(CNN) — China has unveiled a brand new high-speed bullet prepare designed for very chilly climates.

The CR400AF-G prepare, which may function at speeds of as much as 350 kilometers per hour (217 mph) in temperatures as little as -40 levels Celsius (-40 levels Fahrenheit), is a part of the Fuxing sequence of high-speed electrical multiple-unit (EMU) trains developed and operated by the state-owned China State Railway Group.

The prepare, rolled out in Beijing on January 6, will run on a brand new high-speed line connecting the Chinese language capital with northeastern locations together with cities Shenyang and Harbin — the latter of which is famed for its annual snow and ice competition.

Officers have but to announce when the prepare will start operations.

In a submit on Chinese language social media web site WeChat, the China Railway Beijing Group — a part of the China State Railway Group Firm — ran by a number of of the prepare’s optimized elements that help its potential to face up to chilly temperatures.

The brake system of China's newest bullet train was designed to withstand extremely cold temperatures.

These embrace: bolts made with chromium-molybdenum alloy — a cloth that endures extraordinarily low temperatures; silicone sealing strips, which stop snow and ice from stepping into the prepare physique; temperature-resistant brake management units; and stainless-steel pipes geared up with heating units.

The prepare additionally includes a streamlined low-resistance design, to assist lower vitality consumption, and a light-weight aluminum alloy physique.

In a report by state-owned newspaper China Day by day, Zhou Tune, director of the China Railway Beijing Group’s bullet prepare middle, provided an analogy to clarify the brand new prepare’s brake system: “If the prepare stops in Harbin (one in all China’s coldest cities in northernmost Heilongjiang) for an hour, due to the extraordinarily chilly climate, the braking system can simply freeze if it stops shifting for some time. The brand new system will allow the brakes to maneuver once in a while even when the prepare stops, like an individual who stamps his toes to maintain heat in chilly climate.”

China is not alone in having to adapt its bullet trains to excessive situations.

In 2020, Japan launched its newest record-breaking bullet prepare and does not solely run sooner and smoother — it is also in a position to transport passengers to security within the occasion of an earthquake.

The N700S can run as much as 360 kilometers per hour, nonetheless the working velocity is capped at 285 kilometers per hour.

The prepare has an upgraded automated management and braking system that permits it to halt sooner in case of an emergency and is fitted with a lithium-ion battery self-propulsion system — the primary of its form on this planet.

This method permits the prepare to run for a brief distance by itself throughout an influence outage and can make it potential for it to maneuver to a safer location at low velocity if stranded in a high-risk space — on a bridge or in a tunnel, for instance — throughout an earthquake.

It entered into service July 1 and serves the Tokaido Shinkansen line, which hyperlinks Tokyo Station and Shin-Osaka Station in Osaka.

World’s largest high-speed rail community

As we speak, China is residence to the world’s largest high-speed rail community, which stretches over 37,000 kilometers, and the quickest commercially working prepare — the Shanghai maglev.

Working on the prime velocity of 431 kph, the prepare hyperlinks Shanghai Pudong Airport and Longyang Street within the jap facet of Shanghai.

This time final yr, China unveiled a brand new 174-kilometer high-speed railway line connecting Beijing with 2022 Winter Olympics host metropolis Zhangjiakou, slicing the journey time between the 2 from three hours to 47 minutes.

The prepare working on that line can also be a part of China’s Fuxing sequence and might run as much as 350 kilometers per hour (217 mph) and not using a driver — mentioned to be a world first.

In keeping with the China State Railway Group, 1,036 Fuxing bullet trains have been put into operation since 2017, when the sequence first launched.
