One of the two train models, shown at the Rail+Metro China 2018, is a double decker with eight compartments, developed to meet demand for large passenger numbers for inter-city railways, the company said.

The train with 820 seats has a maximum capacity of 1,708 passengers, which is 40 percent more than the capacity of existing trains. The train units are equipped with advanced audio-visual entertainment facilities. With comfortable interior space, the train has independent toilets for disabled persons.

Yang Ying, deputy chief engineer with the company, said that the double-decker can run at a speed of 160 km/h, which can be made faster through system upgrading.

The other model has a permanent magnet synchronous motor, the first time for China-developed high-speed trains to use such technology. The electric motor is lighter and more power-efficient than existing ones.
