Even in China the trains are only half full:

The Chinese Academy of Sciences (CAS) reported to the State Council recently, urging the large-scale high-speed railway construction projects in China to be re-evaluated.

Some local media have reported recently that the recently enabled Wuhan – Guangzhou high-speed rail is currently running an average daily attendance of less than half capacity, while the newly opened Shanghai-Hangzhou high-speed rail attendance is even lower.
