Here's a description of the video: The video shows people waiting for and entering a train at a subway station. A person in a green tracksuit, black cap, and with a black backpack is standing on the platform, looking at their phone. As the train doors open, people begin to enter the train. The individual in the tracksuit is among those who board. Once inside, the train car appears mostly empty, with blue seating and silver poles for support. The person in the tracksuit walks further into the car. The environment is a well-lit subway station with modern architectural details.
