The image shows a group of firefighters in a tunnel. The tunnel appears to be underground, as there are concrete walls on either side of the tracks. The firefighters are wearing helmets and protective gear, and one of them is holding a hose. In the center of the image, there is a red fire truck with the word "Feuerwehr" written on the side. The truck is spraying water onto the ground, creating a cloud of smoke. There are also several yellow hoses and other equipment scattered around the tunnel.
