Locate the frog with a view tocutting the least possible number of rails. After youhave determined where the frog point will come, markthe place on the track rail, take from the turnout tablethe distance from the switch point to point of frogcorresponding to the number of the frog which isused. The head block can now be located by meas-uring the total distance obtained from the frog point. Make marks with chalk along the flanges of the railbetween the head block and frog, so that the switchties can all be placed the proper distances apart fromcenter to center. After the switch ties have all beenarranged according to their proper lengths, lay them. Fig. 53. Method of Spurring Out Cars out alongside the track, and see that each tie is num-bered, and in its proper place as it will lie in the take out the old ties and pull in each new tiein regular order. When pulling the ends of the ties to line, time canbe saved by using a gauge, made by nailing a cleatacross a piece of board, allowing eighteen or twentyinches to project beyond the cleat. Have this gagesquare at each end, lay it with the cleat against theend of each tie and draw a chalk line across the tieat the end of the board, marking all the ties the samelength from the end. This chalk line should be placedso as to mark the position of the outside flange of therail or where the spikes are to be driven on the line FROGS AND SWITCHES 261 side. When the ties are all in place under the track,the ends of all the ties will line uniformly on the lineside but how closely they will line up on
