Spain is committed to connecting Madrid and Barcelona at 350 km/h. And you have already taken the first step to achieve it

by

Madrid and Barcelona linked by a train capable of reaching 350 km/h. Just when the journey between the two largest Spanish cities has become a Russian roulette if your goal is to arrive on time. And just where the Renfe trains are having the most problems fulfilling what is expected. However, the Government is determined to increase the maximum speed of the line. And you have already taken the first step. At 350 km/h. In November 2025Óscar Puente, Minister of Transport, presented one of his star projects: linking Madrid and Barcelona with a train that travels at a maximum of 350 km/h. The final objective is to be able to travel between both cities in less than 120 minutes when it is now necessary to spend at least 182 minutes. As long as everything works correctly, of course. To reduce the trip by one hour two interventions are necessary for which the necessary papers have already begun to be moved. One of them is the construction of two new stations, one in Parla (close to Madrid) and another in El Prat de Llobregat (close to Barcelona). The objective is to decongest the traffic that currently passes through Madrid and offer a variant of exit and entry to Barcelona. The other intervention would be applied to the infrastructure itself and, it seems, will be the first to be carried out. A first step. The Ministry of Transport has confirmed which has already awarded a first supply batch of overhead traverses for the Madrid-Barcelona high-speed line. A 112 million euro contract that is key for trains to reach 350 km/h top speed. These first air traverses will be installed in four sections: Mejorada del Campo-Brihuega (232,400 units), Brihuega-Alcolea (143,150 units), Alcolea-Ariza (166,250 units) and Ariza-Calatayud (138,600 units). In addition, some maintenance tasks have been awarded “such as the renewal of the seat plates for sleepers (elements that ensure the fixing of the rail to the sleeper).” Finally, the Ministry of Transport points out that “treatment and improvement actions are being carried out on two viaducts on the Guadalajara-Calatayud section of the Madrid-Barcelona high-speed rail line, Benamira and Río Blanco, both in the province of Soria.” A physical question When the train exceeds 300 km/hthe aerodynamic load on the underside of the trains increases. This load is generated by turbulence under the train car, “gluing” it to the track. The more load, the more energy the train has to use to maintain speed. If the train releases that aerodynamic load a little, it does not need as much energy and it is easier for it to reach the desired top speed. It is the same case as a Formula 1. The car is interested in having a lot of downforce on a circuit with many curves because it will be able to go through them faster. However, it will penalize on the straight because the top speed will be lower. On the contrary, if the circuit has few corners and many long straights, you are interested in low downforce to “fly” as fast as possible. But the car will be more unstable when cornering. Furthermore, the Ministry of Transport explains that the ‘ballast flight’ must be added. This is the vibration of the stones, the ballast, when the train exceeds 300 km/h. At that speed it is critical because the turbulence raises these stones and produces constant collisions against the undercarriage and increases the risk of them being thrown and falling on the tracks and sleepers, generating potholes and vibrations. The air traverses. Since the project was presented, the Ministry of Transport has indicated that the aerocrosses are key to being able to guarantee speeds greater than 300 km/h on the route. But, What are aerocrosses? The aerocrosses are born from an Adif project which has been working on for more than a decade. Its design is very similar to current sleepers at first glance, but it has a rounded design that reduces the turbulence generated under the trains and, with it, the pressures that increase the aerodynamic load and ballast flight. According to his calculations: Reduces the aerodynamic load in the space immediately above the ballast bed by 21%. The design allows increasing the distance between the ballast level and the upper face of the sleeper. It has no higher manufacturing or handling costs (they are still molds). And most importantly: the aerodynamic load generated by a train at 330 km/h on a track with current sleepers is equivalent to that generated by the same train at 370 km/h, but with aero sleepers. In a delicate moment. He Adamuz accident in Córdoba led to the machinists to lift their foot on the line and Adif ended up lifting temporary restrictions of speed that have been happening until today while the line is being reviewed. The result is that Madrid-Barcelona will be played in the promised 182 minutes (25 minutes more than usual) is, right now, taking a chance. This has caused a good part of the passengers who used the train to travel during their work day, with many comings and goings during the day, to move back to the Aerial Bridge. The CNMC calculates that up to half a million passengers may be lost if travel times remain higher than usual. But, in addition, the Madrid-Barcelona line is where Renfe has detected the most problems with its Avrils. The vibrations on this route ended up generating cracks in the Talgo trains, designed to be used on variable gauge trackwhich gives them a competitive advantage in Madrid-Galicia. However, Renfe had to remove them from circulation upon seeing that they broke on this route that is now being renewed.

A homemade drone has just exceeded 700 km/h. And with this he has put the official record on the ropes

by

When we think of a drone, we normally imagine a device that takes off vertically, remains suspended in the air and allows us to record impossible shots quite easily. He Blackbird It’s not about that. Its objective is much more extreme: fly as fast as possible. In this race, stability in flight matters less than efficiency at high speed, and so a change in the propellers has given it a surprising boost. The official record remains in the hands of Luke Bell and Mike Bell. According to Guinness World Recordsreached an average speed of 408.60 mph, equivalent to 657.59 km/h, on December 11, 2025, with the Peregreen V4 in Cape Town. It was not their first time: Guinness points out that father and son had already achieved this same record in 2024, with 480 km/h, and in June 2025, with 580 km/h. With that bar on the table, the Blackbird attempt has a very specific reading: it does not replace the official record, but it puts it under pressure. Ben Biggs and Aidan’s drone reached 453 mph, approximately 730 km/hduring a test pass. That fact is the most striking, although it is also the one that needs the most context. For now, what we have is an unofficial demonstration with a huge figure and the question if it can be repeated under verified conditions. A record-breaking race played on the propellers Here is the nuance that separates a spectacular figure from a truly comparable measurement. On the 730 km/h pass there was a tailwind of 54.7 km/h, so the estimated airspeed was reduced to 674 km/h. On the upwind pass, the drone reached about 640 km/h. The average of the two was close to 684 km/h, and that is why that data weighs more than the maximum peak when we try to understand how far the project really went. The key is how those new propellers behave when the drone stops flying like a conventional quadcopter and starts moving like a controlled projectile. The carbon fiber blades have a high pitch angle and that allows them to be more efficient at high speed because they are more parallel to the air that the drone passes through. It is not a free advantage: on takeoff and at low speed they push worse, so the motors have to demand more from the battery in that initial phase. The other important detail is in the serrated leading edge of the blades. As they explain, this shape generates small vortices on the surface of the propeller and helps the air not to move laterally along the blade, but rather to come out backwards to push the drone. It also helps to stabilize the boundary layer, that film of air attached to the surface that influences drag. In practice, it allows working with steeper angles without the propeller losing efficiency and behaving more like a piece that removes air than one that generates thrust. The flip side of pushing a quadcopter to the limit is that problems can also arise. Blackbird lost connection at about 633 km/h, due to a combination of antenna geometry, Doppler effect and signal overload. In the second, the drone ended up damaged after a hard landing, when the batteries ran out a few meters from the ground. The official record remains that of the Peregreen V4, but the Blackbird has made it clear where the next attempt may be. The question, now, is obvious: will they call Guinness World Records to try to certify it? Images | Drone Pro Hub In Xataka | The US vetoed the largest Chinese drone manufacturer.

the sensation of jumping from the 13th floor at 100 km/h

by

With summer almost (almost) knocking on the door, it’s time to think about what to do on vacation and how to take advantage of the sun, the heat and the long days that provide light until late in the afternoon. There are those who choose the beach, the mountains, a cold beer on a terrace or, in the case of people hooked on adrenaline shots, jumping into the void from 13 stories high, without ropes or parachutes. It sounds strange, I know, but that’s precisely it. the experience featuring Verti-Go, one of the tallest water slides in Europe. Its owners assure that when descending it they are easily reached. 100 km/h. As I said: an experience suitable only for people who really like adrenaline. Who said vertigo? Spain offers many ways to cool off in summer, but few (none) like Vertigohe megaslide aquatic Aqualandia Benidorma huge water park located on the Costa Blanca. Whoever gets on it is guaranteed a dip, but first must face an experience that is not very advisable for people with vertigo or those who do not like strong emotions. Before reaching the water you must climb several dozen meters and then drop into the void and travel, in a matter of three seconds, the equivalent of a multi-story residential tower. “It’s like jumping off a 13-story building,” they assure those responsible for the park, who specify that the level of inclination exceeds 60%. Is it that big? Yes. And it comes with taking a look at your file to check it. According to Aqualandia Benidorm, the slide is 33 meters high and more than 100 m long, allowing those who slide down it to reach more than considerable speeds. Those responsible speak of more than 100 km/halthough they clarify that this information depends, among other things, on the body mass of the person jumping. To enjoy the experience you must meet certain conditions: measure at least 1.4 m and not exceed 120 kg. If you want to release adrenaline, but with a somewhat more moderate experience, the same park has a second water slide 28 meters which extends over 95 m in length. It is a smaller version located right next to its ‘big brother’, although it still far surpasses the majority of water slides in Spain. Is it new? No. Verti-Go was introduced to the world a few years ago, during summer 2013. At that time it was announced with great fanfare as one of the riskiest (and most attractive) bets of Aqualandia, a water park that also accumulates a long story. The venue opened its doors in 1985presenting itself as “the largest in Europe”, with a dozen attractions. from the park they explain which maintained that status for just over two decades, until 2008. That year opened in Tenerife Siam Park. If Verti-Go is in the news these days it is because Aqualandia has just premiered its new season. It did so on Saturday the 23rd, with more than twenty attractions that include rapids, soft slopes, a wave pool, several slides, Verti-Go, children’s areas and another highlight: Cycloneinaugurated in 2019 and, depending on the park“holds the record for the longest water roller coaster in Europe.” The truth is that it reaches a greater height than Verti-Go (36 m) and travels more than 200 m, although the average speed is much lower (60 km/h). @aqualandiabnd And if you then end up in a capsule that launches you at 100 km/h from a height of 33 meters… I won’t even tell you. 😏 Raise your hands 🙋 those who have already experienced the Verti-Go madness. 🔥 #vertigo #waterslide #giantslide #capsuleslide #aqualandia #waterpark #waterpark #waterpark #benidorm ♬ Vidrado Em Você – Dj Guuga & Mc Livinho Do you have any Verti-Go records? If you search on Google you will find a good handful of articles in which Verti-Go is referred to as “the water slide highest in Europe” or the “capsule slide fastest in the world“. The reality is more complicated. When it opened, in 2013, showed up as a unique case and the largest attraction of its kind on the entire continent. The truth is that for years in Caribe Baya park in Veneto (Italy), there is a water slide that allows you to jump from a height of 42 m. His name: Captain Spacemaker. According to the Italian venue, it is “highest in Europe” in his style. If we look further we find facilities still most surprising. In Meryal Park in Qatar, there is a slide that “reaches a height of 76.3 m.” Its name leaves little room for doubt: Vertigo. In Brazil there is also another mass to take into account, Kilimanjaro, built more than 20 years ago and offering a drop of 49.9 m. According to the Guinness Book it is “the tallest water slide”. Have they overcome it then? If we talk about water slides, Vertigo or Kilimanjaro are much higher than Verti-Go, but if we talk about Europe things are a little more complicated. The rankings They usually place the Caribe Bay structure in Italy first, because exceeds 40 meters in height. However, some media indicate that the complete structure of Verti-Go is also around those dimensions. Aqualandia itself assured in 2016 that the attraction has a 42m high. Are there more categories? Yes. The Alicante park also boasts that Verti-Go is a unique copy “capsule slide”, a label that identifies a very specific type of slide. Basically, users enter a capsule with a trapdoor in the floor that, after a brief countdown, opens to let them fall. In 2016 Aqualandia claimed that Verti-Go was “the tallest in the world.” Now keep defending which, at the very least, is “one of the tallest capsule slides.” “Only the bravest dare with this attraction suspended on a 42 m high platform, where the tower has 250 steps to its highest point, simulating the height of a 13th floor and which is accessed through an airtight and transparent capsule,” clarify the company. … Read more

While China boasts of its high-speed trains, there are others that go at 40 km/h and are just as important

by

We have spoken on many occasions about the enormous China’s railway infrastructurewith a very extensive network of high speed trains who serve this colossal country. But in parallel to this technological showcase, China also operates another network of trains that travel at less than 40 km/h, cost less than the price of a coffee and have not raised their prices for decades. And no, they are not a vestige of the past that no one has bothered to dismantle. They are perfectly functional and provide a very important service in the country. What exactly are they? They are officially known as public welfare trains, although many of the population refer to them as “slow trains for the poor.” The Chinese government maintains 81 active routes of this type throughout the country, all of them inherited from the era of Mao (Mao Zedong, who ruled the People’s Republic of China from 49 until his death in 76) and preserved as a social service. According to collect Marketplace, are trains painted in military green with a yellow stripe (the classic image of the Chinese railway before modernization) that stop at each station along the way, including small remote villages that no other transportation connects with the outside. Its prices are so low that the train itself has a sign painted on the side that identifies it as a “slow train in the fight against poverty.” How cheap are they? To give an example, the minimum fare for the train that travels 376 kilometers between the provinces of Sichuan and Yunnan is 2 yuan, which is equivalent to about 25 euro cents. The maximum, for the complete journey of more than 11 hours, is 25.5 yuan (less than 3.50 euros). According to People’s Dailythat price has not changed for more than 30 years. What are they really for? The point is that these trains not only transport passengers, they are economic, health and educational infrastructure for communities that would otherwise be isolated. People’s Daily account how some carriages incorporate notice boards with crop prices to facilitate trade between farmers and urban buyers. In several trains, rows of seats have been removed so that farmers can board with their goods (vegetables, chickens, construction materials, etc.) without restrictions. Just like account According to the Xinhua agency, these types of trains are like a mobile artery that takes villagers to the market, transports livestock and allows children to go to school in the nearest towns. Tsocial ermometer. Axi Aga has been working on train 5633 since 1996. He started as a flight attendant when passengers boarded carrying potatoes, corn flour and turnips, and could barely afford instant noodles during the journey. In 2020 explained to the portal of the Chinese State Council (SCIO) that currently sees passengers boarding who are concerned about how they are dressed, wearing traditional costumes on holidays and recording videos for social networks. “The train is like a mobile town in which I have witnessed the changes it has brought to people over the last 25 years,” he told the outlet. According to Aga, girls used to barely appear among the students. Today they represent two thirds of the students who use the train. Beyond transportation. In recent decades, these routes have evolved into something more akin to a service platform. According to People’s Dailysome trains in the north of the country already have shelves of books, study tables with plugs and school supplies for children who do their homework during the journey, with conductors who help them during breaks. They also carry hot water bottles, thermal bags and portable chargers. In winter, the carriages are kept at 20 degrees to protect passengers from the freezing cold. Furthermore, over time they have incorporated air conditioning and progressive improvements without giving up their public service mission. Why the government keeps them at a loss. They are more of a social policy strategy than a commercial one. These routes lose money, since their fares do not cover operating costs and the State subsidizes them directly. The decision to maintain them is simply territorial cohesion, that is, ensuring that the most remote and poorest areas of the country are not disconnected from the rest of China. The Global Times points out that these routes have been in operation for more than 60 years and that the national railway considers them a structural measure to combat poverty, not a residual service.

discovering the largest railway network in the world at 347 km/h

A new day dawns in Beijing. After a long (and exhausting) day at the Motor ShowToday we have a long train journey ahead of us. Today we leave Beijing to head to Wuhuthe city where the headquarters of the Chery group is located, and yes, we do it by train. I admit that I am excited: it is the first time that I have gotten on both a bullet and a Chinese train. When I ask local Chery employees about Wuhu, what it is like, they all tell me the same thing: “for you it is a huge city, but for us it is a small city.” Wuhu has four million inhabitants. Madrid, to put us in context, has 3.4 million. I imagine that living in a country of 1.4 billion inhabitants causes the dimensions of things to become distorted. I suppose that for someone from Beijing traveling to Madrid is like when we go to town. Buildings in Wuhu | Image: Xataka Wuhu is located around 1,000 kilometers south of Beijing. Specifically, between Wuhan and Shanghai. Google Maps, which is not the most reliable reference in China, shows me almost 11 hours by car. By train, the trip lasts around four and a half hours, which is more than enough time to talk a little about this other small-big city and, in the process, get to know the city more closely. chinese railway network and the experience of traveling on one of its trains. China has made leaps and bounds in its electrification, we have seen that in the two previous installments of this daily blog. Well, in the same way that the electric and hybrid car has evolved, so has its railway network. Let’s go in parts. To get into flour let’s look at some numbers. Let’s talk about Spain. Our country has 15,652 kilometers of road, of which 4,000 kilometers are high-speed (+200 km/h). It is the second most extensive high-speed network in the world. The first, indeed, is the Chinese one. And it is with an absolutely insane difference. Roads in China | Image: Xataka According to the Chinese government and according to the local Xinhua agencyChina closed last year with 165,000 kilometers of track, of which “more than 50,000 kilometers” are high-speed. In 2025 alone, Chinese railways transported a whopping 4.59 billion passengers, 6.4% more than last year. In Spain, the figure was of 177.6 million. We cannot make the direct comparison because the size of China is like 17 times that of Spain, but it helps us put into perspective how enormous this infrastructure is. And it is getting worse, because this year they intend to put 2,000 more kilometers into operation. Only in the first quarter of 2026 will Chinese railways they completed an investment in fixed assets of 20.9 billion dollars. By 2050, the country’s goal is to achieve 274,000 kilometers. Image | Xataka The body in charge of managing most railway operations is in the hands of China State Railway Group Company, a state-owned company created in 2013 after the dissolution of the Ministry of Railways. Since 2019 it has been under the umbrella of the Ministry of Finance. There are other “private” lines that connect mines with refineries, for example. The network is divided into several horizontal and vertical corridors, mostly concentrated in the east of the country where, evidently, most of the population is concentrated and where coal is produced. Only one line extends to the northwest (crossing the Gobi Desert and bordering the Taklamakan Desert) and southwest of the country (near the Tibet Plateau). A train on the way to Wuhu | Image: Xataka ​But let’s leave geography and talk about experience, because it is not only that the Chinese network is larger than the Spanish one (for whatever reason), but it is also significantly faster. And no, it is not noticeable | Image: Xataka The Spanish high speed can be up to 300 km/h, but on a line like the one from Andalusia to Madrid it is normal for trains to not exceed 250 km/h. Sections of 200 km/h are also frequent. Also, recently, there have been more aggressive speed limitations on some lines. I write this on a train that moves exactly at 347 km/h and I must admit that because I have seen the figure on a screen, otherwise I would not have known. I don’t know if it will be the same on all trains, but the experience on this one has been exquisite. The train, despite going 50% fast, vibrates much less than the trains I am used to taking in Spain. I think the video speaks for itself. This speed, which has remained relatively constant throughout the trip, allows us to get from Beijing to Wuhu in about four and a half hours. The train has made some stops of just a few minutes at certain stations, but little more. In a country of these dimensions it makes all the sense in the world to bet on the railway. Not only to transport people, that too, but for the transport of goods. If we have discovered something these days it is that China has a competitive advantage by having all the links of the supply chain very close at hand. That, however, is of little use if the transport of goods does not accompany. It is not the case, although half. In Wuhu, where Chery was founded, the brand’s presence is much, much more evident | Image: Xataka Again, according to official Chinese government data, in 2025 alone railways moved a whopping 5.27 billion tons of freight, 2% more than the previous year. However, road and air transport remains very important when moving goods in the domestic market. At an international level, air and sea are the two great cornerstones.

The United Kingdom has a laser capable of shooting down drones flying at 650 km/h. And each shot is the same as two beers.

by

For some time now, armies have pursued an idea: weapons that fire energy instead of projectiles. Already in the Cold War was experienced with systems capable of concentrating heat at a distance, although technical limitations relegated them to tests and prototypes for years. Today, with advances in electrical generation and beam control, that ambition has begun to emerge from the laboratory, although it still entailed challenges that for a long time seemed impossible to solve. The UK seems to have solved the most important one. From the laboratory to real combat. He DragonFire program marks a turning point in the evolution of directed energy weapons, and it does so by going from technological demonstrator to embedded operating system. The United Kingdom has decided to accelerate its deployment until 2027integrating it into Type 45 destroyers and becoming the first European country from NATO in deploying a functional naval laser. There is no doubt, the movement is not only technological, but also doctrinal, because it implies changing the way in which air defense at sea is conceived, integrating new layers that do not depend on traditional ammunition. Two beers for the price of a shot. The key element of DragonFire is not only its accuracy, but rather its economy. Each shot costs just about 10 pounds (just over 11 euros) in electricity, just a couple of “pints” in a pub compared to the hundreds of thousands that a conventional interceptor missile can cost, which completely alters the balance between attack and defense. we had seen it in Ukraine and now in Iran. In a scenario where cheap drones are launched by the dozens or hundreds, responding with expensive missiles had become unsustainable, while a laser allows the pace to be maintained. without depleting critical resources. This difference makes the laser an especially attractive tool in modern conflicts where saturation is more important than sophistication. Extreme precision and new capabilities. The system has proven capable of hitting targets the size of a coin a kilometer away, maintaining the beam on moving targets until causing structural failure. More: its architecture combines multiple fiber lasers in a single high-quality beam, guided by electro-optical sensors and continuous tracking systems. Furthermore, its sustained firing capability eliminates one of the main limitations of conventional weapons: need to rechargeallowing you to take on multiple threats consecutively in a matter of seconds. The response to swarms. The rise of cheap drones and swarm attacks has put in check to traditional defense systems, designed to intercept more limited and higher value threats. DragonFire positions itself as the direct response to that change, offering an effective solution against small, fast and numerous targets without compromising missile arsenals intended for strategic threats. In this context, the laser does not replace existing systems, but rather complements themreinforcing short-range defense and freeing up resources for more complex scenarios. From sea to air and land. Beyond its naval deployment, the program aims for broader integration in ground and aerial platformswhich infers a structural change in modern weaponry. Let us think that the possibility of standardizing this type of technology in vehicles, ships or even combat fighters opens the door to a new generation of systems where energy progressively replaces to physical ammunition. Analysts recalled by Army Recognition that although there are still limitations (such as the need for line of sight, electrical power and thermal management), the advancement of DragonFire indicates that that concept before fantastic of “infinite ammunition” has ceased to be a theoretical idea and has become an operational reality in development.

more than 600 km/h on a line that has accumulated years of delays

by

In 2015, a seven-car prototype in Japan made us dream with the tremendous speeds that the trains of the future would have, with the Japanese country as the main standard bearer. The L0 Series train reached 603 km/h on the Yamanashi test line, becoming the fastest manned railway vehicle ever recorded at the time. More than a decade later, that record still standsalthough the promise of its commercial use has yet to materialize. And the line that is supposed to bring it to travelers accumulates years of delays. magnetic levitation. The L0 Series works via superconducting magnetic levitation, using powerful magnets along the track and in the train that interact to lift the vehicle on the track, completely eliminating physical contact with the tracks. Without friction, without mechanical noise, without wear, and with heart-stopping speeds. The system is known as SCMaglev and uses an electrodynamic suspension, different from that used in the Shanghai maglev. Japan National Railways began researching this type of propulsion in 1962 with a clear objective: to connect Tokyo and Osaka in one hour. They have had that dream for more than six decades. Chūō Shinkansen. This is the maglev line under construction between Tokyo and Nagoya, with plans to extend it to Osaka. The idea is that it will be established between Shinagawa and Nagoya stations, with stops in Sagamihara, Kōfu, Iida and Nakatsugawa. The line is not intended to replace the legendary Tokaido Shinkansen, but it will exist to offer travelers a much faster alternative. The line would connect Tokyo and Nagoya in 40 minutes and, later, Tokyo and Osaka in 67 minutes, at a maximum speed of 505 km/h. Today the fastest Nozomi (Japan’s fastest high-speed train service) takes around two and a half hours between the two cities. With Chūō Shinkansen, the idea is that approximately 90% of the 286-kilometer route to Nagoya passes through tunnels, instead of following the coast, as the Tokaido does. This decision is also the root of much of their problems. ORa prefecture and a river. The main obstacle was that the then governor of Shizuoka, Kawakatsu Heita, denied permission to drill one of the tunnels under the Japanese Southern Alps for environmental reasons. The argument was that the impact studies had been carried out with little rigor and that the excavations could affect the bed of the Oi River. The section in question affected just 8.9 kilometers of tunnel within Shizuoka, but it was enough to block the entire project for years. Without that section, the rest of the work could not be completed. However, the current governor of the region, Yasutomo Suzuki, authorized the geotechnical inspection prior, but the works are still in progress. A calendar full of delays. In 2024, JR Central president Shunsuke Niwa publicly ruled out opening in 2027 and targeted 2034 as the new minimum date. But the story doesn’t end there. Last October, JR Central postponed the arrival to 2035. Construction costs have already skyrocketed by more than 50% to 11 trillion yen (about 61 billion euros), according to RailTech. The section to Osaka, for its part, It would not arrive until 2037 at best. The threat from China. In July of last year, during the World High Speed ​​Congress held in Beijing, the state-owned CRRC presented a maglev prototype Designed to reach 600 km/h. The train runs on rubber wheels at low speed and switches to magnetic levitation when exceeding 150 km/h. The Asia Times shares that it will still take a long time to put it into commercial use, and that market demand, rather than technology, is the main obstacle. But there is more: the T-Flight project from the state company CASIC, which combines magnetic levitation with hyperloop-style vacuum tubes, has already reached 623 km/h in tests in 2024, with the goal of exceeding 1,000 km/h soon. China has also, for years, the only commercial maglev in the world that operates regularly: the Shanghai Maglev, which circulates at 430 km/h.

They are already trying to drive up to 150 km/h

Many of the road regulations in the countries that make up the European Union are very similar, although each country also has room for maneuver to stipulate its own laws. An example is the case of poster colors on highways and highways, there being an interesting division between countries that use green or blue for the background of these signs. In this article the protagonist is the Czech Republic, which launched a pilot project last autumn on one of its highways, the D3, allowing circulation on it up to 150 km/h under strict conditions. This makes the country the first in the European Union to take this step, not without doubts and criticism from legislators and citizens. A movement against the current. The Czech Republic seems to be going against the grain, especially considering that much of Europe is racking its brains to debate how to reduce emissions. Just like they count From Hybrids and Electrics, the Czech Government launched a pilot that allows drivers to reach 150 km/h on certain highway sections. The decision is supported by a legislative change approved in 2023 that enabled this possibility, although its implementation did not arrive until the end of September of last year. Where and how it works. According to account According to the Ministry of Transport of the Czech Republic, the section chosen for the test is a 47-kilometer section of the D3 highway, between the towns of Planá nad Lužnicí and Úsilný, near České Budějovice. Along this route, 42 variable speed signs were installed, with a total cost of around 2.2 million euros, which can show three different limits: 150 km/h when everything is in order. 130 km/h in general mode. 100 km/h when conditions get complicated. The issue is that the maximum speed does not depend on the driver, but on a centralized system managed by the National Traffic Information Center, which crosses data from weather stations, cameras and sensors in real time. According to the spokesperson of the Directorate of Roads and Highways, Jan Rýdl, for the 150 km/h limit to be enabled “it cannot rain, the road has to be dry, in winter it is not activated in any case, traffic must flow normally and there can be no accidents, works or broken down vehicles.” What makes it unique in Europe. With this measure, the Czech Republic becomes the country with the highest speed limit in the European Union, above Poland and Bulgaria, which currently top the list with 140 km/h. The only case that escapes this comparison is Germany, where some sections of the autobahn They lack a fixed limit, although this model has its origins in a very different historical tradition. Czech Transport Minister Martin Kupka pointed out in an interview with the news channel ČT24 that the pilot’s goal is to evaluate “how the increase in the limit is received among drivers and whether it causes an increase in the number of accidents.” The test has a minimum duration of six months, and the results will determine whether the model is extended to other sections. Not everyone sees it well. The decision has not been without criticism. Raising the maximum speed implies greater fuel consumption per kilometer traveled and, therefore, more emissions, something that clashes head-on with the environmental guidelines promoted by Brussels. Austria tried something similar between 2018 and 2020, when it raised the limit on the motorway between Vienna and Salzburg to 140 km/h, but backed down due to political pressure and concerns about emissions. The Netherlands, in the opposite direction, even reduced its limit during the day from 130 to 100 km/h for similar reasons. Furthermore, beyond the environmental issue, it is always worth remembering that the higher the speed, the shorter the reaction time in any circumstance and, therefore, the greater the consequences in the event of a collision. Czech authorities defend that the dynamic control of the system mitigates these risks, but not everyone shares that confidence.

Yes, the DGT has limited the maximum speed to 80 km/h and has prohibited overtaking. And there’s a good reason for that: wind.

In Spain the weather is bad. I don’t know if you had noticed but we have had rain, snow and very strong winds for a month and a half. Meteorological events that are impacting all types of sectors. Also that of mobility, where closed roads, incidents on the road and restrictions are being the general trend. If you go to your favorite social network and read that the DGT has limited the speed to 80 km/h, don’t panic. It’s normal. At 80 km/h maximum. And overtaking prohibited by order of the DGT. It is a headline that has been repeated in the last two days and has spread across social networks. Headlines that hid an essential word to understand the information: temporal. Meteorological storm, because the restrictions are due to the clash of storms that we have chained for days and weeks in the Iberian Peninsula. And temporary because the restrictions are not definitive, they are simply used to maintain safety on the road. The restrictions. One of the provinces that found the most restrictions of this type during the past weekend was Castellón. The region has had to live with an orange alert for wind and the DGT decided that the maximum speed at which one could drive on Saturday was 80 km/h on three roads in the province, where overtaking was also prohibited. The trucks They were also not allowed to circulate on the AP-7. Yesterday, Sunday, normality was recovered. These restrictions have obviously been temporary. And, effectively, the DGT can apply temporary restrictions on speed or overtaking for meteorological reasons, just as can close a road to traffic due to snow or it can be restricted to those who They drive with chains or winter tires. For security. The wind is a danger on the road and overtaking is critical when there are very high wind gusts. In particular, some are very dangerous: Screen effect: when you drive through a tunnel or infrastructure that cuts off the side wind and it disappears. At that moment, a gust of wind can move the car to one side of the road and If we are caught off guard the movement will be sharper. Overtaking: something very similar happens when we overtake a large truck or van. In this case, if we are fighting a crosswind, passing a vehicle will automatically cut off the force we receive. You have to be careful because normally we have been moving the steering wheel to the right slightly to counteract the force of the wind. By overtaking the truck, that resistance disappears and we can go against the vehicle on our right, adding that the truck or van fights not to go to the left, which can end in contact. Furthermore, when overtaking, we will again feel the screen effect described above, so we must be careful and remain attentive. Trailers: Both situations are especially dangerous if we drive a vehicle with a trailer since, in that case, the car does not receive the same forces as its rear part and, in an extreme case, movement angles that are difficult to manage can arise. What does the DGT recommend? The first thing we must do is adapt our speed to the traffic circumstances. The DGT has the power to reduce the speed of the road to 80 km/h and prohibit overtaking, but the logical and essential thing is to apply common sense and take your foot off the accelerator. Taking this into account, we must remain very attentive to resolve any gusts of wind. If this happens, you have to act gently, calmly. The DGT also recommends circulate in high gears (one lower than usual) to have a greater response from the engine if we need to get out of trouble. And remember that the more voluminous and taller a vehicle is, the more risk it has of overturning, the more complex it will be to control it and the more care we must take when overtaking it.

the AVE at 160 km/h in sections of the Madrid-Barcelona route

by

Months of notices from the train drivers, who They were traveling below the maximum speed allowed on the road, and with the images of the Adamuz train accident (Córdoba) very present, Adif has reduced the maximum speed at which you can travel on the Madrid-Barcelona high speed train to 160 km/h. This is all that has happened. What has happened? Adif reduces the speed to 160 km/h in a section of 150 kilometers of the 667 kilometers that correspond to the Madrid-Barcelona route. The measure is temporary and, they announced this morning in Chain Being Before it became official, it was done after hearing the drivers complain that there were potholes in it that reduced driving comfort. after the accident. The exceptional measure comes at a delicate moment. last sunday an Iryo train derailed on a straight line near the town of Adamuz. 20 seconds later, an Alvia train traveling in the opposite direction collided with the last carriages of the Italian train and derailed. When we write these lines, 41 deaths have been reported. Since then, the videos have multiplied in which reference is made to the excessive vibrations of the high-speed trains that circulate through our country. However, the causes of the accident are unknown and It is very likely that it will take us months to know all the details. of what happened. There has been speculation about a defective switch, a stress-fractured track and train vibrations, but nothing has been confirmed by any official source. What is happening in Madrid-Barcelona? For months now, train drivers have been reporting problems traveling at the maximum speed on the track, which in The now cut section was 300 km/h. The complaint about excessive vibrations has been reported by passengers but also by workers. “The crew members complain, the interveners complain and we write complaints, because there are areas where we are hitting boats,” a Renfe driver complains to Xataka who prefers to remain anonymous. From SEMAF (Spanish Union of Railway Machinists) have confirmed to us that the machinists have been reporting considerable deterioration on the tracks for months, to the point of traveling at a speed below that expected. The height of the controversy came when last summer some S-106 trains known as the Talgo Avril cracked. Since then, Talgo and Adif blame each other for what happened. How serious is it? From SEMAF they assure us that vibrations directly impact the running comfort and the useful life of the train components but they rule out that there is a risk of derailment for this reason. From the General Council of Industrial Engineers share this vision: “the usual vibrations are foreseen in the design of both the train and the infrastructure. High-speed railway systems work with very wide safety margins,” they assure Xataka also pointing out that the perception of small irregularities on the road or in the rolling stock are amplified when driving at high speeds. And the driver who has offered us his testimony thinks the same. “If we understand that there is a danger to traffic, we call the command posts and they take measures by putting limitations, although for months we have also been taking them by slowing down. We are the first interested parties, we want to return home,” he emphasizes. First consequence. Adif’s decision is the first significant measure taken after the accident in Adamuz (Córdoba) in which 41 people have died and in which rescue work continues. It remains to be seen if more measures of this magnitude are taken but it must be remembered that the specific reason that led to the accident remains unknown.
