The following article describes the controls on electric, rather than steam trams.The operation of trams is relatively simple. As trams run on rails, they do not require steering controls. However they do require controls for the smooth application of power and for braking and to control forward and reverse running. Different controls were operated by the motorman's (driver's) hands or feet. In more modern vehicles controls are generally located on a driver console panel. Some controls can be used to do a variety of tasks. Trams do not have clutches or variable gears, although they do have fixed gears between their motors and wheels. Thus trams have no need for controls to operate their gears. Most of the important controls on a tram are actually electrical switches.
