The horizontal lines show the speed in miles per hour, while the vertical lines show the time at 5-second intervals. The figures show the time in minutes. Allowing 30 seconds to reduce the speed to 1 5 miles an hour, the run should have occupied about J2 minutes. The diagrams 1 showed very plainly great room for = improvement in both the Eames and the. Westinghouse brake, and were it not for H the low speed would apparently have given the award to the American Brake Company, for up to 9 minutes it will be observed the speed was uniformly maintained between 8 and 10 miles per hour. This record, however, it should be borne in mind, was taken in the autographic car placed in the middle of the train. While the persons riding in this car and the dynamometer car were commenting on the uniformity of the run that was being made, although somewhat below the 15mile speed, an entirely different record was being registered in the rear or 52d car. Here shock after shock was being received, their rapid succession adding to their intensity. Twenty-eight blows of more or less severity were given during the run of 11 y2 minutes, culminating in a shock of 63 in., which broke the train in two. An examination of the train after the stop revealed the fact that 9 of the rear cars had their ends broken and bulged out by the shifting of the loads to such an extent that they were in a dangerous condition, and this, notwithstanding the fact that the wheels with which the cars were loaded had been stowed with special care and the ends of the car blocked with timber.
