A red and white metro train is seen approaching and arriving at an underground subway station platform in Barcelona, Spain. The train, with "L8" visible on its front, emerges from a dark tunnel on the right side of the frame and pulls alongside the platform. The platform features gray and white checkered tiles, with two distinct white striped lines running parallel to the tracks. Bright white LED lights illuminate the ceiling above the platform. Inside the train, through its windows, a few passengers are visible. The sound of the train's approach and arrival is audible. On the dark wall of the tunnel, a white rectangular sign with unreadable text is present.
