The image shows a group of firefighters walking through a tunnel. The tunnel appears to be underground and is made of concrete. The firefighters are wearing full protective gear, including helmets, jackets, and gloves. They are walking on a railway track that runs through the tunnel. On the right side of the image, there is a stretcher with a yellow stretcher attached to it. The stretcher is being loaded onto the stretcher, and there are several other stretchers on the track. The walls of the tunnel are covered in concrete, and the ceiling is high and arched. The image appears to have been taken at night, as the tunnel is dimly lit.
