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 . 17. • The American can work economically in a cuthaving a 2 ft. or even lighter face, because of its full-circle action and its ability to work at all times with-out use of out-riggers of any kind. Working Against a Heavy Face The American here again demonstrates itsflexibility of performance and superiority over thesteam shovel on account of the full-circle swing,which enables it to take the material from the faceof cut and deposit in cars or wagons directly in therear. The steam shovel cannot do this because itsboom only swings half a circle. 13 Building a Railroad The American will dump higher and at agreater distance from the track than the ordinarysteam shovel. The steam shovel cannot load into cars up on thebank alongside, and make greater than a 5 ft. cut. With the American on center grade line, themaximum cut that can be made, loading materialinto dump wagons or cars 7 ft. above surface rail,up on the bank, is: Depth of cut 11 ft. 6 at bottom, 16 , 1 to iillillll=ll@lllilllSII€llll SCALE AsilFT. American Ditcher Digging Cut 11 -(J Deep, and LoadingInto Dump Car or Wagon on Bank, In 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
