China has introduced a new “bullet” high-speed train, which is designed for extremely cold climates.
The “CR400AF-G”, which can operate in temperatures as low as minus 40 degrees Celsius, is part of the “Fuxing” series of high-speed, multi-unit electric trains developed and operated by the government-affiliated China Railway Group.
The train, which was launched in Beijing on January 6, will operate on a new high-speed line linking the Chinese capital with destinations in the northeast, including the cities of Shenyang and Harbin, the latter of which is famous for its annual festival. of snow and ice. Authorities have not yet announced when the train will start operating.
In a post on the Chinese social media site “WeChat,” China Beijing Railway Group, part of the China Railway Group Corporation, operated various components of the train that help it withstand the cold temperatures.
The train components include chrome-moly alloy nails, a material that can withstand extremely low temperatures, as well as silicone sealing strips, which prevent snow and ice from entering the train body. Not only that, but also the brake control devices, which are heat resistant, with stainless steel tubes, which consist of heating devices.
China is not alone in having to adapt its express trains to harsh conditions.
In 2020, Japan launched its latest record-breaking express trains as it not only runs faster, but can also take passengers to safety in the event of an earthquake.
The train can travel at speeds of up to 360 kilometers per hour, but the operating speed will be limited to 285 kilometers per hour, and it has an automatic control system that allows faster braking in an emergency.
The train is equipped with a self-propelled lithium-ion battery, the first of its kind in the world. Therefore, this system allows the train to travel a short distance on its own during a power outage. It will also make it possible to transport to a safer place at low speed, if passengers are stranded in a high-risk area, be it on a bridge or in a tunnel, for example during an earthquake.
The N700S entered service on July 1, serving the Tokaido Shinkansen Line, which connects Tokyo Station with Shin-Osaka Station, in the city of Osaka.
The world’s largest high-speed rail network
Today, China is home to the world’s largest high-speed rail network, stretching for more than 37,000 km, and the fastest commercially operated train known as “Shanghai maglev”.
With a maximum speed of 431 kilometers per hour, the train connects Shanghai Pudeng International Airport and Longyang Road on the east side of Shanghai.
Around this time last year, China unveiled a 174-kilometer high-speed railway linking Beijing with the 2022 Winter Olympics host city Zhangjiakou, reducing travel time between the two regions from three hours. 47 minutes.
The train running on this line is reported to be also part of the Chinese “Fuxing” chain and can reach speeds of 350 kilometers per hour without a driver, and is said to be the first of its kind in the world.
According to China Railway Group, 1,036 “Fuxing” series high-speed trains have been operated since they were first launched in 2017.
