Joint Action. — If the joint yields, — and it usually does, —the advancing wheel jumps the depression and dehvers a blow onthe forward rail a little beyond the end. Observation of almostany track will show the effect of this blow on the rail. On singletrack all rails will be hammered at both ends. On double trackeach rail will be hammered on one end. If the rail yields under the load of the passing w
