Why is the No. 21-E better than any other single truck? First, because each side frame is made ofa single solid forging instead of a multitude of pieces riveted together. Second, because the spring ar-rangement gives it the easiest and steadiest riding qualities, and it may be run at a much higher speedthan others without oscillation, and third, because it carries the car body two inches lower than any are other points of difference greatly in its favor, such as simplicity of construction, making re-pairs easy and facilitating inspection; also the method of building is peculiar to our shops, but the three. BRILL 21 = E TRUCK (Patented) points of excellence given are the main points, and are absolutely essential to a long and healthy lifeof a single truck under modern conditions. If solid forged side frames are necessary for short-base doubletrucks, they are all the more necessary for a long base single truck, because of the greater tendency to getout of square, and squareness is the prime requisite of all trucks, the alignment of the motor bearingsand all parts depending upon it. Riveted and built-up frames have little lateral strength—that kind of con-struction is only suitable for bridges and buildings which bear a vertical static load. Compare the springsystem of the 21-E truck with others and see how the long steady spring base is obtained that bringsthe load most directly to the boxes and reduces the height from rail to car bodv to the minimum.
