Whenthis occurs an automaticdevice opens the circuitand the dynamo no longersupplies current to theline. If the trolley wirebreaks and falls on thetrack a similar short circuit occurs. If it should not happen to make aground, no interruption takes place until a carreaches the break, and then it must evidently stop. ation of the system can follow. If a trolley wirebreaks the car stops when it reaches the a telephone wire falls across one wire, and theconductors of the railroad are well
