Abstract
In a railway car truck a transverse member is provided including spaced sides and a member joining said sides to define a hollow portion having an open bottom such that the shear center is spaced upwardly from the neutral axis of the section. A truck center bearing is provided at about the mid portion of said transverse member which is located at about said shear center so that torsional deflection or twisting of the transverse member is avoided.
