From a high vantage point above Berlin’s Alexanderplatz, the city’s pulse reveals itself in a streak of yellow and red. The S-Bahn slices past the iconic Alexa mall, its golden roof catching the midday sun. Below, the streets hum with buses, pedestrians, and the quiet geometry of urban life — all connected by this shimmering line of motion. The tracks are the arteries; the train, the pulse.
