This is as wasanticipated, because ammeter readings taken on the carsshowed that there was but little difference in the currentconsumption of the motors with and without trailers. Somany items come in between the coal pile and the motorthat it is hard to determine exactly what causes the vari-ations. The month of July, during which the recordwas taken, was uni
