High-speed sleeper trains begin operations in Shenzhen

A high-speed train dubbed the "mobile hotel" departed from Shenzhen on Saturday. The double decker train's design is similar to business class on flights.

The berths are parallel to the corridor and face the direction the train is traveling.

In addition, in order to facilitate passengers' use of electronic equipment, each single space is equipped with a USB socket. The ceiling lamps above the berths can be controlled independently.
