This particular portion of track was part pull the rails entirely free from the ties and thoroughlybreak the concrete within the railway strip. This oper-ation, including the moving of the machine, requiresfrom four to six minutes. The machine is moved along the track with an elec-trically operated Brown-Hoist crane, the operation con-sisting of raising the puller a few inches above thepavement and moving it entirely suspended to the nextposition. We have found it desirable to follow immediately be-hind the machine with two 15-ton hand jacks, as thisfacilitates the removal of concrete and paving FIG. 1—PULLER IN POSITION READY TO PULL TRACK. FIG. 2—CONDITION OF TRACKS AND PAVING AFTERPULLING THE TRACK. FIG. 3—HAND JACKS USED TO REMOVE BROKEN CONCRETE of a line recently abandoned by the company, andunder the abandonment proceedings was required to beremoved within a time limit. To remove these tracks the company designed andconstructed a machine which consists of two 200-tonhydraulic jacks, mounted on horizontal beams which As yet we have prepared no comparative estimatesof cost, but we find that we are able to pull out about120 lineal feet of track per hour. We have estimatedthat with this machine and six men, we can removemore track than we could with 200 men under the ordi-nary method of sledging and gadding.
