1. Platform security door: In order to prevent passengers from accidentally falling into the subway track while waiting for the subway, many subway platforms are equipped with security doors, which can effectively protect the safety of passengers.
2. Digital guidance system: In many subway stations, digital guidance systems will be set up. By displaying the subway route map and station information, it is convenient for passengers to know where they are and the direction they need to go.
3. Car air conditioning: In order to provide passengers with a comfortable ride experience of hot summer and cold winter, many subway cars are equipped with air conditioning systems to effectively control the temperature inside the car.
In addition to the above points, I think the subway can also add some convenience facilities, as follows:
1. charging station: With the change of people's life and work style, more and more people need to charge in the subway, so adding charging stations can provide more convenient services for passengers.
2. Free Wi-Fi: In modern society, both life and work need the support of the network. Adding free Wi-Fi services can provide more convenience for passengers.
3. Seat heating: In the cold winter, the seats in the subway can provide passengers with good rest and warm conditions. It will be more comfortable if the seat can still be heated.
4. Self-service facilities: such as vending machines and ATMs can provide passengers with more convenient shopping and withdrawal services.
To sum up, the thoughtful design and convenient facilities of the subway continuously enhance our travel experience. I believe that in the future, with the development of science and technology and the increasing demand for travel services, the subway will provide more convenient facilities and make travel more intelligent and efficient.
