A vintage 1950s travel poster style illustration depicting a grand central train station hub viewed from above, with multiple colorful railway lines converging from different directions into one elegant art deco terminal building. Each incoming track carries a small stylized steam train in different jewel tones (ruby red, emerald green, sapphire blue, amber gold) representing different approval workflows merging into one unified destination. The station features ornate brass fixtures and warm sepia undertones, with dramatic sunbeams streaming through a massive glass ceiling dome. Tiny silhouetted figures stand on platforms, some with raised arms making decisive gestures. The composition emphasizes convergence and order emerging from complexity, rendered in muted pastels with bold geometric shapes characteristic of mid-century commercial art.
