In January 2021, China unveiled the CR400AF-G, a high-speed bullet train designed to operate in
temperatures as low as -40°F (-40°C). The train, part of the Fuxing series developed by the China State
Railway Group, can reach speeds of 217 mph (350 km/h) and connects Beijing with northeastern cities like
Shenyang and Harbin, the latter famous for its annual snow and ice festival.
The CR400AF-G boasts several cutting-edge features that enable it to withstand extreme cold:
🚄 Chromium-molybdenum alloy bolts that endure ultra-low temperatures
🚄 Silicone sealing strips to prevent snow and ice from entering the train body
🚄 Temperature-resistant brake control devices
🚄 Stainless-steel pipes with built-in heating devices
The train’s streamlined, low-resistance design and lightweight aluminum alloy body also contribute to
reduced energy consumption.
One standout feature is the brake system, which prevents freezing even when the train stops for extended
periods. The new system enables the brakes to move from time to time even if the train stops, like a person
who stamps their feet to keep warm in cold weather.
With the launch of the CR400AF-G, China further solidified its position as a global leader in high-speed rail
technology. The country boasts the world’s largest high-speed rail network, spanning over 22,991 miles
(37,000 km), and the fastest commercially operating train – the Shanghai maglev, which reaches speeds of
268 mph (431 km/h).
Just as China’s new bullet train pushes the boundaries of what’s possible in extreme cold, at Tsamouris, we
strive to provide fastening solutions that excel in even the most demanding environments.
