Inside a passenger train carriage, a woman in a dark vest over a white shirt, with a blue bow in her hair, is cleaning the seats. She is placing disposable white headrest covers with blue and red writing on each seat. The seats are blue with a textured pattern. A man wearing a black jacket walks by behind the seats. The train window is visible, with the view outside obscured. The interior is lit by overhead fluorescent lighting. Labels such as "5D" and "6F" are visible above the windows.
