The truck side frames are of wrought iron, 1% in, x 3 section, while the end frames consist of 3 in. x 3 in. side frames are bent downward at the outer ends in orderto clear the car body. Plate gussets brace the frame at thecorners, while the side frames are secured to the transoms by. Type Truck for Detroit United Railway cast-steel gussets of most substantial construction. The trans-soms consist of 9-in. channels. The bolster and center-pin areof cast steel, and the pedestals are forged iron. In accordancewith the practice of the builders, the equalizing beams arepunched from steel boiler plate. The equalizing beam springs are double coil, while thebolster springs are double elliptic. The lower spring plank iscomposed of a pair of 2j/^-in. x 2^ in. angles, suspended onswing links. The top swing link bearings consist of steel cast-ings, which span the channel transoms, and constitute a sub-stantial brace at a point where stiffness is essential. The brakes are inside hung, and the transverse brake beam is pinned directly to the live levers. The brake levers andbrake shoe hangers are carried by the transom gussets.
