Throughout history, travel by train was not so popular because of the relative low speeds the trains moved. The path was slow, lengthy, with frequent delays, and therefore less popular. Nowadays, the situation is completely different. Everywhere in the world super-fast trains (so-called “bullet”) are being built. Trains, due to their speed and time of arrival (from one destination to another), are dangerously competing for air travel. In the development of new trains and railway infrastructure of the future, more and more are invested for better ticket prices, compared to the plane trip. Unusually, fast trains feature a specific aerodynamic design (necessary to combat air resistance) and high comfort levels (because they work on a magnetic levitation system-maglev).
Below you will find some of the interesting facts about the train around the world.
1. Panorama trains in Switzerland – Approximately seven hours one can travel through one of the most beautiful mountain passes in the world, in Switzerland, by train called Glacier Express. This train is the “slowest train” in the world. There is a good reason for this slow pace: the train runs through the Alps, traveling 170 kilometers from Zermatt to St. Moritza, crossing over 291 bridges and navigating through 91 tunnels. https://www.youtube.com/watch?v=bEBjV_u4J-o
The trains are equipped with modern dining areas and large windows to see the spectacular scenery. The first and second classes on the train have panoramic sealed windows all the way to the top. You do not have to travel alone with the Glacier Express, if you want to enjoy the scenery of this route. On the same line, there are regular train lines. Even though they do not offer panoramic windows and the same level of comfort, you can still admire the pristine Swiss nature.

2. The Vatican has the shortest railway line in the world. It is 300m long and connects the railway station next to St. Peter’s Basilica with the Italian railway station. Opened back in 1934, the Vatican railway line stretches only 1.3 kilometers and connects the only station in the Vatican with the railway station in Rome, right outside the Vatican walls. The line has once served as a pope transport, but in the last few years, it is most commonly imported supplies from Italy to the Vatican. The almost forgotten line is another of the secrets of the Vatican, which has been discovered all over the world. In 2016 – the first time in history, the railroad is open to tourists. From September 2015, at the initiative of Pope Francis, the train connects the Vatican with the papal summer residence in Castel Gandolf. The full day ticket includes the entrance to the Vatican Museums and Gardens. The train after the Vatican station passes the viaduct leading to the Roman side of the wall, so you are for some three hundred meters in the other state. The train continues the journey through the Italian romantic villages and fields until it reaches Lake Albano, near Castel Gandolf. After enjoying the carefully kept and well-kept gardens of Castel Gandolf, before returning by train directly to the Vatican, nearby you can get some refreshments . For a small Vatican train journey, it is necessary to announce it in advance, because interest is enormous.
The price for this excursion is 16 €. Many people, even the Romans, do not know that „Papa Express“ (which is behind the Basilica of St. Peter and near the house where the Pope lives) is the smallest national railroad in the world.
3. According to some estimates, China has 20,000 kilometers of railroads running super-trains (average speeds over 200 km / h), which is more than any other country in the world together. The plan is to build at least 10,000 kilometers of fast track lines. In the near future, the Chinese railway company plans to increase speeds to some of them and up to 400km / h.
The Fuxing, (in a free translation means “rejuvenated”), will travel over 1300 kilometers long between Beijing and Shanghai for nearly an hour faster than boredom.

As the current fastest train on that line passes for 4 hours and 48 minutes, it can be assumed that the total travel time will be shorter than four hours, ie faster than 325 km / h on average. Specifically, the Beijing-Shanghai express rail line was built at a striking rate between 2008, when the works started and in 2011 when the trains began to drive regularly. The trains are equipped with a new system that will automatically slow down in emergency situations and stop the train to prevent traffic accidents.
4. The fastest train in the world is the Japanese maglev L0 series, which achieved a speed of 603 km / h in 2015 on testing. These trains are expected to drive through the new Chuo Shinkansen line between Tokyo and Osaka. Its first part, from Tokyo to Nagoya, should be open in 2027, and trains should run at speeds up to 505 km / h. Due to high speeds, super-fast train tracks have no crossings and are protected by a wire fence.

5. Although speed primates have trains produced in Japan and China, those produced in Europe are also among the fastest in the world. And as time passes, they become increasingly popular among the tourists and the domicile population of that state. The cars carry a greater number of passengers at a time than they are in one plane. The loading and unloading procedure is faster. Sometimes, the advantage of traveling by train, is the possibility of panoramic sightseeing and the landscape through which the train travels.
