WENZHOU HIGH-SPEED TRAIN CRASH

Wenzhou train crash
In late July 2011, two high speed trains collided, killing 40 people and injuring 177 in Wenzhou, near Shanghai, in Zhejiang Province in eastern China. The accident occurred when one high-speed train rear-ended another that was traveling at a low speed on an elevated track on a concrete bridge about 15 meters above farms and fields. It was the first derailment on China's high-speed rail network since the country launched its bullet trains in 2007 with a top speed of 155 miles per hour, the China Daily reported.

AP reported, “A bullet train crashed into another high-speed train... causing four carriages to fall off a viaduct. The first train was traveling south from the Zhejiang provincial capital of Hangzhou when it lost power in the lightning strike and was hit from behind by the second train in Wenzhou city at 8:27 p.m. The second train had left Beijing and both trains were destined for Fuzhou in eastern Fujian province...The Ministry of Railways said in a statement that the first four carriages of the moving train and the last two carriages of the stalled train derailed.

The dead included two schoolgirls, an Italian tourist and a pregnant woman who was killed with four family members, according to accounts in the Chinese press. “A preliminary investigation by the Zhejiang provincial government showed that four coaches of the moving train fell off the viaduct, Xinhua said. The cars plunged about 65 to 100 feet from the elevated section of track, it said. Photos taken at the scene showed one badly damaged car lying on its side by the viaduct and another car leaning against the viaduct after landing on its end.” [Ibid]

The Wenzhou crash was a heavy blow for the showcase high-speed railway programme and has invigorated public criticism over the costs and speed with which it has been rolled out. The trains involved are "D" trains -- first-generation bullet trains with an average speed of about 95 miles per hour and not as fast as the new Beijing-Shanghai line. High-speed rail has an excellent safety record elsewhere, especially in Japan, which has never had a fatality.

The Economist reported: After a deadly high-speed train crash in Zhejiang province in July, the authorities sent bulldozers to bury the wreckage. The crash was an embarrassment; a reminder that China’s state-directed rush to modernise has involved cut corners, shoddy safety standards and a staggering amount of corruption. That contradicted the official storyline, in which China has become the world’s second-largest economy thanks to the Communist Party’s wise guidance. Rather than grapple with awkward counter-evidence, the party tried to bury it.

Rescue of Two-Year Girl After the Rescue for Wenzhou Train Crash was Called Off

The Wenzhou city government said more than 1,000 people participated in the rescue operation. Xinhua quoted an unidentified witness as saying, "Rescuers have dragged many passengers out of the coach that fell on the ground." About 1,500 passengers were taken to a middle school, and more than 500 residents had given blood by 9 a.m. Sunday after appeals from the local blood bank, which said many of the injured needed transfusions, CCTV reported. [Source: AP, July 23, 2011]

Some Netizens watching video images and reading reports from the scene said it appeared authorities were burying the rail cars and had abandoned the search for survivors about six hours after the accident. Chinese President Hu Jintao and Premier Wen Jiabao called for an all-out effort to rescue passengers still trapped in the wreckage the morning after the collision several hours after China Central Television said the search-and-rescue operation had ended.

A two-year-old girl Xiang Weiyi was discovered alive in the wreckage and rescued 21 hours after the train crash and 14 hours after the search and rescue had officially ended. This touched off a deluge of criticism over what was seen as a blatant disregard for human life. Microbloggers asked whether her parents and others could have been saved had the rescue effort not been called off.

According to the China Daily the girl was pulled from the wreckage after a local police chief iniste the carriage be checked gain before it was pushed off the elevated track. Wang Yongping, a rail ministry spokesman, said at a July 24 news conference the girl’s survival was an example of "the miracle of life." He was derided by many in the online community. The spokesman was removed from his job in August and posted to Poland in a diplomatic role. [Source: Bloomberg News, September 18, 2011]

Cause of the Wenzhou High-Speed Train Crash

In September 2011, the Caijing financial magazine reported that an investigation into a deadly bullet train crash found that faulty signal systems and mismanagement were mainly to blame, though the accident was triggered by a lightning strike. The lightning strike caused one bullet train to stall and a sensor failure allowed a second train to keep moving on the same track and slam into it. Caijing cited one of the experts participating in the inquiry, Wei Zhen, a professor at the Hefei University of Technology. [Source: Associated Press, September 16, 2011]

The Daily News newspaper cited experts warning that the faulty signal systems are still in use at dozens of stations along high-speed rail lines. Reiterating earlier reported findings, it said the crash occurred because a signal that should have turned red when lightning stalled the first train stayed green. Railway staff also failed to notice something was wrong. The Beijing National Railway Research & Design Institute of Signals and Communications Co, which made the signal, has publicly apologised after the crash.

Chinese railway officials have blamed “serious design flaws” in railroad signaling equipment for the high-speed train crash in eastern China that, Xinhua, the official news agency, reported in July. After it was struck by lightning, the signaling device at the Wenzhou South railway station malfunctioned and failed to turn from green to red, An Lusheng, chief of the Shanghai Railway Bureau, told the news agency. He also said workers on duty were inadequately trained and failed to notice the malfunction. This revelation came after six days of silence by the government about why the trains collided. Its initial explanation was terse and vague: equipment failure due to a lightning strike. [Source: Sharon Lafraniere New York Times July 28, 2011]

Mr. An, faulted the quality of equipment and personnel, as well as on-site controls, Xinhua reported. He described safeguards as “still quite weak.” He had been transferred to the Shanghai job only days ago. His predecessor and two other railway officials were fired immediately after the wreck. Mr. An said the malfunctioning signal was designed by a Beijing institute. The Beijing National Railway Research and Design Institute of Signals and Communication apologized Thursday to victims on its Web site, saying it would “shoulder responsibility.” [Ibid]

He Jinliang, director of the China Standardization Association of Lightning Protection Technology, said in an interview that proper equipment would have averted the tragedy. While it might not be cost-effective to make rail equipment “100 percent lightning-proof,” he said, “you can definitely prevent this kind of serious accident.” [Ibid]

Japanese Experts Analysis of the Wenzhou Train Crash

Japanese experts said that the moving train was a CRH2 model, a Chinese copy of Japanese Kawasaki Heavy Industries' Hayate Shinkansen (bullet train), which operates on the Tohoku line in Japan. The train that was rear ended was a CRH1, based on technology from Canada’s Bombadier Inc.

Japan's Kyodo news agency reported this week that this model's maximum speed was set at between 200km/h and 275km/h to ensure safety but China began commercial operations at up to 350km/h on some routes. After learning this, Kawasaki Heavy said it had secured a written pledge from China that the Japanese company "would not be held responsible" if an accident was caused by speeding. An anonymous source at Kawasaki told Kyodo that company had long been concerned about the Chinese approach of prioritizing speed at the expense of safety.”

Japanese bullet trains have been equipped with automatic train control (ATC) system since they were introduced in 1964. ATC devices on bullet trains cause trains to automatically brake if they approach too close to one another. Rail safety expert Seiji Abe, of Kansai University, says that if China had implemented the ATC system used across Japan, the rearmost train would have been stopped automatically. He says the ATC system also includes lightning protection, which it appears China has also neglected. Professor Abe, who has worked as a rail crash investigator, says he doubts that Japanese rail companies will suffer any blow to their reputation because it is clear these trains are at best a copy, and probably one that does not include the necessary safety features.

Initial Government Response to the Wenzhou High-Speed Train Crash

The Railways Ministry initially responded to the Wenzhou train crash by stonewalling. State television, whose blinkered coverage of rescued babies only belatedly gave way to careful reports on the public’s discontent. Services on the train line where the accident took place resumed just 1½ days after the accident. Authorities wanted the tracks cleared, fixed up and ready to go within 24 hours but poor weather slowed those ambitions the China Daily reported. For some Chinese the speed in which authorities got the system rolling again was in the words of the New York Times “emblematic of a callous, unresponsive political culture that prioritizes instant results over public well-being and accountability.”

The Economist noted how poorly authorities handled the public relations of the crash. “They first tried to blame the weather (lightning) before faulting the institute that designed the signalling. Rescuers rushed to bury part of the wreckage, either in haste to get the service going again before all the survivors had been accounted for, or because they wished to hide technology (either Chinese, or some lifted from foreign companies). Corpses were not at first handed over to families. And Grandpa Wen took days to pay his respects to victims. He had been sick, he said, which raised more questions than it answered

Ian Johnson wrote in the New York Times, “In official, government-approved accounts of the accident, officials moved quickly to take charge of the situation. On Sunday morning, President Hu Jintao declared that rescue efforts were a top priority. The government also announced that three senior officials in the Railway Ministry had been fired. The railway minister was said to have taken charge of the rescue operation. But competing narratives already began emerging Sunday. On the feisty microblogging site Sina Weibo, postings said that the minister, Sheng Guangzu, who took over this year when his predecessor was fired for corruption, had been cornered by angry journalists after he dodged interview requests. [Source: Ian Johnson, New York Times July 24, 2011]

Other reports on the site said the ministry was burying parts of the wrecked trains near the site, prompting critics to say that the wreckage needed to be carefully examined for causes of the malfunction. More confusion emerged over efforts to portray nature as the culprit in the accident. Xinhua reported Saturday that the first train lost power when it was hit by lightning, and national television broadcasts emphasized pictures of lightning storms in the area. But later reports by Xinhua said the supposedly stalled train was under way when it was struck by the other train. Also left unexplained was why railway signals did not stop the second train before it hit the first one.

Burial of Railway Car and Quick Clean Up at the Wenzhou Train Crash Site

Railway authorities decided to bury the derailed first car of the oncoming train at the site of the accident. The railway ministry said the car was buried so a crane could move into position, according to a statement on its website. The ministry also said the trains contained valuable “national level” technology that could be stolen and thus must be buried “even though foreign companies have long complained that the technology was actually stolen from their trains.

After an online outcry charging a cover-up and destruction of evidence, the carriage was dug up and taken to Wenzhou for analysis. China Daily, the state-controlled English-language newspaper, noted that they had met the request of “many netizens.”

China's state news agency Xinhua has denied widespread rumours that railway authorities tried to conceal evidence by burying carriages. Citing an unnamed official with the Ministry of Railways, Xinhua said that "the problem of burying rail carriages and 'destroying evidence' does not exist during the handling of the whole of the accident".The report said that only the damaged parts of some carriages were buried at the site in order to facilitate clean-up and rescue operations.

Asked why the accident site was so hastily cleaned up, Mr. Wen said the government’s first priority was to rescue victims. As soon he learned of the accident Saturday night, he said, he called the railway minister with a two-word order: “save people.”

An official identified only as being in charge of a major train station told the Economic Observer, a Chinese economic weekly, said China's railway authorities usually destroyed evidence when an accident occurred. He said that burying the train car was a typical cover-up attempt. "The same thing is always done, but this time there was just more media attention," he was quoted as saying. The railway official was quoted as saying, "When there's a problem, railway officials think about how to avoid responsibility. [Source: Yomiuri Shimbun, August 2, 2011]

Chinese Research Firm Takes Responsibility for the Wenzhou Train Crash

A Chinese railway research institute took responsibility for the accident, which has been blamed on faulty signalling equipment. Railway authorities said a signal, that should have turned red after lightning hit the train that stalled, remained green, and rail staff then failed to see something was amiss, the state-run Xinhua news agency said. [Source: Fayen Wong, Reuters, July 28, 2011]

Reuters reported: “The Beijing National Railway Research & Design Institute of Signals and Communications Co. Ltd., in a rare admission of responsibility for a disaster, issued an apology, acknowledging it was the source of the deadly flaw. The Institute would "face up to shouldering responsibility, and accept any punishment that is due, and will strictly undertake pursuing culpability of those responsible", Xinhua reported, citing an institute statement. "Safety overrides all else, and high-speed rail safety is of even more overriding importance," said the Institute.

The admission of guilt came in the face of public ire about the accident that has escalated into angry accusations that officials had covered up facts and stifled media coverage to protect an ambitious rail expansion plan and the Communist Party's image of unruffled control. An editorial with the headline “No Development Without Safety” on People’s Net, the government-run Web site affiliated with the party’s leading newspaper, People’s Daily, said the Railway Ministry had warned of the risks of lightning in a notice four days before the crash. It said new procedures were needed to prevent accidents. But it noted that these measures had not been put into effect, implying that the railway had no emergency plans for trains struck by lightning. [Source: Ian Johnson New York Times July 24, 2011]

Wen Jibao Visits the Wenzhou Train Crash Site

20111105-Xinhua Wenzhou train crash 8_281n.jpg
Wenzhou train crash
Prime Minister Wen arrived in Wenzhou five days after the tragedy. He said he arrived so late because of illness. At an hour-long news conference at the site of the crash he promised a transparent investigation and pledged more focus on safety and greater accountability. “Our investigation must affirm our responsibility to the people, whether it was an equipment problem, a management problem, or a production problem,” Mr. Wen said. “We must get to the bottom of this. If there is any corruption exposed in the investigation, we will handle it according to the law, and the consequences will be severe.”

The prime minister credited the nation’s rail industry with tremendous progress, but said, “This incident reminds us that we should pay more attention to safety during high-speed rail construction.” On why he showed up so late the 68-year-old Wen said “I’ve been ill recently, on a sickbed for 11 days...”Today my doctor reluctantly allowed me to travel.”

Although news conferences of top leaders typically are broadcast live, China’s central television network, CCTV stuck to its normal programming throughout the event, prompting some Chinese to question whether the network was censoring the prime minister. Users of Sina Weibo, a microblogging site, kept up a running commentary. One writer questioned how Mr. Wen could have been confined to a sickbed for 11 days when the Chinese news media reported that he attended several meetings with foreign officials and hosted two sessions of the State Council, China’s cabinet. Others defended him.

Although Wen's visit appears to have gone some way toward salving public anger, many Wenzhou citizens are still furious that the accident happened at all, underscoring the challenge Beijing faces to win back people's confidence. “His job is not easy, with everyone below him being completely incompetent,” read one post, from a woman in Shanghai. Another, from a man in Urumqi, said: “Every time he appears, he looks more aged and tired. There are always disappointing officials who force him to worry more.”

Attempts by the Chinese Government to Bury the Wenzhou Train Crash Story

20111105-Xinhua Wenzhou train crash 358_291n.jpg
A week after the crash, Chinese media received an order from national authorities to "calm down" coverage. They were told to focus on positive news or information from the authorities, according to a copy seen by Bloomberg News. The Economic Observer, a Beijing-based national business weekly, was among publications that defied the gag order, printing an open letter to the rescued orphan Xiang on its August 1 front page starting "Dear Yiyi," which said: "This country has created one economic miracle after another. They claim that’s for people’s benefit, but wouldn’t slow down to listen to the living beings." [Source: Bloomberg News, September 18, 2011]

David Bandurski wrote in the New York Times, “From the outset, China’s government did its utmost to keep public doubts from gathering speed. The Central Propaganda Department instructed media across the country to avoid hard questions and focus instead on “stories that are extremely moving, like people donating blood and taxi drivers refusing to accept fares.” The overarching theme, it said, should be “great love in the face of great tragedy.” [Source: David Bandurski, New York Times, July 28, 2011]

Meanwhile, China’s rail ministry cited lightning as the cause of the accident, sidestepping questions of human error and institutional failure. When journalists asked pointedly how a young girl had been found alive after officials called an end to the rescue effort, the ministry again favored emotion over candor, calling the discovery a “miracle.”

Ordinary Chinese, primarily through the Internet, insistently pushed the Wenzhou tragedy front and center, refusing to accept the government’s rationalizations and distractions. Using Twitter-like platforms on an unprecedented scale, people have clamored for answers to a hornet’s nest of questions. How was the accident caused by lightning? Why was the train behind not aware there was a train in front? Why was the rescue effort halted so soon? Why was the wreckage piled up into shallow pits before there had been a proper investigation into the accident’s cause? Why has a list of victims not been made public?

Magazines and newspapers followed suit, reporting boldly on the facts and pressing for answers. At the very heart of all of these questions “and indeed of the tragedy itself “is a government that refuses to be held accountable for its decisions, and that admits no criticism when criticism might make the difference between bold vision and monstrous folly.

Train Accidents in China

20111105-Xinhua Wenzhou train crash 321n.jpg
Wenzhou train crash
China's train system is overtaxed. However accidents with fatalities are rare. Many more people die making train lines than riding on them. In 1997 125 people were killed and 90 were injured when a train heading north on the Guangzhou-Beijing line crashed into train stopped at a station in the Hunan province.

In December 2001, at least 28 people were killed when a train slammed into a bus at a railway crossing in the city of Artuz in Xinjiang. The bus “disintegrated completely.”

In August 2005, five people were killed and 30 were injured when a passenger train crashed into a cargo train in Liaonging Province. The accident was blamed on a signal failure that in turn was caused by electrical cables being stolen.

In March 2009, nine construction workers were killed when a construction site in Jiangsu Province for China’s high speed railroad between Beijing and Shanghai collapsed, burying the workers.

In August 2009, four people were killed and 50 were injured when a train derailed near Liuzhou city in Guangxi. The cause was a landslide that occured after days of heavy rain,

In June 2009, three people were killed and 60 were injured when two trains collided near Chenzhou in Hunan Province. Train cars derailed and careened into houses near the tracks.

In June 2010, a passenger train hit by landslides in a mountainous area near Fuzhou city in eastern Jiangsu Province derailed, leaving eight people dead and 55 injured. The train, bound for the tourist destination of Guilin, came off the tracks when it crashed into mounds of dirt and debris that fell on tracks from landslides caused by heavy rains. A team of rescuers, including police, firefighters and soldiers, converged on used the scene, pulling dozens of people trapped in the train. In some cases rescuers used heavy cutting and sawing equipment to to cut into the train, Eight of the 17 carriages of the train derailed and even flipped over. Heavy rains had deluged the area for several days. So much water had fallen that reservoirs were forced to release water, flooding low-lying and residential areas downstream. [Source: AP]

Big Train Accident in 2008

Wenzhou train crash
In April 2008, a high-speed passenger train jumped the tracks and collided with another train near the city of Zibo in the eastern province of Shandong, killing 72 people and injuring 420. The crash occurred just before dawn and involved a train heading from Beijing to the city of Qingdao. Nine of the train’s 10 carriages were knocked into a dirt ditch, with several cars falling on their side. It was the worst train accident in China in more than a decade.

The crash was blamed on speeding. Records show the train that jumped the tracks was traveling at a speed of 131kph over a section it was supposed to be traveling at 80kph. Local authorities were blamed for failing to order the Qingdai-bound train to slow down at a construction site, where an additional rail line was being built for the Olympics. Two high-ranking railway officials in Shandong were fired immediately. Six people, including the driver, were detained.

Most of the passengers were sleeping at the time of the accident. One who was standing in the aisle waiting to get off at an approaching station told AP, “I suddenly felt the train, like a roller coaster, topple, to one side and all the way to other side. When it finally went off the track many people fell on me.”

Another woman told AP, “I was a wake. I just got back from using the bathrooms. People who were sleeping, they got crushed to death and wouldn’t even know it..I crawled out of a window, Anywhere there was space to get out, people were trying to get out.” A 10-year-old boy in the hospital said, “I was sleeping so I don’t remember much. I don’t even know how I got here.”

Shanghai Subway Collision Leaves Hundreds Hurt

Two subway trains collided in a tunnel in downtown Shanghai, near Yu Yuan Gardens, injuring 284 passengers and requiring more than 500 passengers to be evacuated from the trains after the collision. Of the injured, 95 were admitted to hospitals or were under observation, the city health department said. No one was in critical condition, it said. State-run Xinhua news agency reported 20 people were in serious condition, and four foreigners were injured but none severely. Photos of the scene posted on Weibo, China's equivalent of Twitter, showed passengers covered with blood lying on the train or being helped by rescuers. Most injuries were not serious[Source: Steven Jiang, CNN, September 27, 2011]

It was the worst subway train accident in 42 years. CNN reported: Shanghai Shentong Metro Company, the city's subway operator, said a train on Metro Line 10 rear-ended another after an equipment failure at a station forced dispatchers to switch to manual mode."It's the darkest day since Shanghai Metro began its operations," Shentong said on its official Weibo account, apologizing to all riders and promising a thorough investigation.

One passenger on the first subway described to CNN the frightening moments after his train stalled on the track for about 20 minutes. "Suddenly we heard this loud noise -- the train started shaking and many people fell to the ground," said Duan Youxing, a recent college graduate. "Smoke came out between two conjoined cars and everyone just panicked."

Local media reported Metro Line 10's signal system was supplied by one of the companies that also manufactured signal equipment for the country's high-speed railway. That company's design flaws were blamed for a fatal bullet train collision in July in eastern China that killed at least 40 people. Metro Line 10 opened in 2010. It had another incident less than two months before the September crash. In July, a train on the line traveled in the wrong direction and the subway operator later said the accident was caused by a signal system malfunction during an equipment upgrade.

Some experts have long questioned the "great leap forward" strategy in constructing subway systems in cities across China, warning of potential safety issues. Shanghai, China's largest city, built the world's longest subway network in less than two decades. Shanghai Metro's first line opened in 1995, and now boasts 11 lines and more than 434 kilometers (270 miles) of tracks. It was not the first time there were problems on Line 10. Two months before a train took a wrong turn because of a signal failure, nearly leading to a collision. “The accident is an embarrassment for the Shanghai Metro operator because it had promised that the current signaling system would prevent trains from hitting one another,” the official China Daily newspaper said. The company that supplied signals for the Shanghai Metro also made the signaling equipment for the high-speed line in Wenzhou.

Services on Line 10 were shut across a 13-station stretch most of the day after the wreck. Full operations on the track resumed at 8:00pm., Shanghai Metro said. The company limited train speeds to 45 kilometers (28 miles) an hour. As Shentong restarted running Metro Line 10 some Chinese netizens responded angrily to the news. "The injured are still in the hospital and the cause is still being investigated, how dare you announce the resumption of service already -- and with so much pride?" wrote user Liang Shuxin on Weibo. "It only shows the authorities don't consider ordinary people's lives worthwhile."

Shanghai Subway Collision Caused by Power Failure Not Signals

Bloomberg reported that Shanghai’s subway operator said the crash that injured 284 people was caused by a power failure and manual error, a day after its chairman blamed the accident on signaling equipment. Controllers didn’t follow proper procedures after a power shortage disrupted signaling, Shanghai Shentong Metro Co. said in a statement. [Source: Bloomberg News, September 28, 2011]

Shanghai Shentong Metro’s Chairman Yu Guangyao told reporters hours after the accident that the collision happened because of a fault in equipment made by Alstom SA-backed Casco Signal Ltd. “The main cause of the accident has no relation with the signaling system,” Philippe Kasse, a spokesman for Levallois- Perret, France-based Alstom, said by e-mail yesterday. Casco Signal, a venture with China Railway Signal & Communication Corp., “can’t be held as responsible,” he said.

The accident, two months after a fatal high-speed train crash, has stoked concerns that China’s rapid construction of new transport links comes at the cost of safety. Shanghai’s subway and maglev-train network expanded more than sevenfold in eight years to 453 kilometers because of a growing population and demand during last year’s World Expo. “This is an alarm bell for the subway system after years of rapid growth,” said Jack Xu, an analyst at Sinopac Securities Asia Ltd. in Shanghai. “Investment in the sector may slow in the near term.”

Twelve Punished for Shanghai Subway Crash

In October 2011 AP reported: “A subway crash in Shanghai that injured nearly 300 people resulted from negligence, inadequate training and faulty installation of backup power systems, the city's safety agency said. It announced penalties for a dozen subway employees. Three train operators were removed from their posts, the Shanghai Administration of Work Safety said, while nine other subway system managers and workers were also punished for the crash of one subway train into another. [Source: Elaine Kurtenbach, AP, October 7, 2011]

The subway crash was a shock for Shanghai, a city of 23 million that had its entire transport infrastructure---roads, airports, ports, tunnels and subways---upgraded ahead of the city's 2010 World Expo. It occurred just two months after two bullet trains in east China's Zhejiang Province crashed, killing 40 people and injuring 177. The July 23 accident exposed festering resentments over the huge costs of the country's massive buildup of its rail system, especially its high-speed lines. The Shanghai accident highlights some of the risks of hasty construction and deployment of showcase infrastructure, especially given China's poor track record for industrial safety. The affected line---Line 10---operated by Shanghai Shentong Metro Group, is one of Shanghai's newest and most modern.

A loss of power on the line during repairs caused the signal system to fail and dispatchers then issued faulty orders that caused one train to rear end another as it sat still on the tracks in an area near the city's scenic Yuyuan Garden. The report said Shanghai Shentong's first mistake was in authorizing repair work at a station without having a contingency plan in case it disrupted the power supply. The repair work caused a loss of power to the station that led the signaling system to fail. "Shanghai Shentong should be people-oriented, put safety first, and draw deep lessons from the accident," the report said. It said the metro operator would face maximum financial penalties for its lapses, without giving any details.

The report also cited problems with installation of backup power from uninterrupted power supply---UPS---equipment, which should have kicked in to prevent any lengthy power outages. With the power out, subway operators then chose to direct trains on Line 10 via phone instead of electronic signals and ordered a train to stop in a tunnel between two stations. About half an hour later, another train started out from one of the stations and headed toward the halted train at a speed of up to 54 kilometers per hour (34 mph), until the driver saw the stationary train and immediately tried to brake. It crashed into the stationary train at a speed of 35 kph (22 mph). Although the train was crowded at the mid-afternoon time of the crash, the relatively slow speed helped to reduce injuries, most of which were light and not life-threatening, according to city officials.

High-tech automatic train protection systems are designed to improve safety while allowing more trains to travel within shorter intervals. Normally such systems prevent crashes by controlling train speeds and signaling the presence of any other trains on the line. The supplier of the signaling system for the line---a joint venture between a local company and France's Alstom SA---denied earlier claims by the subway operator that its equipment malfunctioned, saying the crash had nothing to do with its system.
