Year 2027, Japan prepares for the first trip of its new Maglev. The train that works by magnetic levitation runs at a speed of 505 km/h and has exceeded 600 km/h in its testing phase. It will barely take 40 minutes to travel between Tokyo and Nagoya, cities that are currently separated by more than an hour and a half of travel.
If we move it to Spanish soil, the new Maglev that is about to leave Tokyo station would link Madrid and Barcelona in 75 minutes. Today, the fastest train takes 182 minutes and work is being done to reduce travel time to less than two hours.
But all this is a dream. A nightmare, more like.
And it is that Japan has been dreaming for years with once again taking the initiative in high-speed rail worldwide. Despite being the pioneers in offering trips on what are known as “bullet trains” and demonstrating to the world in 1964 that they were decades ahead of any competitor, China has surpassed them.
A project aims to return them to the top. It is the Chuo Shinkansen line operated by a Maglev. But that project is taking hold and, at the moment, things are not looking too good.
A decade of delay and shovelfuls of money
When in 2015 the Maglev exceeded 600 km/h We thought that today we would travel by train much faster than we do. Japan then presented a seven-car prototype known as the L0 Series. It was one of the first steps to connect Tokyo and Nagoya in just 40 minutes.
He calendar projected the dream described above. In 2027, Japan would have a line operated by trains capable of reaching 505 km/h. It would be a punch on the table on a board, that of high speed, which China dominates right now. The neighboring country and great rival has managed to establish itself as the place where the trains travel the fastest, move more people and They have more kilometers of roads available.
But all these plans have been delayed and the new date points to 2036. They explain in the specialized media Japanism that the Chuo Shinkansen was designed as a fast route to link the large cities located on the Pacific coast. Currently, Tokyo, Nagoya and Osaka are already linked by the Tokaido Shinkansen, but this new line would serve to decongest roads that circulate at their limits and, at the same time, offer the fastest route possible. So much so that Tokyo and Osaka, today separated by a trip of at least 202 minutes, would become connected in just 75 minutes. That is, an hour and a quarter.
This alternative obviously requires the construction of an entire railway infrastructure that is encountering a multitude of problems. One of the big secrets why trains in Japan are so fast and punctual is that they use different infrastructure for their high-speed trains and conventional ones. With the Chuo Shinkansen it would be even more necessary since the train works by magnetic levitation.
The Maglev is an old Japanese railway dream that has its roots in the 70s when research began on whether a train could operate using magnetic levitation. The idea is that the train “floats” on the tracks traveling at a very high speed, held by powerful magnets. This way friction against the tracks is eliminated and the ride should be smoother and quieter. Obviously, this prevents the current roads from being reused.
To carry out this new infrastructure, Japan has proposed launching its trains underground for about 250 kilometers. Tokyo and Nagoya are separated by 286 kilometers and the project involves burying 90% of the route. And to reduce travel times, the train would go underground in the interior of the country, instead of continuing near the coast like the current Tokaido Shinkansen.
High-speed trains have a problem: tunnels. The speed of trains in Japan is limited by the numerous holes that the country has had to make in its mountains to carry out its high-speed lines. With each entry into a tunnel there is a change in pressure that generates discomfort for passengers and enormous noise outside, as well as challenges for the movement of the train itself.
The idea with Maglev is to eliminate these entrances and exits with a train that almost always runs underground. In this way, it can also work in vacuum conditions, which reduces the energy needed to reach speeds of more than 500 km/h.
This idea has faced countless problems, they explain in Japanism. The project began to take shape in 2011 but has experienced constant delays and setbacks. First there was an important political struggle to decide what the final itinerary of the line was and it was not until 2015 when the ground began to be excavated.
The problem is that the new tracks circulate, in some sections, next to current high-speed tracks. They explain in the middle that in the Shinagawa area the conventional train tracks are being replaced by magnetic levitation sections but that they can only advance 12 meters a day because there are only four hours of work left free, which is the interval between the last train of the day and the first of the next day.
All this, added to the fights with the land owners and the technical difficulties, has increased the cost of the project. It was estimated that the line between Tokyo and Osaka would cost 9 billion Japanese yen, of which 5.52 billion yen would have to be spent between Tokyo and Nagoya. However, cost overruns have skyrocketed the final figure and in 2025 JR Central, in charge of the project, already estimated the cost of this last section in 11 trillion yen.
All these cost overruns and technical problems (barely 2% of traffic will move on land, 86% of the time will travel underground and the rest on viaducts and bridges) have caused interruptions in construction and, as we have seen, an increase in the cost of the project that Nikkei Asia amounted to more than 23,000 million euros last October. With these latest calculations, it is estimated that more than 59,000 million euros will have been invested at the end of the project.
And that is if, finally, there are no more changes and Japan wakes up from its nightmare in 2036.
