The column headed Wheel No. indicates theorder in which the wheels passed over the : I indicates the front wheel of the forwardtruck; 2, the second wheel; 3, the front wheel of therear truck, and 4 the rear wheel. The blank spacesin the column of lateral thrust indicate no recordobtained, because of the fact that the initial pressureput on the apparatus was greater than the wheel 3S thrust, so that the thrust produced no movement ofthe pen. Throughout the whole series of tests theweather was fine and the rail dry. For convenience of reference and comparison thelateral thrusts of the front wheel of the forwardtruck have been plotted on the accompanying dia-gram. This diagram shows graphically the widevariations in the lateral thrust of the wheel. Fromit it is impossibl
