The image shows a long, narrow walkway with a high ceiling made of metal mesh panels. The walkway is made of concrete and has a concrete floor. On either side of the walkway, there are large windows that offer a view of the city below. The windows are covered with black mesh panels, allowing natural light to enter the space. In the background, there is a train track and a train station. The sky is overcast and the overall mood of the image is gloomy.
