China Rail Chief’s Firing Hints at Trouble
The statement underscored concerns in some quarters that Mr. Liu cut corners in his all-out push to extend the rail system and to keep the project on schedule and within its budget. No accidents have been reported on the high-speed rail network, but reports suggest that construction quality may at times have been shoddy.
A person with ties to the ministry said that the concrete bases for the system’s tracks were so cheaply made, with inadequate use of chemical hardening agents, that trains would be unable to maintain their current speeds of about 217 miles per hour for more than a few years. In as little as five years, lower speeds, possibly below about 186 miles per hour, could be required as the rails become less straight, the expert said.
Strong concrete pillars require a large dose of high-quality fly ash, the byproduct of burning coal. But the speed of construction has far exceeded the available supply, according to a 2008 study by a Chinese railway design institute.

Those power failures by lightening strike and "human errors" don't happen in other country's HSR system. Somebody cut corners.Wenzhou crash was a power failure caused by human error
Germany, yes. That was more than 10 years ago.in recent years Germany
That was a regular commuter train, not Shinkansen.and Japan's high speed trains both had more serious derailment and casuality than the Wenzhou accident,
