The transoms are 10 which are fastened to the side frames by meansof 14 in. gussets at the top and bottom and a 5 in. by 3j4in. angle at the web. The side frames are steel castingsof channel section at the center and stiffened by ribs, asshow-n on the engraving at the pedestals. The truck Ixtlster is short being only 42 S in. long and7 S in. wide. It is carried by a single semi-elliptic springof 17 leaves, with a length of 56 in. from center to centerof supports. Sefiember, 1923 R.\IL\VAY AND LOCOMOTIVE ENGINEERING The detail of one-half of this spring and its hangershows the construction. The side bearings are only 38in. from center to center. The spring hanger has a dropof 9 in. and a spread of 2^2 in. at each side, so that theangular resistance of the hanger to the swinging of thetnick is more than that usually
