In spotting locomotives about the roundhouse 220-volt current is used with the earlier locomotives, thecircuit being plugged in on the ground side of the con-troller to two motors. The machine is then operatedfrom a stationary controller. On the new locomotivesprovision is made for putting the spotting current onall of the motors through the regular controller bymeans of a single-pole double-throw switch provided forthe purpose. Realizing the importance of extreme care in the han-dling of the high-voltage equipment on the electric loco-motives, the railroad has issued strict instructions.
