It was found during thetests that this arrangement took the load from the axle and diminished theshocks considerably. In the former runs with car S the vibrations of the sides of the car bodywere so great that it was impossible to accurately read the measuring instru-ments fastened to them. This difficulty was overcome by replacing the two BERLIN-ZOSSEN ELECTRIC RAILWAY TESTS. 17 light wooden partitions near the doors with two portals built of standard ironsections. In order to study the effect of the form of the front of the car on the airresistance, both cars were equipped on the front end with noses, as shown inFigures 10 and 11, which reach down from the roof of the car to within 30 and40 cm. ( and inches) respectively of the head of the rail and which c
