The image is a black and white photograph of a group of men working on a large machine. The machine appears to be a steam locomotive or a similar type of locomotive. There are several men standing on top of the machine, some of them are holding a large piece of equipment, while others are walking around it. The men are wearing hats and appear to be in the process of loading or unloading the equipment. In the background, there is a building and a fence, suggesting that the photo was taken in a construction site. The image appears to have been taken in the early 20th century.
