Why are the seats on the train facing each other?

Improve space utilization and increase passenger capacity.

Face-to-face chair means that two people use a backrest, which saves more space and design cost than one person uses a backrest.

One of the reasons for this design is to accommodate more seats. Give a chestnut: compare the 25G air-conditioned car commonly used in general speed with the Harmony number CRH380A:

The hard seat of 25G air-conditioned car has 33 more seats than the second-class seat of CRH380A. There are 90 people in the second class of Fuxing CRH400AF, 5 seats more than Harmony.

Face-to-face seats can save the interior space of the carriage, improve the space utilization rate and carry more passengers, thus increasing the passenger capacity.

The train can't turn around

When the train turns back after arriving at the terminal, it can't turn around, but hang the front of the train at the tail to continue driving.

If the trains are seated in the right places, someone will sit with his back to the direction of the train. Maybe you can make up the picture of the whole car sitting with its back to the front.

At present, most of Puller's hard seats have no steering design, and only face-to-face seat design can ensure that people are always in front.

Then the train can run in both directions, with one side in front when it leaves and the other side in front when it comes back.

Although the bullet train runs in one direction, the seats of the bullet train can rotate. After arriving at the terminal, the flight attendant will turn all the seats around and face the direction of the train.
