China's bullet-train ambitions hit a number of snags in 2011 and ultimately slowed down. It was not what the Ministry of Railways had pictured.

Last December, when China became the first Asian nation to host a global high-speed rail summit, Liu Zhijun, the country's railways minister at the time, said China had 7,531 kilometers of railways running at 200 km/h and faster, including 4,322 km of newly laid track.

More than 10,000 km of high-speed railways were also being rolled out across the country, he said, with the majority set to open to public in 2013. By 2020, China's high-speed network would increase by 16,000 km, he said.

"People were excited and optimistic about the prospect," said Li Kun, a researcher specialized in railways at the comprehensive transport institute of the National Development and Reform Commission (NDRC), the country's top economy planner.

"Soon after, though, they were gripped by a feeling of insecurity and sadness, and society began to question the development of high-speed travel," he said.

First, Liu was investigated and subsequently removed from his post for graft in February, and then probes were launched into other senior railway officials.

When it emerged that some unqualified contractors and suppliers could have won contracts through their special relationships with corrupt officials, people began to wonder how much of the new railway might have quality problems.

To address the issue, Sheng Guangzu, who replaced Liu as railways minister, said in April that high-speed trains would be operated at slower speeds, adding that more services would also be laid on.

On June 30, the landmark Beijing-Shanghai bullet train was launched, offering services at both 300 km/h and 200 km/h, both slower than its designed speed of 380 km/h.

In its first month, the 1,318-km line reported some glitches, which fueled suspicion over its safety.

Again, the Ministry of Railways moved to allay fears by calling the faults teething problems, and insisted its high-speed system had been built to the highest standards.

Not long after that, a bullet train rear-ended another one on July 23 near Wenzhou, East China's Zhejiang province, killing 40 people and injuring almost 200 more.

The tragic accident rocked the nation, prompting calls for authorities to carry out checks on high-speed rail services.

Under pressure, the Railways Ministry ordered another slowdown, this time including the two short lines - Beijing to Tianjin and Shanghai to Hangzhou - that had been kept at 350 km/h as symbols of China's technological advancement.

Then came the third scandal in October, when railway tunnel expert Wang Mengshu disclosed to the media that high-speed rail projects spanning some 10,000 km had been halted because of funding shortages.

He said the money from the central government's stimulus plan, worth 4 trillion yuan ($586 billion at the time), had dried up, and that the ministry could not borrow any money from the banks due to its tarnished image after the Wenzhou crash and the country's tightened monetary policy.

Insiders said the funding problem emerged at the beginning of this year.

"Too many rail projects have been started in a rush since 2008," said the manager of a Beijing company that helps the railway authority get land permits for construction, who spoke on condition of anonymity.

"The government needed as many railway projects to start as possible so that it could trigger demand following the global financial crisis," he said.

The rush saw many projects start without careful planning, he said, and some routes that did not have on-site tests pass through land that could subside in the future.

The manager added that his company had received no business from the high-speed railway sector since the start of 2011.

Wang said that without the money from the ministry, contractors were left owing large sums to suppliers and had failed to pay workers' salaries for up to six months.

In November, the central government allocated 200 billion yuan to help the Ministry of Railways pay off its creditors.

Wang and other experts said the money would be enough for the ministry to settle most of its debt, worth an estimated 250 billion yuan.

To resume construction and complete the projects, however, observers said it would take at least another 200 billion yuan.

"No one knows exactly what the central government will do about the railway sector," said Zhao Jian, a professor of transport at Beijing Jiaotong University. "It's something the government has to think carefully about."

A turning point

In the eyes of railway experts, the dramatic events of this year have not necessarily been a bad thing.

John Scales, lead transport specialist at the World Bank's Beijing office, said the obstacles are like "a wakeup call" to the Ministry of Railways, to help it get back to the basics - quality, safe operation and stable finance.

It is an opportunity for the ministry to slow down, he said.

Following the stimulus package in 2008, China has implemented its mid- and long-term railway plans at a frenetic pace.

"If China keeps the pace of construction of the past few years, the long-term plan will be completed five years (ahead of schedule)," Scales said.

However, experts agree that slowing down the sector does not mean halting investment.

Paul Amos, a consultant to the World Bank, said China's rail network is the "least dense but heaviest used" system in the world, meaning it needs continuous investment and development.

China's passenger rail saw year-on-year growth of 11 percent from October last year to October 2011.

"(The growth) is pretty healthy, considering what happened this year. It would be a mistake to stop investing in the system," Amos said.

He suggested that work be concentrated on the main corridors of the planned high-speed network, as other projects can wait.

The reason, he explained, is that major lines are usually built to meet surging transport demands, and once in use they will generate good revenue streams to prevent the debt crisis from worsening.

Li Kun at the NDRC had a similar opinion.

"When Japan developed its high-speed railway in the 1960s, its economy was not as good as ours is now," he said. "The doubts over developing high-speed railways are a good thing, but it's still necessary for China to maintain fast development of some bullet train lines."

He brushed off worries about huge debts, however.

"Every construction project incurs debts," Li said. "The level of debt is decided by the traffic and revenue stream on a railway. When the revenue doesn't match the input, there will be a debt crisis.

"What should be done is to develop in accordance with actual demand. Development should not be blind," he added.

In the eastern areas of China, where the population is dense and economy dynamic, businesses rely heavily on road and air transport to meet logistics demands. So, Li said, development of high-speed rail in the east should "continue to be fast-tracked".

As for western areas, development could be taken step by step, he said, adding that trains should not run that fast.

However, money is still a problem. Railway projects are funded in three parts - the central government pays 40 to 50 percent, the Ministry of Railways borrows money from the banks to cover 40 percent, and provincial authorities cover 10 to 20 percent.

Once completed, the ministry uses its income, mainly from cargo transport, to cover the operation costs of both cargo and passenger rail, and slowly pay back its loans with interest.

Railway officials said that the ministry has even made a slight profit in previous years.

Yet, as construction of high-speed railways has led to huge debts, industry observers warn that the ministry may no longer be able to pay the bills, and that the old pattern is unsustainable.

Media reports quoted analysts saying that the Railways Ministry owes almost 2 trillion yuan due to high-speed rail construction. Each year, the ministry has to pay 20 billion yuan in bond interest alone, a result of the 458.7 billion yuan in bonds it issued during 1995 and November this year.

Tunnel expert Wang Mengshu said that it is time the government takes over the debt, which according to World Bank consultant Amos is common in other countries.

Observers say the central government has made some gestures, as corporate bonds issued by the ministry recently became "government-supported" bonds.

However, some experts went further and added their voices to calls for a reform of the railway sector, which has been ongoing for 20 years.

The Ministry of Railways is often referred to as "a massive monopoly", not only because it has more than 2 million full-time employees and is responsible for 91,000 km of railways (more than twice the circumference of the Earth at its equator), but it is also the only State agency that has its own independent legal system.

Zhao at Beijing Jiaotong University said previous calls for reform had failed because the ministry insisted it has this ability to gather the resources for laying high-speed tracks and increase transport capacity.

"Yet, the development pattern has been proved flawed, including not being market-oriented enough. Its debt of 2 trillion yuan has begun to affect the economy," he said. "That is the price of resisting reform."

Li at the NDRC suggested the ministry could reform its management system and list some of its assets on the stock market, so as to reduce risk.

However, Zhao said he believes the reforms should be more thorough, as it is "commonly held that the ministry should be stripped of its enterprise management role".

"The problem now is: Who will shoulder the huge debt," he said. "If a newly established railway company picks up the debt, it will go broke straightaway. It looks like there is no other choice but to let the government shoulder the debt, which might affect the economy.

"This makes reforming the railway sector a hard decision for the central government to make," he added.
