How Northern Pacific is using special equipment pulled along behind work train to skeletonize and make initial lift or new ballast without jacks; as plow or sled moves along, track is "humped up" over it, bottoms of ties sliding across runners on top of device; with plow, crib material is carried to shoulder; sled redeposits ballast in layer under ties.
