The image shows a close-up of the side of a train engine with the number 4 on it. The engine is black and appears to be old and weathered. The train is parked inside a tunnel-like structure with a green wall on the right side. There is a person wearing an orange hard hat and safety vest standing next to the engine, possibly inspecting it. In the background, there are trees and a blue sky. The image is taken from a low angle, looking up at the engine.
