A tram driver checking the situation at the front door, Shanghai, 1936. Tram drivers stood for the whole trip behind the handles for direction and speed (only in the late years they were offered a tall stool), and the bell sound was caused by driver’s foot pressing down on a metal treadle that hit against a metal device and produced clapping sound. https://www.viewofchina.com/trams-in-shanghai/ #china #shanghai #history
