CCTV news: When traveling on the high-speed rail, some careful passengers will find that the seats on the high-speed rail include A, B, C, D, and F, and they skip seat E directly. Many friends were puzzled, and some netizens joked that "E went to test everyone's eyesight." Why is there no E-seat on the high-speed rail? It may be helpful for you to master some high-speed rail knowledge. Let’s take a look at today’s “Spring Festival Travel Increases Knowledge: How Much Do You Know About High-Speed ​​Rail”.

On high-speed rail trains, business seats adopt the " 2+1” seating arrangement, that is, 2 seats on one side and one seat on the other side. They are represented by A, C, and F respectively. The first-class seats adopt a "2+2" seat arrangement, that is, there are two seats on each side, represented by A, C, D, and F respectively. The second-class seats adopt a "3+" seat arrangement. In the 2" seat arrangement, the three-seat side is represented by A, B, and C, and the two-seat side is represented by D and F. However, these seat arrangements do not have the seat E, so where did seat E go?

Wang Fang, conductor of the Taiyuan Passenger Section of the National Railway Taiyuan Bureau, said that the reason why high-speed rail trains do not have E seats has to do with the aircraft cabin. Early single-aisle aircraft generally had 6 seats in each row, namely A, B, C, D, E, and F. "A, F" represents the window position, "B, E" represents the middle position, and "C" ,D" indicates the position near the aisle. Over time, the international convention of using specific letters to represent window, aisle, and middle seats was formed. High-speed rail continues this international practice. However, the maximum number of seats in a row of high-speed trains is 5, so in addition to retaining specific letters for windows or corridors, the numbers are reduced starting from the larger letters, so there are no "E" seats on high-speed trains.

Wang Fang also said that by logging into the 12306 website or mobile app, you can select the travel date and train number. After submitting the order, you can enter the seat selection interface if there are sufficient remaining tickets. If you want a window seat, choose seats "A and F", and if you want to be next to the aisle, choose seats "C, D". If you can sit anywhere, just click "OK" without selecting a seat, and the system will automatically assign a seat to you.
