A person is reflected in the window of a train door belonging to Korea Railroad (Korail) in Seoul, South Korea. The individual, dressed in a light grey zip-up jacket, dark trousers, and white wired earbuds, is holding a black smartphone in their right hand, appearing to take a selfie. An orange tote bag, partially legible with inverted text "LUCKY BAG," hangs from their left arm. The train door is silver-toned with a repeating pattern of light grey, interconnected, bean-shaped motifs. To the left of the window, a red circular warning sign displays a white hand symbol, Korean text "손조심," and English "CAUTION." Below the window, "KOREA RAILROAD" is embossed or printed. Reflected in the window behind the person are the interior details of another train car or a platform, including a second patterned train door and a faint subway line map above it. To the right of the door, a white panel contains emergency equipment, including a red button or handle and operational instructions in Korean and pictorial form. A vertical silver grab handle is mounted on this panel.
