High-speed train travel in China won’t be limited by exclusive daytime operations anymore.

China is set to introduce “red-eye bullet trains” that can run overnight on a regular basis in 2016 as a way to increase railway operating efficiency, says a source with the China Railway Corporation (CNR).

Caixin reports the CNR as saying that even though high-speed red-eye trains weren’t previously available “due to lack of operating experience”, they are now “well capable of guaranteeing the safety of the nighttime operations” after having “accumulated rich experience after operating high speed trains for nearly a decade”.

The speed of the overnight train will not exceed 250 km/h at first, but is expected to be raised to 350 km/h soon afterwards, the source said.

Although the Caixin report mentioned that the high-speed red-eye was only previously available on a small scale basis during the Spring Festival travel rush, the service has appeared before elsewhere.

Beside a Beijing-Shanghai route that had been available on a limited basis, we had previously told you about a high-speed red-eye train route between Shanghai, Shenzhen and Guangzhou operating at the beginning of 2015. Costing RMB 800, the train departed at 8pm and arrived at its destination at 7 the next morning.
