The image shows a group of men working on a steam locomotive. The locomotive is blue and green in color and has the word "Nelson" written on the side. There are three men standing on the locomotive, one of them is on a ladder and the other two are working on the engine. The man on the ladder is wearing a white shirt and blue jeans and is holding a tool in his hand. The other two men are kneeling on the ground next to the ladder and appear to be working on it. There is a red fire extinguisher on the right side of the image and a building in the background. The ground is covered in gravel and there are a few other items scattered around.
