The first thing about a suburban or double-truck caris to lay out the bottom and to locate the intermediateor center sills, so as to avoid having the wheels cut, eitherthem or the end sills, while the car is turning a curve. The radius of the shortest curve the car has to run on isgenerally found by information from the railway com-panj, and the wheel-base of the trucks is, as a rule, is conceded that the longer the truck base or distancebetween centers of trucks the better it is. The problem then is : first, to find the longest truckcenters that will not make the wheels interfere with theend sills; second, that will permit the intermediate sills tobe put far enough apart to give the underneath mech-. anism ample room while the car rounds a curve. If theposition of the truck on the curve is found, the problemmight be considered solved, and to find this position thecurve or center between tracks must be laid down cor-rectly relative to the car. The shortest and easiest wayto do this is to lay off both the longitudinal center line c cand transverse i i (see Figure 2), then draw end sills andside sills and assume the longest centers possible (whichin this case are identical with the king bolts k), and thenby solving the formulas given below, two points, x and yof the curve or center of track are found, when a sweep
