Unlike the ordinary four-pole motorwhere the magnetic circuit is madethrough a separate box casting, the mag-netic circuits in this type of electric loco-motive are competed through the sideand end frames. The pole pieces are castin the end frames and there are alsodouble pole pieces between the armaturecarried by bars which act as part of themagnetic circuit. The pole pieces will be shaped so that. N.

The cab is designed soas to afford a clear view of the whole of the superstructure is to beof sheet steel with angle iron framing,and the doors and windows of the cabare to be fireproof. The driving power of the locomotivewill be furnished by four 600 volt directcurrent gearless .motors, each of 550horse power. This will make the normalrating of the locomotive 2,200 horsepower, with a maximum rating of horse power, or about 50 per cent,greater than that of the largest steampassenger locomotives now in service. The armatures will be mounted di-rectly on the axles and will be centeredbetween the poles by the journal boxes,sliding within finished ways in the sideframes. The armature core will be ofthe iron clad type, the laminations beingassembled on a quill which will be press
