In Railway Sleepers, a minutely observed film shot entirely on-board a Thai train, we see kids on school trips, young men travelling north and south, hawkers selling food and horoscope books, families and lovers, vacationers who turn the sleeping car into a party venue. They’re passengers, and they’re also humans. They are, as director Sompot Chidgasornpongse says, a collection of faces that make up a portrait of Thailand.
