The cinematography would favor close-ups—the little details that make a train feel alive: the thumb-scraped tickets, the slow swing of a kettle over a single-burner stove, the way monsoon light turned the carriage windows into watercolor panes. Sound would be its companion: the rhythmic clack of joints, vendors calling mangoes and samosas at platform edges, a radio playing old filmi songs that people lipsync in passing. There’d be a scene in the dark when two strangers share a thermos of tea and trade stories until the whistle blows them back into anonymity.
