This image displays the interior of a modern Sofia Metro train car. The clean, well-lit carriage features a light gray speckled floor, white walls, and bright turquoise-colored vertical and horizontal grab poles, along with overhead straps. Light blue individual seating is arranged along the sides. A yellow digital display on the upper left indicates "19:07" and "15 March". Ten individuals are visible within the frame. On the left, a man with dark hair and a beard, wearing a blue jacket and dark pants, is seated, looking at a mobile phone in his hands. A brown leather bag rests to his right. In the mid-ground, a male passenger in a dark jacket and jeans stands, also observing a mobile phone. Immediately to his right, a younger male wearing a black puffer jacket and dark pants is crouched or seated on the edge of a seat, focused on a mobile phone. He wears a black backpack with orange accents. Other passengers are visible in the background, seated or standing, many engaged with personal electronic devices. A person in a white fleece jacket and light blue jeans is partially visible on the far right. The scene depicts typical commuter activity within the train.
