCRH1A highspeedEMUs have been introduced since year 2007 for the intercity train service between Guangzhou and Shenzhen. There were 100 pairs of trains operated daily. The fastest journey time was 52 minutes betweenGuangzhou East andShenzhen with no stop in-between. Train numbers D7002 and D7008 had been used for such direct service.

Implementation of "stop-at-all-stations" operating model started since 1 May 2009^[6]: p.12 at which intermediate stations includesDongguan (located inChangping at that time),Shilong andZhangmutou.^[7]: p.38

Non-stop trains serving between Guangzhou East and Shenzhen re-emerges since the early 2020s^[8] at which "C8" prefix train numbers^[8] are introduced for such service.

Regularly operating service between Guangzhou and Shenzhen uses 8-carCRH1AEMU orCRH6AEMU. Currently train numbers with prefix "C" are in use.

According toOfficial customer portal of China Railway^{[Note 1]} as at October 2024^[10][11] showing all train trips between Guangzhou city and Shenzhen city, train numbers (C800x-C801x) are assigned for non-stop express trips running betweenGuangzhou East railway station andShenzhen railway station.

For "C" prefix trains numbered by 4 numerical digits (7xxx or 80xx) servingShenzhen railway station and Guangzhou city, a majority of trains serveGuangzhou East railway station at Guangzhou side, and within the Guangshen line a few number of trains serveGuangzhou railway station, mostly in a manner as an intermediate stopping before terminating atGuangzhou Baiyun railway station^[12] which is located at short distance beyond the Guangshen line.

Temporally added trips for the Guangzhou-Dongguan-Shenzhen service may be numbered with prefix "Z",^{[Note 2][13][14][15]} "C" or "D", usingShenzhen East railway station^{[14][16][17][18][19]}orShenzhen railway station as the terminal station.

In addition to CRH EMUs running temporally added intercity trips typically numbered C9xxx, it is possible thatCR200J "Fuxing" trains are deployed to the temporally added trips (with prefix "D" or "C") since the allocation of 4 sets^[20]: p.14 of such type of "Fuxing" train to Guangshen Railway Company Limited (GSRC) at the time of year 2019^[20]: p.14 and thereafter.

The emergence of "D-class" trip using CR200J trains inShenzhen railway station begins in December 2019 serving regular long-distance D727, D728 trains^[21] forBeijing West^[20]: p.14 while this service actually runs mainly along the Beijing-Kowloon railway^{[Note 3]} which starts its multiplexes with Guangshen line in Dongguan City, meaning that the initial manifestation of CR200J trains along Guangshen line was just confined within a limited distance.

For the use of CR200J trains travelling longer distance of GuangShen line for demand-relief purpose, one noteworthy example is, to start with, an internet media reported that a temporally added service was available on 29 and 30 September and 2, 3, 5, and 6 October 2023,^[22] mentioning a pair of train service numbered D7495, D7496^[22] although that was a cross-line traffic betweenChangsha railway station andShenzhen East railway station for demand relief.

Shorter "intercity" service betweenShenzhen East railway station andGuangzhou East railway station may occur in a rare, temporally^{[Note 4]} manner while not on a regular basis. For the example in relation to the above-mentioned D7496^[22] service in year 2023, to start with, Guangzhou Railway Group maintains several Sina Weibo accounts officially where latest information about status of available tickets up-to-date, in particular for the days within peak demand period, may be posted. Previous posts in the Guangzhou Railway Group's official Weibo channels^{[Note 5]} show that service betweenShenzhen East railway station andGuangzhou East railway station was provided^[16][17] with available ticket on-sale among at least some, if not all, of the days that the above-mentioned D7495, D7496 trips were in service in year 2023.

Examples of temporally added "D-class" service between Guangzhou city and Shenzhen city during peak-demand holidays, at which written notice has been announced via the Chinese language page^[9] ofOfficial customer portal of China Railway beforehand, include the added service during "Spring Festival Travel Rush" (or named as "chunyun") in year 2024 numbered D9785-D9786^[18] serving betweenShenzhen East railway station andGuangzhou East railway station, and D9791-D9796^[23] serving betweenGuangzhou East railway station andShenzhen railway station.

During the holiday week of October 2024, there exists a pair of trains serving betweenGuangzhou East railway station andShenzhen railway station, using train set composed by both second class seat coaches and sleeper berth configuration coaches,^[24][25] with train numbers C99^[24] for southbound and C100^[25] for northbound services of peak demand days of October 2024 according to the timetable as shown at the China Railway's official 12306 website.^[10][11]

As mentioned in the Stations list in the "Stations" section in above, a few number of departures, using CRH trains, provide service toGuangzhou railway station. Starting year 2024,^[12] the coverage of above-mentioned service is further extended toGuangzhou Baiyun Railway Station as the terminal station, located some 5 kilometres distance^[30] beyond the Guang-shen line.

Starting 20 June 2022,^[31] service between Guangzhou East station andShenzhen North station is available.

Service extension to coverGuangzhou Baiyun railway station andFutian railway station in Shenzhen starts from 15 June 2024,^[32] in addition to the existing trains serving betweenGuangzhou East andFutian stations that already exist during June 2024.^[32]

These services use Guangzhou–Shenzhen railway as part of the route.

This service uses Guangzhou–Shenzhen railway and Ganzhou-Shenzhen High-speed railway toShenzhen North direction and provides service betweenGuangzhou East railway station andHong Kong West Kowloon Railway Station.

For traffic heading to other cities, there are services of EMUs using Guangzhou–Shenzhen railway as part of the route.

The completion of upgrading work in year 2020 makes the whole Guangshen line to be compatible withCTCS-2,^[33] as a result more EMUs from nationwide railway network can enter Guangshen line, and useShenzhen railway station,^[33][34]Guangzhou East railway station orGuangzhou railway station as terminal station.^[33] Thus, more cross-line traffic and also more variety of types of EMUs becomes available along the Guangzhou–Shenzhen railway.

On the otherhand, the construction of the Guangzhou-Zhanjiang High-speed Railway^[35] results in a disruption of some of the cross-line traffic, at which starting from 11 October 2023^[35] trains of China Railway running at or running for Foshan city will not enter to nor leave from theGuangzhou Railway Station.

Cross-line traffic servingChaoshan railway station is available daily, at bothGuangzhou East railway station, orShenzhen railway station near the Luohu border with Hong Kong.^[36] Some of those trains serveShantou also.

Starting 11 October 2023, train service betweenShenzhen railway station andChaoshan railway station is introduced.^[36][37]

Since December 2023, service running by G-prefix train trips betweenShenzhen railway station andShantou South railway station become available.^[38]

Starting 15 June 2024,^[39] service betweenShantou railway station andShenzhen railway station, near the Luohu border with Hong Kong, become available; and these C-prefix train number trips^[39] or D-prefix train number trips^[40] are operating daily in a regular basis.

Daily trains are offered betweenGuangzhou East Railway Station andChaoshan Railway Station, a few of them will continue toShantou Railway Station; in addition, starting from 1 July 2018, one departure serving the Guangzhou East to Chaoshan service will continue to Xiamen.

Since not later than 26 June 2021, more EMU trains are available for service between Xiamen (or Xiamen North Station) and Guangzhou city, at which two of them (using Xiamen North Station at the time of writing in June 2023) will continue to Nanning East Station.^[41][42] CRH2A EMU trains are in use for service between Xiamen North and Nanning.^[42] However, with effective from 11 October 2023 the above-mentioned trains, in particular those formerly serving between Fujian and Guangxi province via Guangzhou, are shorten to serve only between Fujian province and Guangzhou city.

Starting January 2024, service using CRH380A EMU running betweenGuangzhou East railway station andLongyan railway station becomes available.^[43]

Starting 11 October 2022, a pair of EMU train service betweenGuangzhou East railway station andHangzhou East railway station numbered D3121/4 and D3122/3 with a stop atShenzhen North railway station^[44] becomes available that CRH1E trains are in use.^[45][46]

Train departures are available between Guangzhou East station andGanzhou West railway station.

Between 15 January 2022^[47] to 9 January 2024,^[48] a pair of departures is available using CRH380A^[47] EMU trains, at which train G2775/G2778 departs from Guangzhou East station exists, and train G2777/G2776 departs from Ganzhou West station, as at June 2023 this service servesDongguan railway station as well; in addition, another pair for the Guangzhou East to Ganzhou West service was added since 11 October 2022, with train number D1695/D1698 and D1697/D1696,^[49] at which CRH1E-250 train is in use as at June 2023.

Starting from 10 January 2024, the above-mentioned service was suspended,^[50] and the newly added service for cross-line traffic between Guangzhou East station andGanzhou West railway station heading toJiangXi Province direction takesGuangzhou–Shanwei HSR toGanzhou–Shenzhen HSR^[51] instead thus the new service no longer servesDongguan railway station.

A disruption of this cross-line traffic, starting 11 October 2023, occurs because of the route adjustment of Guangzhou-Sanshui section of theGuangzhou-Maoming railway to facilitate the construction of the Guangzhou-Zhanjiang High-speed Railway.^[35]

Starting 10 July 2019^[52] to 10 October 2023, there was a daily service between Shenzhen Railway Station andHuaiji Railway Station onGuiyang-Guangzhou HSR, which is the first^[52] utilizing the whole Guangzhou-Shenzhen line in full as part of the route; starting 1 July 2020^[53][54] to 10 October 2023, daily service between Shenzhen Railway Station and Foshan West Railway Station was available; however, according to the new railway timetable effective from 11 October 2023, these direct train services no longer exist.

China Railway Nanning Group's^[56] EMU trains running on the whole Guangzhou-Shenzhen line used to be exist that, since not later than year 2023^[56] such EMU train service was previously available betweenShenzhen railway station (the one in Luohu district near the Hong Kong border) and Liuzhou^[56] via Guangzhou, at which this pair of service was numbered D3665 (southbound) and D3666 (northbound); however, with effective from 11 October 2023, train number D3665/D3666 no longer serves Shenzhen and Dongguan, and this pair of train serves Zhuhai^[55] and Zhongshan^[57] instead.
