About Our Logo
The CERA logo, designed by CERA member Thomas A. Carpenter, depicts the handle of an electric interurban multiple unit car controller incorporating a "dead-man" button. So what is that? This essay explains how the controller handle is the symbol of the train motorman's profession.
The controller of an electric railway vehicle is the equivalent of the gas pedal of an auto. Each of them is the instrument by which the person operating the vehicle calls for power to maintain speed or accelerate. Traditional electric railway car controllers were the state of the technological art from the 1890s to the 1930s.
The controller was operated by the motorman with his left hand. He set the crank-shaped controller handle in any of several positions or points. One position, calling for no power, caused the car to coast. Each of the other points applied power to the traction motors that propelled the car.
