Superconductingelectric maglev (SEM) technology is one of the key strategic options forground-based high-speed and ultra-high-speed transportation. It offersadvantages such as efficiency, convenience, safety, reliability, energyefficiency, environmental friendliness, intelligence, and comfort. Thistechnology is adaptable to various scenarios, including ground lines, tunnellines, and low-vacuum pipelines. As such, SEM technology is regarded as one ofthe ′commanding high grounds′ of global rail transit technology. SEMtransportation system is an essential choice for building rapid transportchannels between megacities and advanced economic zones in China. It alsoprovides critical support for optimizing national spatial planning, promotingregional coordinated development, and accelerating the construction of anintegrated and multi-dimensional transportation network.

To implement theimportant directives given by General Secretary Xi Jinping during his visit toCRRC Changchun Railway Vehicles Co., Ltd. (hereinafter as ′CRRC Changchun′),and to accelerate independent innovation while maintaining China′s leadershipin the rail transit sector, CRRC Changchun, as a leading enterprise in thetransportation equipment manufacturing field in China, has made fruitfuladvancements in the maglev domain after comprehensive preparation. With overthree decades of accumulated expertise, CRRC Changchun achieved remarkablescientific research and development results, culminating in the release ofChina′s first SEM prototype vehicle in July 2024.

Theindependently developed SEM prototype vehicle by CRRC Changchun features acarbon-fiber composite body, multi-mode articulated suspension framework,full-scale high-temperature superconducting magnets, an onboard cryogenicrefrigeration system, and an induction power supply system. This innovation significantlyadvances independent innovation and engineering in maglev transportationtechnology. Moreover, it fosters horizontal integration across the industrychain, including superconducting materials, linear traction, cryogenicrefrigeration, and vacuum maintenance, injecting new momentum into sustainingleadership in high-speed rail transportation technology.

CRRC Changchun′sSEM prototype vehicle has the following features and merits:

Efficiency andConvenience. The SEM vehicle features a large suspension guidance gap, reducedvehicle-track coupling force, and lower sensitivity to track irregularities,providing significant speed enhancement potential, with a maximum operatingspeed of 600 km/h, which bridges the speed gap between high-speed railway andairplanes. This higher speed level solution supports the construction ofChina′s multi-dimensional transportation network and enhances the collaborativedevelopment efficiency of urban clusters.

Safety andReliability. The vehicle operates entirely within a U-shaped semi-enclosedtrack beam, eliminating derailment risks. Its onboard magnets, throughelectromagnetic induction with trackside suspension coils, counteract gravityto achieve passive self-stabilizing suspension within the U-shaped track, whichgreatly enhances system reliability.

EnergyEfficiency and Environmental Friendliness. In the superconducting state, thevehicle′s suspension and propulsion system has no resistance losses, withelectric currents circulating within the superconducting coils in a closed loopwithout external excitation power, enabling operation for hours during poweroutages and ensuring low energy consumption at high speeds. The use ofhigh-temperature superconducting materials eliminates reliance on scarcedomestic liquid helium resource. The streamlined vehicle exterior profiledesign minimizes aerodynamic drag, and the structure incorporates new materialslike carbon fiber, achieving lightweight construction while meeting highaerodynamic load demands.

The SEM system utilizes top-tier automated driving technology withmultiple operational modes, including standard, degraded, and emergency modes.Meanwhile, the vehicle incorporates 5G vehicle-wayside communicationtechnology, bearing subsystems including multimedia dispatch and coordination,operational state monitoring, with fast data transmission speed and stronginterference-resistant capability. The vehicle also features ergonomicallyadjustable seats with seamless controls, ensuring comfort and enhancing thepassenger experience.

Looking ahead,it is essential to lead the development of strategic emerging industries andaccelerate the creation of new productive forces. The Third Plenary Session ofthe 20th CPC Central Committee places high-quality development in more pivotalposition, focusing on deeply integrating technological and industrialinnovation, fostering emerging industries, and planning for future industries.CRRC Changchun will fully leverage its position as a leading enterprise ininnovation, uphold principles regarding ′matters of national significance′,devote to the ′Four Orientations′ strategic guidelines, and implement nationaltechnological innovation policies with high standards and quality.
