Blurred Yellow U-Bahn Train at Potsdamer Platz

Inside a Berlin U-Bahn tunnel, a bright yellow Berlin subway train speeds by, creating a bold motion blur as it becomes a golden streak. In sharp focus near the foreground is the Potsdamer Platz station sign mounted on the tunnel wall, with clear, bold lettering reading 'Potsdamer Platz'. The tiled walls, metallic rails, and cool white tunnel lighting reflect off surfaces, while the train’s warm glow adds contrast. Low camera angle at track level enhances depth and perspective, with a shallow depth of field keeping the sign crisp while the train is a dynamic smear. Cinematic color grading, subtle grain, and a hint of rain-damp ambiance for realism.
