The car wheels and axle are driven from thecenter of the axle by a worm and worm wheel,an opening being left in the revolving journal ofthe worm wheel and a segment of the worm wheelbeing removable to admit the axle. In order thatthe wheels may be held as rigidly as possible, thecar wheel revolves on its own journals. Anotheradvantage of this arrangement is that in grindingwheels with fiat spots, in many instances thecenter holes in the axles may have been injured,or the journals may have been worn eccentricwith the center holes. The journals rest on ahalf-bearing at either end, this
