The image shows a black locomotive with the number 3166 on the front and the word "SOUTHERN" written in yellow on the side. The locomotive is parked on a railway track with several other railway tracks in the background. On the right side of the image, there is a freight train with several cars and a trailer attached to it. The train appears to be a diesel locomotive, as there are no other locomotives visible in the image. The sky is overcast and the ground is covered in gravel.
