The quill drive and details are the same as on thepresent locomotives and this type of flexible drive hasproved very successful. It is the twin motor type arid isfitted with a single gear meshing with two pinions, oneon each amiature shaft. The frame of the motor includestwo integral bearings carrying a hollow shaft or quill,which surrounds the driving axle. Sufficient clearanceexists between the axle and the quill to ])ermit the axleto accommodate itself freely to track irregularities. Atthe end of the quill, a gear is mounted, meshing with themotor pinions. At each end of the quill are bolted sixcastings, each gripping one end of a helical spring hxratedbetween the wheel s]X)kes. The other end of each springis grip])ed in a which is l
