The image shows the interior of a train car with a narrow corridor. The walls are made of metal and there are pipes and wires running along the sides of the corridor. On the left side of the image, there is a large metal pipe with a decorative design on it. Next to the pipe, there are several pipes and valves. In the center of the hallway, there appears to be a control panel with various buttons and switches. A red fire extinguisher is hanging on the wall next to the control panel. The hallway is dimly lit and has a small window on the right side, allowing natural light to enter. A person can be seen walking down the hallway.
