It assumes a plate form between the cylindersand the first driving pedestal where it is narrowed down to 3in. in thickness and is 24 in. deep. This method gives flexibilityat a point where difficulty is experienced with breakage in thesevery large and heavy frames. The trailer frame is in two parts,both being of plate design, the inner one being 2^ in. thick andthe outer \Y2 in. thick. These are spaced 18 in. apart and thetrailing wheel comes between them. The inner one is securely. bolted in a recess in the main frame and the outer one is securedby cast steel filling pieces at its ends. Clip pedestal binders are used, being secured by three 1% at either end. The fastening at the cylinders is by twoif& in- vertical bolts front and back and by nine l/z in. hori-zontal bolts. The frame bracing has been given careful atten-tion and broad cast steel plates are secured between the upperrails at two points in the. main frame, one being over the frontpedestal and the other between the second and third pair ofdrivers. There are also several cross ties, binding the lowerrails together, as well as the heavy crossbar at the front end of the fire-box. Trailer Truck.—The accompanying illus-tration shows the details of the radial typeof trailer truck which has been applied tothis locomotive; it consists of a framehinged at the forward end and secured bya spring centering device in the rear.
