The Wenzhou bullet train disaster has called into question the pace of expansion of the high-speed-rail network and put the breakneck race for development on trial in the court of public opinion.
The crash, which killed at least 39 people, has caused nationwide soul-searching about the hasty expansion over the past decade.
'The leap-forward growth of the rail sector apparently goes against natural laws to some extent,' says Xu Yifa, a former train driver who became director of Zhengzhou's railway bureau. 'We must value quality and safety over speed.'
The cause of the crash - when a Beijing to Fuzhou bullet train rammed into a slow-moving or stationary Hangzhou to Fuzhou train - hasn't been determined.
But many analysts are blaming the railway ministry and its disgraced former minister, Liu Zhijun.
The public and media have launched unprecedented attacks on the railway system, one of the most monopolised sectors in the mainland's economy.
In addition to those killed, nearly 200 people were injured in the collision last Saturday, in which four carriages were forced off a viaduct and two more were derailed.
