The Japanese railway system is regarded as one of the best in the world. If you ever find yourself riding a train in Tokyo, you'll notice that the conductors have a peculiar habit. As each operator runs the train, they proceed through a ritual of pointing at different objects and calling out commands. When the train approaches a signal, the operator will point at it and say, "Signal is green." As the train pulls into and out of each station, the operator will point at the speedometer and call out the exact speed. When it's time to leave, the operator will point at the timetable and state the time. Out on the platform, other employees are performing similar actions. Before each train departs, staff members will point along the edge of the platform and declare, "All clear!" Every detail is identified, pointed at, and named aloud.fn1 This process, known as Pointing-and-Calling, is a safety system designed to reduce mistakes.
