We came to the gate of the subway station, which was already crowded with people. We walked down the stairs to the ticket office, pressed the name of the station on the screen of the automatic ticket vending machine, and then threw the change coin into the ticket vending machine. Only with a bang, a piece of plastic paper fell from the machine, like a one-dollar three-green coin. This is our subway ticket.
We took the ticket and swiped the card on the automatic card reader and entered the scene. After waiting for about five minutes, the voice of "whoops-"sounded in my ear, and the city bureau finally came! Only to see two long "dragons" with golden light shining on the track coming from a distance. There are many automatic doors and huge transparent windows on both sides of it. We walked into the orderly trains of the subway and found them clean, bright and spacious. We found a place to sit down. I continued to look for it, only to see that every car inside was connected, and the head and tail could be connected. In the middle of a row of upright carriage handrails, it is as powerful as a sentry. The subway began to run and moved forward quickly. I looked out of the window and saw a dark scene that I couldn't see outside. People sat firmly in the car, without traffic jams and red lights, and arrived at their destination in a blink of an eye.
With the subway, I get in and out more conveniently and quickly.
