　Released in December 2021, its design has become a hot topic of the Osaka subway new vehicle 400 series. Osaka Metro released a video of its details on Thursday, January 6, 2022. [also very good in the car] look at the details of the 400 series with pictures 400 series is a new central line vehicle responsible for visiting the 2025 Kansai World Expo in Osaka. It makes people realize that the future design of the spaceship, one for each group, is not a long seat, but a cross-seat car for one person, which is a big point. In addition, a variety of new axles are introduced in the animation. Among the front vehicles, the first counter was set up as a "practical space" on the Osaka subway. USB sockets are set up here, which can be used as workspaces and community spaces. I heard that the Wi-Fi in the car is also very complete. In terms of safety, when the door is closed and the luggage and fingers are stuck, it is detected and can be easily pulled out by temporarily weakening the opening and closing force of the door. Another major feature is the improvement of the function of air conditioning. In the past, the air conditioner took into account the temperature and congestion in the car and carried out real-time control, but there was a time lag before the air conditioner came into effect. In the 400 series, the temperature outside the car, the time period and the congestion at each station are collected during daily driving. In order to maintain a comfortable interior environment, a "forecast" is developed to control the air conditioning. For example, step up the air conditioning before arriving at a station where you know a lot of people will get on the bus. In addition, it is also equipped with air purification devices to suppress odors and allelic materials. The 400 series is scheduled to debut in April 2023. According to Osaka Metro, only a small number of functions are introduced in this video.
