Maglev trains float above their tracks through cutting-edge magnetic levitation technology. We have the efforts of CRRC, a state-owned Chinese train manufacturer, to thank for these innovative trains coming back strong. Ever since the company established the new model in 2021, management has focused on improving productivity. Perhaps most importantly, they are committed to providing an exceptional passenger experience on their high-speed trains.
The attraction of maglev trains is largely due to their quiet operation. Once aboard, passengers are often treated to a peaceful ride. They are struck by the soft, almost eerie, hum created by the electromagnets, a jarring contrast to the clattering cacophony of conventional rail. This absence of mechanical racket also plays a role in creating a more comfortable ride overall, one that’s making maglev a more alluring choice for travelers.
Magnetic levitation technology makes it possible for these trains to hover above their dedicated track systems. In fact, they can already hover just 10mm above the ground! This limited production, one-of-a-kind feature employs an electromagnetic or electrodynamic suspension system. Specifically, it means no friction like found in a traditional rail system, allowing for quick acceleration and high speeds.
Now, scientists have turned their attention to a big disadvantage of maglev trains. Specifically, they wanted to pinpoint the phenomenon dubbed “tunnel boom.” When these trains dive into tunnels at high speed, it creates intense concussive shockwaves. These waves can lead to disruptive sonic booms, shattering what is otherwise a peaceful high-speed travel experience. Earlier this year, researchers developed unique sonic barriers for subway tunnel mouths. MonotoneAI Then our buffers can dampen those shock waves by 96% or more!
The new solution to the soundproofing problem features 100-meter-long buffers and a porous coating of the tunnel structures to absorb sound. These buffers allow for accumulated air to escape prior to the train entering the tunnel mouth, greatly reducing the occurrence of tunnel boom. It’s the same mechanism that makes a silencer on a firearm effective. …[it] is incredibly effective at reducing the “pounding” impact noise felt by residents around our tunnels.
China’s maglev trains first went into operation in 2004. With both trains they linked Pudong Airport to Shanghai’s city limits, and both trains set a world record of 460 km/h (286 mph). This record still stands undisputed for rail vehicles operating in public, commercial service on a daily basis. The newest version of maglev technology has really taken off. It can now reach speeds of 600 km/h (approx. 370 mph).
Looking ahead, China will eventually build longdistance maglev links and, to feature points, a maglev BeijingShanghai highspeed rail connection. This long-awaited and ambitious project will cut travel times from 4.5 to only 2.5 hours. It’s going to make rail a compelling choice versus short-haul air travel. Flights produce on average over seven times the CO2 per mile traveled compared to high-speed rail systems. This point underscores some of the amazing environmental benefits of taking the train instead of flying.
High-speed rail tickets in China are still cheaper than flying. A standard fare is about ¥ 600, whereas air fares can go as high as ¥1,200 on comparable itineraries. This unique pricing strategy has facilitated the expedited adoption of high-speed rail throughout the country.
China has the world’s largest high-speed rail network, which currently spans more than 48,000 km (30,000 miles). This impressive network of trains and buses helps make intercity travel seamless within the United States. It cements China’s growing role as a global leader in high-speed rail technology. Just as Japan is winning the global competition for high-speed rail systems. By connecting Tokyo and Osaka via Nagoya, the Chuo Shinkansen will greatly improve connectivity across Asia’s 2nd largest country.
