The Shanghai Metro (Chinese: 上海地铁; pinyin: Shànghǎi Dìtiě; Shanghainese: Zaon⁶he⁵ Di⁶thiq⁷) is a rapid transit system in Shanghai, operating urban and suburban transit services to 14 of its 16 municipal districts^[d] and to the neighboring township of Huaqiao, in Kunshan, Jiangsu Province.

Forming the vast majority of the broader, multi-operator Shanghai rail transit network, the Shanghai Metro system is the world's second longest metro system by route length after Beijing, totaling 837 kilometres (520 mi).^[5][c] and the second largest system by number of stations, with 508 stations across 20 lines.^[a][b] It also ranks first in the world by annual ridership, with 3.88 billion rides delivered in 2019.^[6] The last daily ridership record was set on 9 March 2024, at 13.39 million rides.^[2] Since the pandemic, ridership still routinely stands at over 10 million on an average workday, accounting for 73% of trips on public transport in the city.^[7][8]

Opening to the public in 1993^[9]: 19 with full-scale construction extending back to 1986, the Shanghai Metro is the third-oldest rapid transit system in mainland China, after the Beijing Subway and the Tianjin Metro. Though actual construction and inauguration of the Shanghai Metro succeeded its counterparts in Beijing and Tianjin, their initial planning would date back to the same period, during the late 50s and early 60s, before the impact of the Cultural Revolution.

The system saw its most rapid expansion during the years leading up to the 2010 World Expo, namely, between 2003 and 2010. Between 2007 and 2010, it was customary for new lines and extensions to open on an annual basis. The system is still expanding, with the most recent expansions opening in early 2024, and several new lines and extensions under construction.

The first proposal of a subway system for Shanghai dates back to the year 1950. Against the backdrop of the air raids of Shanghai by the retreating Nationalist forces in that year, a team of Soviet technical specialists visiting the city made a proposal to the Municipal Committee on Urban Planning and Design for a dual-purpose underground railway system, to be used for mass transit during peace times, and as shelter facility in times of war. It was later, in 1953, during confidential consultations held with Soviet urban planning specialists by Li Gancheng, the then-Deputy Chief and Party Secretary of the Municipal Construction Committee in Shanghai, that the initial concepts of a north-south line and an east-west line were pencilled on a map of the city, which would later become Line 1 and Line 2.^[10] Further consultations and public surveys on transit needs were held in 1959 by a Municipal Planning Committee for Underground Railway, in conjunction with the Municipal Public Utilities Management Bureau, and identified multiple alternative plans for a subway system.

In 1960, with a newly-formed a Bureau of Tunnel Engineering, the city undertook an experimental shield tunneling project in Tangqiao, Pudong, excavating a tunnel with a 4.2m-diameter shield for over 100 meters. Dubbed Project 60, this project was carried out in strict confidentiality.^[10] In August 1964, the Tunnel Engineering section of the Municipal Urban Construction Bureau completed the route selection phase for the north-south line (later Line 1), which was eventually to connect key locations in the downtown core, including the Shanghai Cultural Square, People's Square and the then Shanghai North railway station, with the rapidly industrializing and urbanizing northern districts of Zhabei and Baoshan, including the industrial zone in Pengpu, the worker's residential area in Zhangmiao, and the town of Wusong. It is ostensibly in this same period that, in 1965, another experimental project on underground tunnel and station construction was underway in a segment between Hengshan Park and Xiangyang Park, both in Xuhui. However, construction halted during the immediately subsequent Cultural Revolution period, and no systematic plan to build an underground railway system materialized.

The economic reforms of 1980s and the rapidly increasing demand for efficient urban public transit saw a swift resurrection of plans for a rapid rail transit system in Shanghai. In 1983, a jointly-published "Proposal on the Construction of a North-South Rapid Rail Transit Line" by the Municipal Planning Committee, the Municipal Construction Committee, in collaboration with the Municipal Bureaus of Urban Planning, of Public Infrastructure, of Railways and of Public Works, called for a rail transit line to be built which connects the city center with Minhang and Jinshan in the south-southwest, and with Wusong and Baoshan in the north-northeast, clearly echoing the initial north-south line concept of the 1950s-60s, though couched in this period in terms of the City's new master plan to "develop both the north and the south wings."^[11] Subsequently, in August 1985, a Project Planning Report submitted to the Municipal Planning Committee and the Municipal Committee on Urban and Rural Construction and Management by the Preparation Working Group on the North–South Rapid Rail Transit Line prioritizes the Xinlonghua-to-New railway station segment, and makes a conclusive case for the route of the previously-indeterminate middle segment of the line to be placed under Huaihai Road. Thus, the first stage of the first underground railway line, later Line 1, was determined.

Formal central government-level approval of both the construction of Line 1 and a long-term system-wide plan for the Shanghai Metro came in 1986. In that year, the State Council approved the Master City Plan of Shanghai (1983–2000), the first-ever such approval by the State Council in the history of Shanghai. Part of that Master Plan included a 40-year phased program that would eventually see the construction of 11 metro lines covering over 325 km by 2025.^[12] On August 14, 1986, the State Council approved the "Proposal Concerning Construction of Shanghai City Subway Line from Xinlonghua Station to Shanghai Railway Station,"^[13] clearing the pathway for the beginning of construction of Line 1.

The southern section of line 1 (four stations) opened on May 28, 1993. The full line (including middle and northern sections) eventually opened on April 10, 1995, and in the first year, it handled an average of 600,000 passengers daily.^[14] The first phase of line 2 was inaugurated in June 2000, which in 2010 linked Hongqiao International Airport (SHA) and Pudong International Airport (PVG). The 25 km Pearl line (line 3) opened for revenue service in 2001. Line 5 opened in 2003. Line 4 joined the network in January 2006 and became a circular line in 2007.

The Master Plan of Shanghai Metro-Region 1999–2020 was approved by the State Council of China on May 11, 2001.^[15] The plan had 17 lines in total, containing four intra-city-region express rail lines, eight urban metro lines, and five urban light-rail lines with a total length of about 780 kilometers. The total length of the planned MRT network in the central city will add up to 488 kilometers. In addition, Shanghai will strengthen the development of the suburban rail transport network so that it can link to and coordinate with state rail lines, metro lines, and light railways. One or two rail transport lines are planned between every new city and the central city.

In 2003 when the length was only 3 lines, 65 kilometers (with a further 5 lines already under construction), Shanghai was named host city for the World Expo 2010, plans were made to extend the length of the Metro to 400 kilometers by the time it opened in 2010.^[16] Thereby it completed the initial 40-year plan 15 years ahead of schedule. During Expo 2010 the metro system consisted of 11 lines, 407 km, and 277 stations.

In 2009 Shanghai announced it would have 21 lines operating by 2020 with lines extending further into the suburban areas. At the end of 2021 (expected), most of the lines of the plan were opened (with an exemption of line 20, Jiamin line, and Chongming line) leading to 19 lines (line 1-18 and Pujiang), 802 km, 516 stations.

On October 16, 2013, with the extension of line 11 into Kunshan in Jiangsu province (about 6.5 km), Shanghai Metro became the first rapid transit system in China to provide cross-provincial service and the second intercity metro after the Guangfo Metro.

The National Development and Reform Commission has approved the 2018-2023 construction plan for the city's Metro network. The construction of five new metro lines (and two commuter rail lines) and two extensions to opened lines are expected to take five to six years and are planned to start construction before 2023. After completion, there will be 27 metro and commuter rail lines covering 1,154 kilometers.

With the Shanghai Master Plan, 2017-2035 more emphasis was put on other rail transit modes. The plan calls for a comprehensive transportation system that consists of multimodel rail transit. Intercity lines (intercity railway, municipality railway, and express railway), urban lines (subway and light rail), and local lines (modern tramcar, rubber-tired transit system) in a length of more than 1,000 km each.^[17]

By 2035, public transportation will account for over 50% of all means of transportation, and 60% of rail transit stations in the inner areas of the main city will have 600m of land coverage. According to the NDRC, the Shanghai Metro network (including commuter rail) will cover 1,642 kilometers in total by 2030 and more than 2,000 kilometers by 2035.^[18]

Since 1993, the ridership of the entire network has grown as the new lines or sections come into operation. In 1995, the first year of operation, line 1 carried 62 million passengers (average daily passenger volume of 223,000).^[19] Ridership increased between 2011 and 2016 with 10% per annum, between 2017 and 2019 with 5%. The reduction in ridership in 2020 is due to Covid-19.^[20] Ridership recovered to close to pre-covid levels in 2021, with a ridership on December 31 of 13.014 million.

There are currently 19 lines in operation, with lines and services denoted numerically as well as by characteristic colors, which are used as a visual aid for better distinction on station signage and on the exterior of trains, in the form of a colored block or belt.

Most tracks in the Shanghai Metro system are served by a single service; thus "Line X" usually refers to both the physical line and its service. The only exception is the segment shared by lines 3 and 4, between Hongqiao Road station and Baoshan Road station, where both services use the same tracks and platforms.

The Shanghai Metro system is one of the fastest-growing metro systems in the world. Ambitious expansion plans call for 25 lines with over 1,000 km (620 mi) of length by 2025.^[49] By then, every location in the central area of Shanghai will be within 600 m (2,000 ft) of a subway station.^[50] Shanghai metro is connected with the metro system of Suzhou Rail Transit;^[51] the Suzhou Rail Transit line 11 connects Shanghai Metro line 11 with Suzhou Rail Transit line 3.^[52]

There are currently over 7,000 railcars in the Shanghai metro system. The train fleet reached 1,000 cars in 2007, 2,000 cars in 2012, and 3,000 cars in 2016, the 4,000th car was delivered on December 17, 2016, the 5,000th car was delivered on July 20, 2018.^[65] The 7,000th car was delivered on December 25, 2020.^[3]

Most lines currently use semi-automatic train operations (STO/GoA2). Starting and stopping are automated, but a driver operates the doors, drives the train if needed and handles emergencies. The exceptions being:

• Lines 2, 5 and 17: Driverless train operations (DTO/GoA3) train attendant operates the doors and drives the train in case of emergencies.
• Lines 10, 14, 15, 18 and Pujiang line: Unattended train operations (UTO/GoA4) starting and stopping, operation of doors are all fully automated without any on-train staff. With a total length of 169 km it is the world's 2nd largest fully automated metro system, after the Singapore MRT.^[66]

Most lines currently use 6 car sets, with the exceptions being:

• The Minhang Developing Zone branch of line 5, line 6 and Pujiang line, which uses 4 car sets.^[67]
• Most trains on line 8 use 7 car sets.^[67]
• Lines 1, 2 and 14 use 8 car sets.

On most lines the maximum operating speed is 80 km/h (50 mph), with the exceptions being:

• Lines 11 and 17 the maximum operating speed is 100 km/h (62 mph).
• Line 16 the maximum operating speed is 120 km/h (75 mph).

Pujiang line is the only line using cars with rubber tires running on concrete tracks.

All subway cars have air-conditioning. During summer of 2021 the subway's first and last carriages on Metro lines 3-5, 10-13, and 15-18 will be 2 degrees Celsius warmer than the other carriages, the air-conditioning is adjustable for different carriages on these lines. The measure aims to address the needs of some passengers who find the trains "too cold," especially the elderly and children.^[68]

Almost all stations have (full height) platform screen doors with sliding acrylic glass at the platform edge. Only half height doors called automatic platform gates^[69] are placed at most of the elevated sections and the section of line 2 from Songhong Road to Longyang Road. The train stops with its doors lined-up with the sliding doors on the platform edge and open when the train doors open, and are closed at other times.

During construction of the early lines conditions were reserved for the installation of platform screen doors but not installed, due to cost considerations and no domestic companies making them at the time. In the early 2000s, before the screen doors were installed, the annual suicide rate on the Shanghai subway system averaged about eight.^[70] In 2003 Shanghai Metro Operation Technology Development Co., Ltd. developed domestically platform screen doors with costs only 40% of imported platform screen doors (they cost over RMB6 million each to install).^[71] Shanghai Circus World, opened December 28, 2004, was the first station to have installed platform screen doors. To help cope with passenger handling, platform safety doors were built for line 4 onwards^[j] and a program for retrofitting older lines was put in place.^[72] The retrofitting on existing lines started in November 2005 with line 1 (first station was Xujiahui) whose core stations had doors by the end of 2006.^[73] Originally, platform screen doors were adopted to prevent cool or hot air from leaving the station to reduce electricity usage.^{[citation needed]}

Shanghai metro started building solar plants from 2013 and the process has been accelerated since 2019, with plans to build rooftop solar plants with a total electricity generation capacity of 30 to 50 megawatts between 2021 and 2025. In 2021 it owned through it subsidiary Shanghai Metro New Energy Co., Ltd. ten rooftop solar plants on depots and parking lots (Chuanyanghe, Zhibei, Jinqiao, Longyang Road, Sanlin, Fujin Road, Zhongchun Road, Beizhai Road, Chentai Road and Pujiang Town) generating an average annual power generation of about 23 million kwh.^[74] Annual electricity consumption of Shanghai Metro exceeds 2.5 billion kWh.

There is cellular phone network coverage across the network. In 2020, all stations provided 5G network coverage.^[75] Free WiFi is also provided.^[76] There are toilets for passengers in more than 90% metro stations in Shanghai.^[77] The system is 100% wheelchair accessible, with elevators at all stations.^[78]

Riders are subject to searches of their persons and belongings at all stations by security inspectors using metal detectors, X-ray machines. Items banned from public transportation such as "guns, ammunition, knives, explosives, flammable and radioactive materials, and toxic chemicals" are subject to confiscation.^[79]

Stations are equipped with closed-circuit television. Police use it to arrest pickpockets caught on CCTV, for example.^[80]

Smoking is strictly prohibited in the metro premises. Bicycles (including folding bikes) and pets (including cats, dogs etc.) are not allowed in stations. The use of skateboards, roller skates and other equipment is not allowed in stations and carriages.^[81]

Since April 1, 2020, there is a national ban on "Uncivilized Behavior" on China's Subways, which also includes conduct rules cracking down on bad subway etiquette, such as stepping on seats, lying down on a bench or floor and playing music or videos out loud. It also bans eating and drinking on subway cars nationwide, with exceptions for infants and people with certain medical conditions.^[82]

First AEDs (automatic external defibrillator) were installed at Metro stations in 2015, with all metro stations having AEDs at the end of 2021.^[83]

From February 14, 2022, the operations of line 11 in Kunshan have been suspended due to COVID-19 cases in Suzhou.^[84]

Plasma screens on the platforms show passengers when the next two trains are coming, along with advertisements and public service announcements. The subway cars contain LCD screens showing advertisements and on some lines, the next stop, while above-ground trains have LED screens showing the next stop. The LED screens are being phased in on line 1 and are also included in lines 7 and 9, two underground lines.

Station signs are in Simplified Chinese and English. There are recorded messages stating the next stop in Mandarin, English, and (on lines 16 and 17 only) Shanghainese,^[85][86] but the messages stating nearby attractions or shops for a given station (a form of paid advertising) are in Mandarin only. The metro operating company is resistant to expanding use of Shanghainese for announcing stops, on the basis that, on most lines, the majority of passengers can understand either Mandarin or English.^[87]

The Metro authority has tested a new systematic numbering system for stations on line 10, but did not extend it to other lines.^[88]

On December 31, 2009, Shanghai launched a website Archived October 25, 2018, at the Wayback Machine displaying real-time comprehensive passenger flow information, each station and line is displayed as either green (normal operation), yellow (crowded), and red (suspended/not in operation).

Short turn service patterns exist on all lines except line 16. Partial services serve only a (usually busier) sub-segment of the entire physical line.^{[29][30][31][33][35][36][37][38][39][40][41][42][43][45]}

Line 11, one of the three branch lines of the metro system, operates a different short turn service pattern. Trains traveling to and from the branch line terminate at Huaqiao Station and Sanlin respectively. Hence, a passenger who wants to travel from the terminus of the branch to Disney Resort, the eastern terminus of the line, must change trains.^[40]

Line 16, unlike the rest of the system, is built with passing loops and operates express and rapid services. The service was postponed on January 30, 2014, due to lack of available trains, but resumed on March 21, 2016.^[89][90][91]

The operating hours for most Shanghai metro stations starts between 5:00 to 6:00 in the morning and ends between 22:30 to 23:00 CST. The current timetable is available on the Shanghai metro website.

The interval of trains during peak hours differ between 1 minutes and 50 seconds on line 9 and 6 minutes on line 18. Lines in the inner sections have train intervals under three minutes during morning peak hours and under 3 minutes and 45 seconds during evening peak hour. The more suburban outer sections, outside peak hours train intervals are longer.

On lines in the city center on Fridays and Saturdays, operating hours are extended by an additional hour. From April 1, 2017, the operating hours of lines 1, 2, and 7-10 were extended by an hour after the regular last train on each Friday, Saturday and the last working days before Chinese Public Holidays.^[92] Since July 1, 2017, this was extended such that lines 1-4 and 5-13. By the end of 2018, all the stations in the city center extended their operating hours after midnight on Fridays and Saturdays. Since September 30, 2020, extended operation was resumed on lines 1, 2, 9 and 10.^[93] Since April 30, 2021, also extended weekend operation of lines 7 and 13 was resumed.^[94]

On Sunday to Thursday, there are two trains on both line 2 and 10 taking passengers from Hongqiao railway station and airport after normal operation time and only stop at selected stations.

Like many other metro systems in the world, Shanghai Metro uses a distance-based fare system. The system uses a "one-ticket network", which means that interchanging is possible between all interchange stations, given that the transfer staying within the Shanghai Metro system, without the purchase of another ticket where available, excluding some stations where transferring to another line at said station requires leaving the Fare Zone which mandates a Single-Journey Ticket be used before entering that of another line, requiring the purchase of another Single-Journey Ticket (Shanghai Public Transport Cards are exempt as they are not consumed upon exit). The Shanghai Public Transport Card, which allows access to most public transport in Shanghai under one card, is another form of payment.

All stations are equipped with Shanghai public transport card self-service recharge machines, some of which support card sales and card refund operations. Passengers can also choose to purchase public transport cards to travel. Since 2005 automatic ticket vending machine, which accepted banknotes, appeared in Shanghai Metro stations.^[95] Automatic ticket vending machines are divided into "coins only" and "coins and banknotes are collected", the coin only machine collects 1 yuan and 0.5 yuan, and the coins and banknotes all accept 5, 10, 20, and 50 yuan banknotes and 1 and, 0.5 yuan coins. Vending machines will provide change.

One or two children not taller than 1.3 meters (inclusive) are exempted from paying a fare in accompany of another passenger. In cases of more than two, the passenger should buy tickets. A preschool child, unattended by an adult, is not allowed to take the train alone.^[96]

A pass for unlimited travel within the metro system for either 24 or 72 hours is offered. This pass is not available through vending machines, but has to be purchased at Service Centers at metro stations.^[97]

• A one-day pass priced at 18 yuan. This pass was introduced on April 24, 2010, for the Expo 2010 held in Shanghai.
• A three-day pass priced at 45 yuan. This pass was available since March 8, 2012.
• A Maglev single trip ticket and metro ticket priced at 55 yuan. This pass allows for a ride on the Shanghai Maglev Train and unlimited travel within the metro system for 24 hours. A Maglev round trip and metro ticket is priced at 85 yuan.

• The base fare is 3 yuan (RMB) for journeys under 6 km, then 1 yuan for each additional 10 km. As of December 2017, the highest fare is 15 yuan (travel between Oriental Land to Dishui Lake, the farthest distance at present).^[98] This fare scheme has not changed since September 15, 2005.^[99]

• Shortest route calculated as multiple route available between any entry-exit stations.
• Travel time limit is 4 hour. Additional lowest single journey fare (3 yuan) is required if time limit is exceeded.
• For journeys exclusively from Xinzhuang Station to People's Square Station, the fare is 4 yuan, though the distance between People's Square Station and Xinzhuang Station is about 17.8 km (11.1 mi).

Only passengers with unused tickets at the station on the day can refund tickets at the service center. Refunds can also be processed in the event of a train failure for more than 15 minutes, and the apology letter can be downloaded on the official website, WeChat public account and Metropolis app.

Single-Journey tickets can be purchased from ticket vending machines, and at some stations, at a ticket window. Single-ride tickets are embedded with RFID contactless chips. When entering the system riders tap the ticket against a scanner above the turnstile, and when they exit they insert the ticket into a slot where it is stored and recycled. This ticket does not facilitate transfers at a virtual interchange station. Passengers would have to purchase a new ticket when reentering the fare gate.^[100]

In addition to a single-ride ticket, the fare can be paid using a Shanghai public transport card. Transportation card of other cities that utilizes China T-Union can also be used in Shanghai Metro. This RFID-embedded card can be purchased at selected banks, convenience stores and metro stations with a 20-yuan deposit. This card can be loaded at ticket booths, Service Centers at the metro stations as well as many small convenience stores and banks throughout the city. The Shanghai Public Transportation Card can also be used to pay for other forms of transportation, such as taxi or bus. Refunds can be obtained at selected stations.^[s][101]

Discounts for SPTC holders:

• Cumulative discount: Users of the Shanghai public transport card or QR codes get a 10% discount for the rest of the calendar month after paying 70 yuan in taking metro, The discount is applied only for journeys after the payment; it is not retroactively applied to previous journeys.^[102]
• Virtual-transportation discount: Transfers at virtual interchange stations the fare will be calculated continuously. This discount is also applicable for T-Union transportation cards of other cities and Shanghai Public Transportation QR code.^[102]
• Combined ride discount: Users of the Shanghai public transport card and QR codes get a 1 yuan discount when transferring to the metro within 120 minutes. (The 10% monthly discount may be applied after the transfer discount.) This discount also applies for a bus to Metro and bus to bus transfers and can accumulate over multiple transfers. Depending on the time spent at the destination the discount will be applied at the start of the return trip as well, making the cost of a round-trip 11 yuan instead of the 16 yuan that would normally be charged without the card.^[102]

Passengers can also pay their Shanghai Metro fares using a mobile phone app, Daduhui (Metro Metropolis) since January 2018. The app requires one to scan a QR code when entering the fare gate at the origin station and again when exiting at the destination station. The fare is then deducted.^[103] The system supports Alipay, WeChat Pay and Union Pay, three of the most commonly used mobile payment methods in China.^[16]

The Shanghai Public Transportation QR Code, which is accessible through Alipay, WeChat and other applications, has been accepted on the Shanghai Metro since 2022. The usage of the Shanghai Public Transportation QR Code does not require bluetooth. Furthermore, users of the aforementioned QR Code are entitled to the same fare discounts as users of a Shanghai Public Transportation Card.

The official reported daily fare evasion rate accounts for about 0.16% of the total passenger flow.^[104] In the Shanghai Metro fare evasion will result in a fine of 6 times the fare.^[105]

Shanghai Metro have been cooperating with police to crack down on subway fare evasion. In 2012, the Shanghai Metro has reported 202,457 counts fare evasion, and an additional 472,898 yuan of adjusted fare was collected.^[106] Since June 3, 2013, the subway operator announced that all evaders will be recorded in the personal credit information system, which may lead to obstacles in loan applications and job hunting in the future.^[107] However, in actual implementation, the subway law enforcement officers only took the above measures for those who refused to make up the fare; and in some stations where fare evasion often occurred, the ticket gates were changed from the original three-bar type to gate type gates.^[108][109]

In 1999, Shanghai Electric and Alstom Metropolis signed an agreement to invest 28 million US dollars to establish Shanghai Alstom Transportation Equipment Co., Ltd., and introduce a rail transit train production line in Minhang, which would be able to assemble 300 trains annually. Shanghai Alstom only had the national license to produce C-class cars from its establishment and no license to produce A-class cars. At that time, the municipal government stipulated that Shanghai would purchase 300 C cars produced by the new company on lines 5, 6, and 8 of the future rail transit construction. The two parties reached an agreement on the purchase of 300 cars at that time. For this reason, the Transportation Research Institute had to "reduce" the predicted passenger flow to accommodate the C-class railcars, allowing for a reduction of the station's civil construction scope for the smaller trains. In the construction of lines 5, 6, and 8, the railcars were not supplied by the completion of the tender, but by a signed agreement for the railcars after "internal consultation and coordination" between Shentong Group and Shanghai Alstom, a violation of Articles 3 and 4 of the Law of the People's Republic of China on Tendering and Bidding.

The person in charge of the passenger flow forecasting project of line 8 confirmed that the passenger flow forecast report of line 8 was not completed until 2005 after continuous revision. However, in 2003 an agreement was signed for line 8 to supply 168 C-class vehicles, i.e., Shentong Group signed an agreement with Shanghai Alstom two years before the release of the forecast report, and decided to use the C-class car. At that time, it was predicted that the forecast passenger flow of line 8 would be about 500,000 passengers per day during the three years from 2007 to 2010. The operator used as initial forecast passenger flow of only 200,000 passengers per day. line 8 was extremely congested upon opening, even leading to physical conflicts between passengers. In 2010, to deal with the overcrowding Shanghai Metro hired passenger pushers to assist commuters boarding line 8 trains.^[110] Today, line 8 carries up to over 1 million passengers a day.

The estimated passenger flow of line 6 was more than 105,000. However, the highest passenger flow in the first few days of opening reached 150,000.^[111] With a headway of 13.5 minutes at opening and only four carriages, during peak hours people had to wait 45 minutes to get a ride. The relevant departments did not conduct a comprehensive survey of the residents around the proposed line to estimate passenger flow but instead household registration data was used which excludes migrant populations.^[112]

In June 2012, Shanghai Metro published a post on Weibo asking women to wear more clothing in public. The post argued that it was not surprising for women to be harassed in the subway if they are wearing revealing clothing and called on women to cherish themselves. This post attracted backlash from women's rights advocates and feminists who called the post misogynistic.^[113]

• March 24, 2004: An evening crash at the turnaround line north of Tonghe Xincun station occurred during testing of the north extension of the line 1 (which opened on December 28, 2004), train No. 122 had a side collision with No. 102 train, resulting in train No. 102 being damaged beyond repair.

• December 22, 2009, at 5:58 a.m., an electrical fault in the tunnel between South Shaanxi Road station and People's Square station caused a few trains to stall. The tripping failure of the power supply catenary was caused by the top of the tunnel falling down and causing a short circuit. The segment between Hengshan Road and Hanzhong Road was suspended.^[115] At 6:54 a.m., while the track was under repair, a low-speed collision occurred between two trains on line 1 at Shanghai railway station. As train No. 150 went to the Shanghai railway station's turnaround the signalling system sent a speed code of 65 km/h instead of 20 km/h, resulting in insufficient braking distance as the distance between train No. 150 and No. 117 was only 118 meters when the signal system sent a code of a speed of 0 km/h. As train No. 150 increased speed from 60.5 km/h to 62 km/h, the train driver commenced emergency braking, preventing a more serious collision. The train collided at a speed of 17 km/h with the side of the rear of train No. 117 entering the turnaround track from the down platform in the reverse direction. Nobody was injured, but the front of the train No. 150 and the middle and rear of train No. 117 which was badly damaged. There were no passengers aboard train No. 117. Service resumed at 11:48 a.m.^[116] Some passengers on train No. 150 were in the train until 11 a.m. The crashes affected millions of morning commuters and occurred during Dongzhi Festival, when people visit cemeteries to pay tribute to their departed ancestors.^[117]

Sun's mother sued Shanghai Metro for 1.18 million yuan. The man was found to be carrying 0.29 grams of heroin, and the drug was detected in his blood. As platform screen door had repeatedly caught people, officials said safety switches will be installed on the inside of the screen doors. If someone touches the safety switch, the train will be suspended. A laser detection device was under development to reduce the chance of similar incidents.^[122]
• July 24, 2007, at 2:41 p.m. A passenger entered a northbound line 1 train at Xujiahui station when the buzzer sounded.
