China’s high-speed rail nears 50,000km milestone – but debt and profit concerns mount
The network dwarfs global rivals and has reshaped domestic travel – but analysts warn debt levels cannot be ignored

But some analysts have urged officials to hit the brakes.
“Many newly built HSR lines should not have been built, if assessed according to the standards set by the central government,” said Zhao Jian, a professor at Beijing Jiaotong University.
As a manufacturing powerhouse, China needs greater freight capacity – especially for bulk commodities – but high-speed rail, which typically runs at about 300km/h, is limited to carrying passengers as the speed of travel is unsuitable for transporting heavy loads, he said.
In March 2021, the State Council issued guidelines calling for stricter assessments of new lines where parallel routes already exist. But the network continues to expand, reaching 48,000 kilometres by the end of 2024.
China State Railway Group, the main operator, has set a 50,000-kilometre target for this year despite accruing a mountain of debt since it launched construction on the network in 2008 – with levels reaching 6.2 trillion yuan (US$863 billion) by the end of 2024, according to the firm’s balance sheets.
The debt-to-asset ratio stands at 63.5 per cent, with most funding financed through bank loans and bond sales, it said.
