According to the Beijing Daily, the new energy intercity electric vehicle group developed by China Railway Changke Co., Ltd. arrived in the grasslands of Inner Mongolia to carry out tests.

It is reported that this is my country's first new energy intercity EMU that realizes the conversion of two power modes of power grid energy supply and battery energy supply. Thanks to the new energy supply technology, trains can not only walk freely on intercity or urban tracks, but also run normally in extreme geographical environments such as sandstorm and high cold. Without contacting the grid, the train set can still achieve a range of more than 200 kilometers.

In addition, in the aspect of controlling the noise inside the car, the tram group achieves the effect of reducing the noise inside the car through the adoption of new sound insulation materials, the optimization of the sound insulation structure and the partition of the sound source transmission path. At the same time, the train set also achieved full coverage of WiFi signals.
