Because its steering feature eliminates several major sources of bogie stress and shock, the EMD radial bogie dispenses with more than a half dozen components. The radial bogie has no bolster, no chafing plates, no pedestal liners, no traction motor nose pack and no center-bowl liner to inspect, maintain or replace. Downtime is minimized and bogie maintenance is reduced due to the elimination of weld buildup and machining of bogie pedestals.
