"The elevated subway station hums with activity. A sleek train, its surface covered in adaptive LED panels displaying route maps and weather updates, glides silently into the station. Passengers of various backgrounds step on board, their holographic wrist devices flashing green as they pass the contactless turnstiles. Inside the train, soft ambient lighting adjusts automatically to passenger density. Seats are equipped with AR displays for entertainment, news, or productivity. Outside the large windows, the city rushes past: industrial zones with towering chimneys in the distance, neighborhoods with glowing rooftop gardens, and streets teeming with activity. The rhythmic announcement of station names, overlaid with weather updates and ads, creates a sense of seamless automation."
