In the search for a supersonic train, China tests a Maglev that will reach 4,000 km/h. The problem will be maintaining it

by

China’s conquest of the high-speed train field is impressive. In the 2008 Beijing Olympicsthe country had just 120 kilometers of high speed between Beijing and Tianjin. 17 years latermanage more high-speed kilometers than any other countrya very long distance from Spain or Japan. They are not only building kilometers to unite the entire country: they are developing technologies so that the plane is no longer necessary. As? With Maglev trains at speeds of 1,000 km/h. And a specific model, the T-Flight, which dreams of 4,000 km/h. Maglev + Hyperloop. China is one of the countries, along with Japan, that is investing a lot of money in the development of the magnetic levitation trainsor Maglev. This technology allows trains not to rest their wheels on the rails, but rather to float thanks to a series of powerful magnets and an electromagnetic field. This allows us to exceed the 250 km/h that has been set as a standard for high speed and, for example, China has the fastest Maglev in the worldone that reaches 431 km/h. It is already operational between Beijing and Shanghai, but in Japan is testing one that will exceed 600 km/h. It’s a speed that will seem slow compared to what CASIC is preparing. It stands for “China Aerospace Science and Industry Corporation,” a state-owned tactical missile company that announced the T-Flight project in August 2017. The idea? Combine magnetic levitation trains with Hyperloop-style vacuum tubes. T-Flight. In short, it is putting a Maglev in a vacuum tube, eliminating air pressure and resistance as much as possible, but there is much more. For example, the idea of CASIC is that magnetic levitation is enhanced thanks to superconductors that will raise the train up to 100 mm above the rail. Conventional Maglevs are raised by about 10 mm, and the idea is that the higher the train is, the more stability it will have at extreme speeds. On the other hand, the tube itself, with a system that extracts air from it to create a low pressure environment, reducing aerodynamic resistance to the maximum. This partial vacuum and levitation that eliminates the physical resistance of the wheel and track is what will allow unprecedented speeds to be achieved. Achievements. In 2024 they already achieved one first validated test as a world record by reaching 623 km/h, but in the summer of this year, in a low pressure environment, The train reached 650 km/h in seven seconds in its laboratory. They were strange tests, since the track was a kilometer long when the usual thing is much longer, but that also gives us a clue of what brutal which is both the acceleration and braking of the train. That is, think that, in seven seconds and in just one kilometer, the train accelerated to 650 km/h and stopped. The team’s idea is to reach 800 km/h as the top speed this year, but the ambition goes much further. Ambition. Currently, the team is in Phase 1, which is the one that aims aim that speed of 1,000 km/h. To do this, and to validate the speed in real conditions, they want to extend the test track to 60 kilometers. However, the thing does not stop there and, when the project was born, it was already said that Phase 2 and Phase 3 would have as aim 2,000 km/h (almost double the cruising speed of a traditional commercial airplane) and 4,000 km/hsupersonic speeds that would compete with the fastest planes in the world. This would allow large urban centers in China to be linked in a few minutes, leaving aside the need to take planes to cover long distances. In fact, this high speed is already showing in Europe that short flights do not make sense if we combine the waiting time at the airport with the flight itself and compare it with the comfort of access to the train. A major challenge. Now, the goal will not be easy. Maglev technology works and is proven, but what they want to achieve with this T-Flight not only complicates things because, in addition to a track, a tube must be built. And, of course, maintain it. Extending this partial vacuum over hundreds of kilometers of tube represents an enormous technical challenge because it implies that the joints must be perfectly sealed, without the cold and heat dilating them so that there are no leaks. It is estimated that a 600 km pipe requires an expansion joint every 100 meters, and each one of them represents a potential point of failure. Furthermore, at 300 km/h appreciate vibrations in the seats. Air system to reduce pressure inside the tubes Furthermore, any decompression would be catastrophic and perhaps most importantly: there is no certification standard or safety protocols for something like this. In any case, T-Flight continues to take steps at a good pace and, although it seems difficult to see it working in the short term, if a country can achieve it right now… it is China.

AEMET knows that what is coming is not just a train of storms, it is a ‘master class’ on how winter works in Spain today

by

This beginning of December comes with a train of Atlantic storms, several cold fronts in a row, snow, wind and a lot of sudden thermal changes. But it goes much further than all this: what we are going to see is a perfect example of how winter in Spain works today (in the midst of the climate crisis). What is going to happen? The quick summary is that the start of December 2025 in Spain will be marked by a very active Atlantic circulation. And that takes the form of a “squall train” that will cross the Peninsula during the first 10 days of the month. The most immediate will be a cold front that will leave abundant rains in Galicia and the Cantabrian Sea (with local accumulations of up to 50 l/m²), snow above 1000 meters and strong gusts of wind on the coast. But, as I say, it is the first of at least four. The reign of the negative NAO. We said it a few days ago, the European Weather Forecast Center pointed because the first days of the month we were going to be in negative NAO. The ‘NAO’ is the ‘North Atlantic Oscillation‘ is what meteorologists call the relentless fight between the Azores anticyclone and the Icelandic low, the two great atmospheric phenomena that govern the meteorology of the North Atlantic. When the index we use to “measure who is winning” is negative, the Azores anticyclone is weaker than normal and, for this reason, it cannot block deep Atlantic storms. The direct consequence is that they circulate further south than normal: right at our latitude. This is exactly what is happening. For this reason (and as a novelty) “squall train” is not a funny journalistic metaphor: there are four very active fronts heading towards Spain. And it goes without saying that this is good news: we are coming from very dry and irregular autumns and, despite the cushion of dammed water that we havea phenomenon of this type is going to be really good for us. It remains to be seen if we will be able to take advantage of the rainfall that will arrive. Why do I say this is “a perfect example of how it works today (in the middle of the climate crisis) winter”? Because although the pattern of “chained storms” is classic of the Atlantic winter, these dynamics are encountering a warmer basal situation: the atlantic ocean and the Mediterranean Sea is warmer (and therefore have more energy). It’s “business as usual”, but at higher speeds. In this situation, in fact, a scenario is feared for Europe in which there is less rain in summer in the Mediterranean and more episodes of extreme rain in the cold seasons. This feeling that everything is very similar to the same as always, but in a completely different way, is very strange.

The hundreds of black dots on train and car windows are not a whim: they are a shield called ‘frits’

by

Traveling by car or train means looking around the windows. You probably don’t just look at the landscape, but at all the vehicle interior elementsthe closest being the edge of those windows. A common element on the train and on the car window is a black border with a curious pattern of dots that become smaller as the rows increase. It is not paint or an aesthetic element, but something that fulfills a crucial technical function to protect the integrity of the glass. They are called ‘frit band‘ either ‘frits‘, and it is one of the most important passive safety elements that these vehicles have. The Science of Car Window Blackheads Although it seems like it, these dots are not paint: they are ceramics baked at very high temperatures, which fuses with glass during manufacturing of the same. He process It is most curious, since first the still hot black ceramic paste is applied to the edges of the glass, and then it is baked together with the glass in the tempering and bending process. In Xataka In 2001, Renault launched a car ahead of its time: it was a miserable failure that now has another chance It is a structural element of glass and this process involves a permanent bond that does not wear over time. The dot pattern motif, known as “gradient matrix”it is not a whim either, but a solution to something that could spontaneously break the car window. Black glass absorbs much more heat than clear glass, and this is something you can easily check on a sunny day: the black band will be hotter than the rest of the glass. When the temperature is extreme, and on trips where the moon can being hit by small stonesif there were an abrupt temperature transition between the black border and the transparent area, stress points would be created that could cause cracks. That’s why they pulled out that gradient that works like a processor heatsink: creates a thermal transition zone which distributes heat more evenly. It is something that provides protection to the glass, but they serve something else: to help the bond between the chassis and the glass. On the perimeter of the crystals there is glue that joins the elements, and the ‘frits’ have a rougher texture that allows a better adhesion from glass to chassis. Also, being black, they protect the glue against ultraviolet rays, maximizing its durability and the security of the union of the components. A detail from Jeep, which introduced an Easter egg in these frits In the end, what might seem like a simple aesthetic element fulfills an important safety function. In the train, this adhesion and thermal dissipation, and in the car, added to the above, greater resistance of the moon to shocks. In some cars it has been used to place a nod, and the fact that they are circles and not another geometric element has an aesthetic part, but also functional because it makes us overlook them while driving. It is one more example of all that everyday technology that surrounds us and that perhaps we always wonder if it would have some function, but once that initial curiosity passes, we forget to look.

Saudi Arabia is looking for someone to build its new high-speed train. And a battalion of Spanish giants are going to compete

by

Saudi Arabia has put one of the most ambitious railway projects in the Middle East on the table, and the response from the global industry has been especially strong: 145 international companies have officially expressed their interest for participating in the new high-speed line that will connect Riyadh with Qiddiya, a newly created city dedicated to tourism and entertainment. And as it could not be otherwise, among the candidates stand out several Spanish companies with great experience when it comes to cooperating in Saudi projects. What exactly is this project. It is about the Qiddiya High-Speed ​​Railalso known as Q-Express, a high-speed rail line that will link King Salman International Airport and the King Abdullah Financial District (KAFD) in Riyadh with Qiddiya City, according to the Royal Commission for Riyadh City (RCRC). The trains will reach speeds of up to 250 km/h and the intention is for them to complete the journey in about 30 minutes. Qiddiya is one of Saudi Arabia’s five official mass tourism-oriented gigaprojects and is expected to occupy some 376 square kilometers. The city will include 12 amusement parksa Formula 1 circuit and is projected to house 500,000 inhabitants. Several Spanish companies interested. Between companies that have shown interest There are Spanish names with weight in the railway sector. CAF and Talgo appear in the category of manufacturers of rolling stock and railway systems, where they compete with giants such as Alstom, Siemens Mobility, Hitachi Rail or Stadler Rail. Renfe and Alsa, for their part, are among the 12 interested railway operators, along with Deutsche Bahn, Ferrovie dello Stato Italiane or SNCF. In construction, FCC Construction and Copasa stand out, while in technical consulting, Sener, Ayesa, Idom and Typsa are present, competing with international firms such as Aecom, AtkinsRéalis or Systra. Previous experience in the country. Several of these Spanish companies are not new to Saudi Arabia. Some were part of the consortium that developed the well-known AVE to Mecca (Haramain train), which connects the holy cities of Mecca and Medina. Currently, Renfe operates precisely that high-speed line. The president of the company, Álvaro Fernández de Heredia, visited Saudi Arabia just a few weeks ago to participate in an international railway meeting, and where reaffirmed the company’s commitment to collaborate with Saudi Arabia Railways on new projects. For its part, Alsa It already has a guaranteed presence in Qiddiya: a €500 million contract was recently awarded to operate the city’s future buses. Fierce world-class competition. He complete list of interested parties gives clues to the magnitude of the project. The 68 main contractors include companies from China (eight companies, including China Railway Construction Corporation and Aviation Industry Corporation of China), Turkey (with Gülermak, Kalyon or Yapı Merkezi), Italy (Webuild and Saipem), South Korea (Hyundai Engineering and Samsung C&T), France (Bouygues Travaux Publics), India (Larsen & Toubro) and Portugal (Mota-Engil), among other countries. 16 capital investors and 23 design and project management consultancies have also shown interest. How it is going to develop. The project will be executed under a public-private partnership model (PPP), as announced by the RCRC in collaboration with the National Center for Privatization and the QIC. The registration period where companies could show interest in the project opened on September 12 and closed on October 12. Although it was initially planned to be developed under a conventional model, the Saudi authorities finally opted for a public-private collaboration scheme. What comes next. The development includes two phases. The first will connect Qiddiya with KAFD and King Khalid International Airport. The second phase will extend from a development known as North Pole, which includes the Public Investment Fund’s two-kilometre-high tower, to New Murabba, King Salman Park, central Riyadh and the Industrial City south of Riyadh. In addition, the 65-kilometer Riyadh metro line 7 will also connect the capital with Qiddiya City in the future. With so many high-level companies competing for this megaproject, now it’s time to find out which consortiums manage to position themselves as favorites in the bidding.

The longest train in history was born in 2001 and since then no one has surpassed it

by

The train is the backbone of many countries. In Europe we know it wellin Latin America is catching up and the China and Japan current ones would not be understood without it. Another country where it is vital is Australia, although more than for the movement of the population, for the transport of goods. And, in 2001, in the heart of Western Australia, the BHP Iron Ore It made history by becoming the longest train in the world. More than seven kilometers long that have not yet been equaled. Necessary. One of the most powerful industries in Australia is mining, so much so that there are even mining influencers that recruit workers from any country. In the late 90s, mining companies faced a challenge: an increasing amount of mineral had to be transported from the source to the export ports. It was a challenge because logistics costs had to be kept under control so that prices did not skyrocket. Traditionally, we would have chosen to put more trains into operation, but it would not be efficient because we would have to pay for more fuel, for the use of the infrastructure and the salaries of a larger crew. Come into play BHPthe Australian giant that is one of the largest mining companies in the world, with an idea: what if we set up a huge train to load iron? This is how the Iron Ore train was born. The BHP Iron Ore train. Its dimensions were extraordinary: a convoy made up of 682 wagons, 5,648 wheels, a loaded weight of almost 100,000 tons and a length of 7,353 kilometers. Imagine 22 Eiffel Towers lying down and aligned, like this. To pull such a monster, eight locomotives GE AC6000CW (each with 6,000 HP) with 16-cylinder engines were distributed throughout the vehicle. Apart from the front, the rest were within a kilometer of each other and managed to complete a 275 kilometer Yandi journey, with a cargo of Newman mines, to Port Hedland in just ten hours. The pace was slow, yes, but the important thing about this was not It was the Guinness record that he achieved, but the proof of a technology called Distributed Power. Distributed Power. This was BHP’s goal, to prove that the technology worked. And it basically consists of what we have said: distributing the locomotives along the train instead of concentrating them in the front so that the traction and braking force is greater, more uniform and, also, more efficient. Everything worked like a Swiss clock thanks to great precision and harmony between the locomotives, which were controlled by a single driver in the front system. It’s long, and there’s no train If Distributed Power was the technology, the control system was the LOCOTROL. The leading locomotive communicated with the remote ones through a radio frequency system that synchronized all acceleration and braking operations. This allowed lateral forces and friction to be drastically reduced when cornering, which reduced both wheel wear and the risk of derailment and, in turn, it is estimated that between 4 and 6% less fuel was consumed. Pilbara. The BHP Iron Ore was a technical prodigy that set the record for the longest train in the world in 2001, but if you are a train enthusiast, don’t pack your bags yet to see it in action: it was a one-time event, so much so that there is very little material about it. Once the technology was proven, what BHP did was apply it to smaller trains. The Pilbara is the region in which much of its operations are concentrated, and what the company currently operates are several regular trains with formations of about four locomotives with about 270 carriages. It is still impressive, since the length of these trains is close to three kilometers and they have a loaded weight of about 40,000 tons. The company’s next steps are to electrify these trains to reduce emissions, and one trick will be to use regenerative braking to recharge the batteries in sloped areas. It is something that other companies are also testing in the country. Similar attempts. Thus, the BHP Iron Ore was a prodigy, but also something unique that has not been matched, not even close, more than 20 years after its launch for that test. In August this year, Indian Railways commissioned the Rudrastraa 354-car, 4.5-kilometer-long train powered by seven locomotives (two at the front and one every 59 cars). And in Europe, tests are also being carried out with distributed power trains, but for kilometer and a half trains. In the end, they are all very far from the Iron Ore both in length and weight, but beyond the record in 2001 it was shown that this distributed power technology was a solution for trains longer than conventional ones. We’ll see if at some point someone needs to create a longer train, but it seems complicated.

The EU wants to connect Madrid and Paris by train, in six hours and by 2035. Or in 2042. Or maybe never

by

The European Commission has approved an ambitious Action Plan for the high-speed railway that aims to triple the European network, going from the current 12,000 kilometers to 36,000 kilometers before 2040. The objective is to turn the train into a real alternative to the plane for medium-distance journeys, drastically reducing travel times between the main capitals of the continent. And Spain is going to have an important role. What changes for Spain. The plan directly affects our country with two priority connections: Madrid-Lisbon in three hours (compared to more than eight currently) and Madrid-Paris in six hours (instead of the more than twelve that are needed now). From Bilbao you can reach Lisbon in less than six hours passing through the capital. The proposal contemplates that these improvements be operational in 2035although the corridor with France raises more doubts than the plan to join with Lisbon. Why it is important. Currently, the 12,000 kilometers of European high speed are mainly concentrated in Spain, France, Italy and Germany, while the east and center of the continent remain poorly connected. Just like points out Commissioner for Sustainable Transport, Apostolos Tzitzikostas, “Central and Eastern Europe remains woefully poorly connected.” Spain, with almost 4,000 operational kilometers, is European leader in high-speed infrastructure, only behind China globally. The money problem. Complete the planned network by 2040 will cost about 345,000 million euros. If we also want trains to run well above 250 kilometers per hour, the figure shoots up to 546 billion until 2050, according to Brussels. The organization admits that public financing it won’t be enough and seeks to attract private investment, in addition to loans from the European Investment Bank (EIB) and the national public bank (ICO in Spain). The idea is that in 2026 an agreement will be negotiated between Member States, financial institutions and other organizations and companies to settle the investment issue. Between the lines. Although the plan sounds ambitious, Brussels recognizes that it is very late: In 2020, the goal of doubling the network by 2030 was set, but by 2023 it had only grown by 17%. France, key to connecting Madrid with Paris, maintains a more pessimistic calendar than Brussels and does not see the connection as feasible until 2042. The Spanish minister himself Óscar Puente has recognized that the direct connection with Paris “will not arrive next year”. Tzitzikostas has announced who works intensely with the ministers of Spain and France to “overcome border bottlenecks.” The effect on airlines. A Madrid-Paris flight lasts just over two hours, but adding waiting times, boarding and transfers from airports, it is close to the six hours that the direct train to the city center would take. Spain and France short flights have already been banned with a rail alternative of less than two and a half hours. In addition, the EU obliges airlines to use at least 70% green fuels by 2050, starting with 2% this year, which will make flights more expensive. And now what. The plan is certainly not written in stone and the roadmap will depend on the political will of each country and the ability to attract private investment. Spain is well positioned to take advantage of these funds, since according to the media Expansión, It has 700 kilometers under construction and another 700 projected that will take the network above 5,000 kilometers between 2030 and 2032. The Commission also promises a new ticket strategy in 2026 to “make it easier for passengers to book multimodal tickets” and a full liberalization of the sector in 2040, which should reduce prices.

The Japanese Shinkansen was the fastest train in the world until China defeated it. The reason: the “piston effect”

by

In a very summary way, the piston in a four stroke engine It is responsible for moving the air inside to compress it and facilitate the burning or explosion of the fuel or to push it out of the combustion chamber. That is, it is dedicated to pushing the air up or down. Now imagine a train arriving in a tunnel at more than 300 km/h. Suddenly, the train goes from being outside to moving the air inside the tunnel. To push it to the bottom. Your movement It would be very similar to that of a piston. The train moves in a straight line and around it the tunnel would behave like a combustion chamber. That doesn’t seem like a problem. It doesn’t seem like it if we think that the air is simply pushed to the outlet where it is released without further problem. It’s also not a problem if your high-speed lines run over a bridge more than 100 kilometers long. But if you are a mountainous country and you have made the railway your star medium to move millions of people hundreds of kilometers an hour. Yes, you have a problem. Because the piston effect is pure physics and solving it to gain speed is not being easy. When they were the best In 1964, while Spain began to open up to the world, Abebe Bikila won his second Olympic Marathon in the streets of Tokyo. He did it wearing Puma Osaka shoes.nothing to do with the famous 42,195 meters that he covered barefoot in Rome to win four years before. We do not know if Bikila took that first Shinkansen that linked the cities Tokyo and, precisely, Osaka. The bullet train had begun to operate in Japan that same year, promoted by the Olympic Games in the Japanese capital. Then, the two cities were linked by a train that reached peaks of 210km/hbecoming the first high-speed line in the world. More than 60 years later, Japan is no longer the country with the highest number of high-speed kilometers of the world. Today it is China. It makes sense, taking into account that the country is huge, so if this means of transportation were promoted, sooner or later they would surpass their neighbors. Spain, by the way, also surpassed Japan in this area years ago. But it is very likely that something else has hurt Japan more. China is making the bullet train its flag. Its latest advances with the maglev, which levitates thanks to very powerful magnets to avoid friction with the track, has reached a combined speed of 896 km/h at the intersection of two CR450 trains. The problem for Japan is that China has a lot of money. And if it is necessary to build eight of the 10 longest bridges in the world to solve geographical accidents, they get to work. Japan has to deal with a lot of mountains and a more traditional system: tunnels. And that when you want to make a train pass at very high speed is quite a problem. When a train fully crosses the threshold of a tunnel, what is known as piston effecta problem that prevents increasing the walking speed further. The consequences are as simple as they are serious: loud explosions, breakage of equipment… and the eardrums of passengers. Upon entering the tunnel, the air is compressed and the movement of the train moves it towards the exit. However, some of that air rebounds and generates pressure changes that can be especially painful for passengers, even affecting their middle ear. When moving outside, a pressure wave is created that moves at the speed of sound and when the train leaves the tunnel, a shock wave and a sound explosion are created that, it is calculated, can be heard 400 meters away. It is known as tunnel boom. Japan is now experiencing a problem carried over from the past. Their trains are wider than the European ones but their tunnels are narrower. This was to reduce infrastructure costs but also to run less risk of landslides in the event of an earthquake. At first this was not a problem but when the speed of the trains increased they realized that they could not continue moving. In China, trains also use wide tracks like their neighbors but since they do not preserve inherited structuresthe new tunnels built are wider. This reduces the void effect produced with the entry of the train into the tunnel and, therefore, mitigates the problems for passengers. Furthermore, as less resistance is generated when the train passes, energy expenditure is also reduced. The solution for the Japanese is not simple. On the Tokaido Shinkansen, the first high-speed line (the one that connects Tokyo with Osaka), 13% of total kilometers They run inside tunnels. But the Sanyo Shinkansen line runs through tunnels half of the time. and he Hokkaido Shinkansen which is under construction (this line is only partially open) contemplates the roofing of 80% of the layout. The most effective solution that has been found to the problem is to produce trains with a very long and sharp nose. The aerodynamics tries to imitate the beak of the Kingfisher that can dive into the water generating minimal splashes. Following the same concept, the longer and sharper the nose of the train, the less resistance the train encounters at the entrance and the more gradually the pressure wave is generated. The other solution has been expand the section of the tunnel at its entrance. The “door” is wider and also has side openings that allow part of the air to escape. air moved by the train. This escape route generates a lower pressure wave, allowing the train not to cause unwanted discomfort to passengers and to travel faster. It has even been thought of hermetic trains with controlled pressure. During its tests, Japan continues to search for trains that can reach a top speed of 400 km/h. However, the structures inherited from … Read more

Saudi Arabia has insisted on connecting its two seas by train. And to achieve this it has been placed in the hands of a Spanish company

by

Saudi Arabia has launched one of the most ambitious railway projects in the Middle East: the “Landbridge” or “Land Bridge”, a $7 billion high-speed network that will connect the Red Sea to the Persian Gulf. The infrastructure will link Jeddah to Dammam via Riyadh, covering nearly 1,500 kilometers with the aim of completely transforming transport and commerce in the Arabian Peninsula. A strategic corridor for goods and passengers. The project will reduce travel time between Riyadh and Jeddah from around 12 hours by car to less than 4 hours by train. But the goal is for the project to go beyond just transporting passengers, as it is also designed to turn the kingdom into a key logistics hub in the region, connecting large industrial ports such as King Abdullah Port and Yanbu with urban centers and airports. According to Saudi authoritiesthe Landbridge could generate savings of $4.2 billion annually in transportation costs and create up to 200,000 jobs in related sectors. Vision 2030. This megaproject is a centerpiece of Vision 2030the strategic plan with which Saudi Arabia seeks to diversify its economy and reduce its dependence on oil. The Saudi Railways (SAR) company intends to expand the country’s railway network from the current 5,300 kilometers up to more than 8,000. As part of this modernization, SAR has ordered 15 new trains capable of reaching speeds of up to 200 kilometers per hour and even hydrogen-powered models. Spanish participation in the project. The Landbridge is being developed by the Saudi China Landbridge Consortium, a partnership between Saudi Arabia Railways and China Civil Engineering Construction Company, with local support from Al-Ayuni Contracting. Between the international companies involved The Spanish company Sener stands out, which was selected in December 2023 along with Hill International (USA) and Italferr (Italy) to provide project management services. Firms such as Systra, Thales, WSP and other specialized consulting firms also participate. A project with a long history and new Chinese momentum. Although the Landbridge It was initially announced in 2004 and paused in 2010, gained new momentum after the visit of Chinese President Xi Jinping in 2022, when both countries committed to accelerate its execution. Chinese investment in Saudi Arabia has grown significantly: in 2024, the stock of direct investment reached 8.2 billion dollarsup 29% from 2023. China has become the largest source of greenfield investment in the kingdom, with commitments worth $16.8 billion in energy, manufacturing and logistics. Railway enthusiasm. Only in the second quarter of 2025, more than 2.6 million passengers They used Saudi trains, according to Okaz media. After the completion of the Landbridge, Saudi Arabia will have made a qualitative leap in its railway network and logistics capacity, so it remains to be seen how the process ends up developing and if it really ends up being a ‘miracle of the desert’.

On June 27, China inaugurated the Chongqing East Railway Station, officially the largest railway terminal on the planet. With 1.22 million square metersThe equivalent of 170 football fields, this colossus is five times the size of New York’s iconic Grand Central. The project cost around 6.7 billion euros to materialize. In addition to its magnitude, this megastructure also has a series of very interesting characteristics that we are going to tell you about below. A titanic project in record time. Work officially began in November 2018, but satellite images shared by China Perspective on social networks show how between 2023 and 2025 the project went from being a vacant lot to a fully functional station. In fact, before work began in 2018, the area was a complete valley. The terminal opened to the public last June and already moves up to 16,000 passengers per hour.

Located in the Nan’an district, on the outskirts of Chongqing (a megacity in southwest China), the station has 15 platforms and 29 tracks. It is designed like a central axis within the national railway network known as “Ocho Verticales y Ocho Horizontales”, which connects the western and eastern regions of the country. From here, travelers can reach Beijing, Shanghai or Guangzhou in just six or eight hours. It also serves as a gateway to cities such as Chengdu, Wuhan or Kunming in times ranging from one to three hours. Image: Reddit Design inspired by the region. Unlike some of the stations we have in Europe, with a somewhat more austere design, Chongqing East boasts an aesthetic with cultural identityas well as functionality. The columns imitate the huangjue trees, typical of the area; the vents are shaped like flowers, and the welcome signs are designed like bamboo scrolls. Its glass ceiling also stands out, offering a good amount of natural light to the main room. A model of urban development. The station environment is conceived as a transit-oriented development zone, which will include hotels, offices, shopping centers and cultural facilities. In this way, the extensive land that existed before has now not only become a large station, but a whole new urban district. A way of doing things already classic in China. What’s coming Chongqing East is not finished, as it is only the beginning of an even more ambitious railway network. High-speed lines such as Zhengyu and Yukun are under construction and will further reinforce the station’s role as a continental hub. China has been showing us for decades how efficient its mega-constructions are, which go from record to record, as in the case of this station.

The countries with the most kilometers of high-speed train, displayed in a graph with a brutal dominator: China

by

The train is the backbone of many countries. For centuries it has been key to mobility in Europe, in Japan it is essential, China has experienced a railway revolution and even the United States or Latin America begin to bet on passenger mobility by train. However, it is one thing to have a railway and quite another to have a rich high-speed network. And this graph shows the countries with the most kilometers of high-speed trains and their plans for the future. China, undisputed queen. The Olympics They are an event in which countries “sell” themselves to the worldbut in the case of China, it involved a profound renovation of its infrastructure. It was in 2008 when China launched its high-speed railway line: barely 120 kilometers between Beijing and Taijin, and 17 years later, it is the country with the most kilometers of high-speed lines in operation. According to the data of World Population Review and as we can see in the graph prepared by Visual CapitalistChina has more than 40,000 kilometers of tracks on which its trains go at 250 km/h or more. They have another 12,800 kilometers under construction and more than 11,000 planned. In total, some 64,000 kilometers of high-speed rail. In addition, they are moving forward to make their network the highest speed thanks to the maglev advancesmagnetic trains, with tracks that already link cities like Beijing and Shanghai to speeds of more than 430 kilometers per hour. And it is this network that is putting the airlines in check. Spain and Japan. The train is vital in a country as huge as China and the numbers speak for themselves, but there are two other countries that, without being the ones with the most kilometers in total (operational, under construction and planned), complete the podium of those with the most high-speed kilometers currently operating. There are no surprises here. Spain has a total of 5,632 kilometers of high speed, of which more than 3,700 are already operational, followed by China the country with the most kilometers of high speed currently holds. There are another 1,040 kilometers under construction and another 862 kilometers planned. For its part, Japan, another example when we talk about fast trainshas a total of 3,700 kilometers divided into 3,050 operational kilometers, 402 under construction and 193 planned. Promises, promises. At a time when the train is emerging as the alternative to international flights, especially to low cost and among short-distance points, it is striking that, in reality, there are no more countries with high-speed lines. In Europe, apart from Spain, France, Germany, Sweden, Finland or Italy, they have hundreds of operational kilometers, but outside of the ‘Old Continent’ and cases like South Korea, things are very different. For example, India. It is the second country in the graph, but of the 8,000 total kilometers, only 508 eare under construction and the remaining 7,400 are planned. They do not have high speed, and the same thing happens in Egypt (with 3,400 kilometers planned), Australia (1,700 planned) and European countries such as Latvia, Estonia, Norway or the Czech Republic: all with plans to create high-speed lines, but not one operational kilometer. America. And if in China the train is essential due to its dimensionson the American continent we should think that things are the same. And no, not at all. The United States, a gigantic country, has only 735 kilometers of high speed, 273 under construction and almost 5,000 planned, but nothing more. Spain tried to bring the AVE to the North American country and there are demands for high-speed trains to expand, but their internal mobility continues to have the plane as the protagonist. Canada has 1,500 kilometers planned and not one kilometer built, Mexico is in the same situation with 210 kilometers on the table, Brazil the same with 510 kilometers planned and Argentina does not even appear on the graph. But, although high speed is complicated on the continent, the truth is that there are many plans to expand the railway network, even creating international trains that go from one ocean to another, like the one planned between Brazil and Peru. And who is behind many of these projects? Well, who has gained experience at a forced pace in recent years ‘pulling’ thousands of kilometers of tracks: China.
