. Electric railway journal . k for Philadelphia Rapid TransitCompany bar iron, il/2 in. x 4 in. in section and placed vertically tosecure maximum strength. The pedestals are of steel plate, fitted with removable malleable iron gibs. The transomsare 3%-in. x 7-in. channels secured to the side frames bya single gusset plate on each side. This plate is cut out toprovide clearance for the bolster and is flanged to form asuitable bolster stop. The bolster is of cast steel, supportedat each end by a half-elliptic spring suspended by links. The pony axle supports one end of the side framesthrough coiled springs placed over the journal boxes. Onthe motor end the equalizing beams fulcrum directly onthe journal boxes and the motor suspension bar is hungfrom the outer ends of the beams. The weight is trans-ferred to the truck frames through coiled springs, whichare so located that the motor reaction on the frames isalways upward and. the tilting effect on the frames whenthe motor is developing torque is reduced to a minimum..
