Art style: Vibrant 3D animation, soft clay-like textures, bright sunny lighting, expressive large eyes, 4K resolution..
A lush, rolling green valley with a shimmering, iridescent train track winding through it. A wooden toy train with rainbow-colored wheels is chugging along the path. Soft, dreamlike lighting with white heart-shaped steam clouds. Wide shot, side-view profile. A palette of every color in the rainbow against a deep green landscape.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Vibrant 3D animation, soft clay-like textures, bright sunny lighting, expressive large eyes, 4K resolution." style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Vibrant 3D animation, soft clay-like textures, bright sunny lighting, expressive large eyes, 4K resolution.". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Vibrant 3D animation, soft clay-like textures, bright sunny lighting, expressive large eyes, 4K resolution." idiom, not in any other medium.
