The train is automatic driven. With intelligent monitoring and warning system, it can realize on-route fault early warning and initiate repair work when needed, compared with planned repair work on traditional subway trains.

The train can run at a speed of up to 140 kilometers per hour, faster than traditional subway train. What's more, it runs more stably because it uses full active suspension technology for the first time.

Thanks to the new sound-proof materials, the noise within carriages is five decibel lower than traditional carriages.

The train is also adaptable to bad operational environment. It can run smoothly in high or low temperatures, on high altitude, small-radius curves and big ramps.

The train is expected to undergo track test in July.
