Maglev Technology Redefines The Limits Of Rail Speed As Countries Compete For Leadership In Innovation
Japan reached the historic milestone of 603 km/h with magnetic levitation trains in 2015, consolidating its position as a global reference in high-speed transportation. This achievement was accomplished by the L0 Series Maglev from Central Japan Railway Company in Yamanashi. This performance surpassed the previous record held by the French with the TGV, which had reached 574.8 km/h in 2007.
These numbers represent more than just speed: they reveal decades of research, billions in investments, and the strategic quest for technological leadership. Today, France, China, and Japan compete for the top spot, but even Brazil is starting to envision a place in this race.
Conventional Trains And Magnetic Levitation Trains
High-speed conventional trains, such as the French TGV or the Japanese Shinkansen, rely on steel wheels and reinforced tracks. They offer proven efficiency but are constrained by the physical limits imposed by friction. The result is constant maintenance, wear and tear on parts, and high costs.

On the other hand, magnetic levitation trains (maglev) eliminate this friction. By floating above guide tracks through magnetic fields, they can achieve much higher speeds. Japan uses the EDS system (electrodynamic suspension with superconductors), while China operates the EMS (electromagnetic suspension) in the Shanghai maglev, which reaches up to 431 km/h in commercial operation.
Who Is Behind These Innovations
The evolution of this sector has clear protagonists. In France, SNCF and Alstom were responsible for the TGV. In Japan, companies like Central Japan Railway Company and Kawasaki Heavy Industries shaped the Shinkansen and the maglev. In China, the state-owned CRRC dominates the production of trains that operate on both conventional tracks and maglev lines.
In the scientific field, figures like Hermann Kemper, considered the “father of maglev,” and Japanese engineers like Eiji Nakatsu, who redesigned the bullet train inspired by the beak of the kingfisher, have helped shape the history of high-speed transportation.
The Dispute Between Japan, France, And China
Each country seeks to showcase its advantages. Japan focuses on the reliability and safety of the SCMaglev, which holds the world record. France, a pioneer in the West, maintains the tradition of efficiency of the TGV and continues to export technology to countries like Spain and Morocco. Meanwhile, China, in addition to having the largest high-speed rail network on the planet, is heavily investing in maglevs of 600 km/h and even in “flying train” projects that could exceed 1,000 km/h in vacuum tubes.
The Role Of Brazil In This Scenario
Brazil is still just getting started in this sector, but it is not out of the game. Researchers at the Federal University of Rio de Janeiro (UFRJ) have developed the Maglev-Cobra, an urban prototype based on superconductors. Although it operates at low speed and on a reduced scale, it is a sign that the country seeks to participate in innovation.
Moreover, projects like the TAV Rio-São Paulo, approved in 2025 by ANTT, aim to create a conventional high-speed line connecting Brazil’s two largest metropolitan areas in just 1 hour and 30 minutes of travel. Still distant from Japanese or Chinese records, but crucial for integrating national mobility.
News And Global Trends
The future of the sector is not just about speed. Integration of modalities, sustainability, and reduction of carbon emissions are priorities. High-speed rail transportation is more efficient and cleaner than air or road transport, making it central to energy transition plans.
The trend also points to Railway 4.0, with automated control systems, advanced signaling, and embedded technologies that enhance both operation and passenger experience. In this scenario, countries that manage to balance cost, safety, and innovation will come out ahead.
Brazil may not be ready to break records of 600 km/h, but it has a unique opportunity to benefit from international experiences. While Japan and China compete at the limits of technology with magnetic levitation trains, the Brazilian challenge is more practical: reducing logistical costs, integrating regions, and providing fast and sustainable transportation.
Do you think Brazil should invest in magnetic levitation trains or focus first on conventional projects like the TAV Rio-São Paulo? In your opinion, what should be the priority for the future of mobility in the country? Join the discussion in the comments and share your views.
Trem bala foi projeto no governo dilma, ate hj tem gente recebendo salario de um projeto que nao funcionou.
Agora mais um projeto para corruptos e suas robalheiras.
Por que França? A China está anos luz à frente de todos os países com relação à trens de alta velocidade. Quanto ao Brasil, está engatinhando. Falar em “desafiar” é piada.
Ué? Por que não a França? Antes da Europa toda e depois do Japão, ela influenciou a ter TGV e trens de alta velocidade interligando toda a Europa. Em 2007, o TGV bateu o recorde de mais de 500 km por hora. A Ásia, hoje com a China, é quem brilha com trens de alta velocidade, mas por que excluir a Europa?
Quem compra um carro mira um 0km logo, penso, q o lógico seria apostar na tecnologia mais atual – Maglev.
