ABSTRACT:
A steering arm assembly for a railway truck has an undercut compound radius between the body portion and the longitudinal segment on of each side arm in order to decrease the stress intensity at this location, which resultantly provides increased flexural strength to the assembly while maintaining the clearance between the steering arm and truck components.
