This is a drawing of a steam locomotive crossing a bridge. The image shows a steam engine with the number 3002 on its front moving across a large steel bridge. The drawing emphasizes the mechanical form of the locomotive and the industrial strength of the bridge's steel trellis. A body of water is visible below the bridge, extending into the distance, with a steamboat navigating the waters under the bridge. Puffy clouds of steam or smoke rise from the locomotive, enhancing the sense of movement and energy in the drawing.
