The image shows a window of a train with the words "OPEN ONLY FOR EMERGENCY VENTILATION" written on it. The window is open and the view outside is of a cityscape with buildings and trees. The train appears to be a passenger train with a red and white stripe on the side. The image is taken from inside the train, looking out the window at the city below. There are a few people visible through the window, and one person's hand can be seen on the right side of the image.
