BEIJING (AP) — China has frozen approval of new railway projects and halted some bullet train manufacturing, stepping up an overhaul of its controversial high-speed network after a July collision that killed 40 people.
The crash, along with delays on a new Beijing-Shanghai line blamed on equipment failures, embarrassed the communist government and fueled public anger at a bullet train network that critics say is dangerous and too costly.
The railway minister announced the moratorium on new rail projects Wednesday and promised a nationwide safety inspection. He also announced further speed reductions in the top speed of bullet trains following cuts in April.
"This accident exposed the weaknesses lying in the railway transportation safety and management," said Sheng Guangzu in comments posted on the Cabinet website.
The announcement adds to signs Beijing is scaling back plans that called for expanding the high-speed network to 8,000 miles (13,000 kilometers) of track by the end of this year and 10,000 miles (16,000 kilometers) by 2020.
The system is a prestige project for the Communist Party and is meant to showcase China's growing technological prowess. But the July 23 crash made it a target for complaints about the human cost of recklessly fast development.
Meanwhile, a state-owned manufacturer said it will suspend production of its CRH380BL trains used on the Beijing-Shanghai line while it investigates equipment failures.
China North Locomotive and Rolling Stock Ltd. gave no details in a statement issued through the Shanghai Stock Exchange. But the official Xinhua News Agency said trains "abnormally stopped" three times due to faulty sensor signals. The newspaper Shanghai Daily cited sources who said there were more than 40 breakdowns since late July but did not say how many involved equipment from the same producer.
There was no indication the production halt was linked to the crash near the southern city of Wenzhou. Authorities blamed that disaster on a lightning strike that caused one train to stall and a sensor failure that allowed a second train to keep moving on the same track and slam into it.
A CNR subsidiary, CNR Changchun Railway Vehicles Co., produced 24 of the planned 96 trains to be used on the Beijing-Shanghai line, Xinhua said. The company statement said plans call for the company to produce 17 more CRH380BL trains this year.
Experts have been sent to examine train sensors provided by a foreign supplier, Xinhua said, citing its deputy general manager, Zhao Minghua.
"The breakdowns make us realize that we must conduct strict checks for suppliers' products," Zhao was quoted as saying.
China has the world's biggest train network, with 56,000 miles (91,000 kilometers) of passenger rail. Trains are overloaded with passengers and cargo, and critics say the money would be better spent expanding cheaper, slower routes.
Critics have expected changes since the bullet train lost its biggest official booster when the former railway minister was dismissed in February amid a corruption investigation.
In the speed cuts announced Wednesday, Sheng said second-tier trains scheduled to run at 155 mph (250 kph) will slow to 125 mph (200 kph).
In April, the top speed of the fastest lines was reduced from 220 mph (350 kph) to 190 mph (300 kph) after Chinese railway researchers warned the planned speeds were dangerously fast and would waste energy.
Ticket sales for high-speed lines linking Shanghai with Beijing and the cities of Nanjing and Hangzhou will be suspended while schedules are reorganized, the Shanghai Railway Bureau said Thursday.
It said the suspension affects tickets for departures starting Tuesday and gave no indication when it would end. An employee who answered the phone at the bureau declined to give more details or his name.
