The saving of energy at the car end of the line does not by any means represent the major portion of the saving effected. In consequence of the fact that the motor is maintained at constant speed under constant load, it is quite evident that the variations of load usually so exceedingly noticeable at the power station will be done away with. It will be, therefore, possible to build and equip the power house of such a line of r,mch units that it may be constantly working at its maximum
