The drop openings,four in number, are 2 ft. 4 in. by 22 in., and are located be-tween the intermediate and center floor timbers. a great deal of light upon the hitherto obscure question ofhow trains are affected by the atmosphere. The experiments were made upon small models, constructedto a scale of 1-32 of the size of the ordinary box car, the as-sumption being that relative resistances will be directly pro-portional to the surfaces of the cars, and that conclusionsdrawn from the small models will apply to the full size Goss presents the matter for practical use in theform of equations, in which the factors of the length of thetrain and the area of cross sections are considered, the headresistance and the resistance of the cars being provided for. ^V^\J^VA^ Section Showing Body Bolster. Draft Rigging. The draft timbers are white oak, 5x7% in., extending to thebody bolsters. The draft springs are double, with two coilseach. Gould draft arms are used, each being connected to thedraft rod cross timbers by a one-inch rod passing througha lug on the outer side of the arm. Two % in. rods connectthe draft rod cross timbers. The trucks are of the rigid, diamond frame type, with twotypes of bolsters, American steel and the Simplex. The draw-ing shows the latter. The spring plank is a 12-in. 30-lb. steelchannel. At the bearing between the bolster spring plates andthe truck bolster a pocket is formed in the end of the bolster.
