An AC motorized wheel arrangement includes a wheel frame including a flange for attachment to a truck body; a wheel hub; roller bearings for supporting the wheel hub on the wheel frame; a shaft; an AC motor attached to a portion of the wheel frame facing an inboard side of the wheel for turning the shaft; a transmission attached to a portion of the wheel frame facing an outboard side of the wheel and connected to the shaft and the wheel hub for turning the wheel hub; and a service brake mounted between the wheel frame and the wheel hub. In a ventilation arrangement, two wheel frames are attached to opposite outer sides of and axle box and two alternating current motors are positioned in the axle box with each motor frame attached to one of the wheel frames. The motor frames include holes for permitting air from the axle box to enter the motors, and an air outlet housing is positioned between the two motors for receiving air from the two motors and directing air out a rear opening of the axle box.
