Viewed from behind, several passengers are sitting or standing in the cabin of a sleek, high-speed train departing from Beijing. In each row and on each side of the aisle, there are two large seats with gray seat-backs and overhead shelves for storing luggage. The front of the cabin has two digital display screens set into dark wood paneling; the next cabin is visible ahead, through the open door.
