[Commentary] The K3 / 4 international train that was caught on fire in the movie "囧 妈" is an international intermodal train (hereinafter referred to as the national train) connecting Beijing, Ulan Bator and Moscow. Duan is responsible for the train crew and runs 7818 kilometers one way. It is the passenger train with the longest mileage in China and is known as the "China's No. 1 Car".

  [Commentary] On May 24th, the K3 / 4 train will celebrate its 60th anniversary. On the 19th, new and old combined transporters came to the Beijing Depot of the Beijing Railway Bureau to witness the moment when the national trains re-hanged the national emblem after the renovation.

  When it comes to the country, it can be described as the four most "most" of the most popular, most "alternative", most interesting and most detailed. Because the equipment is "tall", the high-lying state of the country is the most popular, and it is difficult to get a ticket.

  Our train runs in Russia and Mongolia all the year round, so there is no air conditioning in the hard and soft sleepers. There is air conditioning in the high sleepers all year round. The temperature is the most comfortable and the conditions are the best. There is boiling water in the high-sleeper compartment, the high-sleeper is two rooms, and there is a washroom shared by the two rooms in the middle, which can wash and take a shower.

  [Explanation] The part of the dining car is the most "alternative". As the train standard, the dining car generally follows the whole train, but the national train's dining car can only follow the car to Erenhot, and cannot go abroad.

  Because according to the requirements of quarantine, the dining car does not leave the country, the domestic crew is passengers, vehicles, and public security personnel. The exit of our car is that it runs in Mongolia and Russia. It is the country of operation. Standard, so our dining car does not leave the country.

  [Commentary] The most interesting thing is to replace the "chassis". According to reports, due to the different track systems used by China, Russia and Mongolia, after the train arrives at the Erenhot station, the "chassis" needs to be replaced, and passengers can witness the moment of replacement on the car.

  The biggest feature of our car is that there are two sets of chassis. One is in China. The bogie we see now is called 211A bogie. There is another bogie in Erenhot. When we are going out, Mongolia and Russia must use a chassis that conforms to his gauge when running. That is to say, the bogie is wider. Therefore, we need to change our equipment in Erlian.

  [Commentary] The train menu is the most detailed. Because it is an international intermodal train, foreign passengers are indispensable. In order to solve the problem of passengers ordering, in addition to being equipped with a translation, the train will also translate the menu into multiple languages. On the 60th anniversary, the retired Wang Fushou took out the old-fashioned menu.

  Formulate such a recipe, four countries, Korean, English, Mongolian and Russian, a recipe in four languages ​​for passengers to choose.

  [Commentary] Over the past 60 years, K3 / 4 trains have travelled more than 50 million kilometers and safely transported more than 2 million passengers. Li Yajun, the translator and train conductor of the International Transport Team, said that although the new crown pneumonia epidemic has affected the railway operation, he believes that the epidemic can be overcome and he will always be ready to serve "China's first car".
