Abstract
A railway locomotive structure has a stabilized self steering bolsterless and pedestalless powered railway truck with a pivotable carbody beam connecting the truck frame with the carbody for low axle weight transfer and supplemental stabilizers in the form of rubber cushions connected with axle steering beams to aid stability in the steering action, particularly during straight ahead running. Hydraulic or friction damping of the suspensions and steering mechanism are also disclosed.
