The image shows a Union Pacific locomotive, numbered 511, on a railway track. The locomotive is yellow and black in color with the words "Union Pacific" written in red on the side. It is a diesel locomotive with the number 511 on the front and the Union Pacific logo on the sides. The train is moving along the track, with another locomotive visible on the right side of the image. The sky is overcast and the ground is covered in grass and gravel. The image appears to be taken from a distance, as there is a wooden fence visible in the foreground.
