. Building a railroad; a handbook devoted to a new, speedy and economical method of performing every operation from grading right-of-way to ballasting and maintaining track . n making a heavy cut requiring more than onetrip through on different levels, the steam shovelmust be moved back to commence a new cut, andbe turned around before it starts back, because itonly digs in front; but the American digs back,because it digs and works either way. The steam shovel only digs down to its tracklevel; it has to dig ahead and run ahead. TheAmerican readily digs to 8 ft. 4 in. below levelof track on which it stands, and dumps with equalfacility in all directions in a 60 ft. circle, either comingor going. Suppose you have a cut 10 ft. deep and 16 at bottom to make, with steel laid up to thecut, the material is desired for a fill or ballast, and 14 Building a Railroad you would like to handle it in material cars of goodcapacity propelled by locomotive: Place the American 18 feet to either side ofgrade center, on a level 5 ft. above grade, cuttingdown to level on which machine is working, wasting ma-terial to center for later use, or casting over onto the bank. ^American on One Side of Grade Level Digging Cut 5^5 Deepand Wasting to Center or Casting Over if not wanted. Then lay temporary track throughthe cut just made and complete the cut by runningthe American back through on center line on thegrade level, loading into material cars up on the tem-porary track just laid. When the cut is reduced to 5 ft. above gradelevel, the work train can get over to take materialfor construction, and the American can, if desired,go ahead, returning any time later to reduce the cutto grade level. General Remarks The weight of material from the large capacitydippers on ordinary shovels often seriously damagesmaterial cars. This is not true with the smaller dipper on theAmerican, but the American works so fast thatthe maximum yardage handled compares very favor-ably with shovels of much
