The image shows a close-up of a train engine. The engine is mounted on a green metal frame with a chain attached to it. The chain is secured to the frame with screws and bolts. There are two large wheels on either side of the engine, one on top of the other. The wheels appear to be made of metal and are black in color. There is a small yellow valve in the center of the valve, which is likely used to control the engine's movement. The background is blurred, but it appears to be an outdoor setting with trees and foliage visible.
