Description

This prompt is useful for creating educational diagrams of machinery, vintage children's book illustrations, and printable coloring pages. The combination of 'black ink on a white surface' with 'clean outlines' ensures that the locomotive remains graphic and easily reproducible, preventing any muddy tonal transitions that would obscure the mechanical details necessary for diagrammatic clarity.

Suggestions

Change 'cartoon illustration style' to 'woodcut engraving style' for an older feel.
Add 'cross-section view' to show internal mechanisms.
Replace 'stylized clouds' with 'simple geometric shapes' for a more technical look.
