The image shows a group of firefighters walking through a tunnel. They are all wearing full protective gear, including helmets, jackets, and gloves. The tunnel appears to be underground, as there are concrete walls on either side of the tracks. On the right side, there is a metal platform with several yellow fire extinguishers on it. The firefighters are walking towards the platform, and one of them is holding a hose. The image appears to have been taken at night, as the tunnel is dimly lit.
