China's Fuxing bullet trains with "smarter" facilities will begin operation on June 25, running on railway lines across 18 provincial-level administrative regions in China, according to China Railway, the country's national rail operator.

A zippy step up from the existing CR400AF and CR400BF models, these ingenious trains move at a speed of 350 kilometers per hour. 

But there are many visible or invisible improvements.

The exterior design of the streamlined train adopted traditional artistic elements including dragon and phoenix as auspicious symbols.

Unlike other trains, the new one has an exclusive door for the drivers, enhancing safety and convenience.

It uses the Ethernet-based 5G technology to control the whole operating system on the train and provide Wi-Fi access to passengers.

Increased monitoring points on board will better the precision of the train operation and predict possible malfunctioning in real-time.

A new type of inverter air conditioner will save at least ten percent of energy consumption on the train.

Each new train will have an accessible carriage and a vending machine, also offering braille instructions for the visually impaired.

Smart smoke detectors and intelligent light and sound adjusting systems have also been installed. 

More mobile phone charging points, including wireless ones, are also available.

This is the upgraded version of smart Fuxing bullet trains that first operated on the Beijing-Zhangjiakou high-speed railway line in December 2019.

That line was designed to offer intelligent high-speed railway service for 2022 Beijing Winter Olympics and experiences for later upgrading.

Now, there are two types of formations to go into service. One has standard eight carriages with 578 seats and the other is extra-long with 17 carriages and 1,285 seats.

They will begin traveling on major lines across China on June 25, and more will come later, according to China Railway.
