ABSTRACT OF THE DISCLOSURE A railroad-vehicle truck (bogie) with a frame that yields under torsion consists of gantry supports (2) and sole bars (1) welded into an H. The gantry supports (2) are positioned such that the planes of the gantry-support webs (2a, 2c, 2f, & 2h) intersect at one or more lines (S1-S6), which lie within an imag- inary cylinder with a diameter a that is 75% or less of the height h of the highest gantry support. This truck frame, which yields under torque while having sufficient corner rigidity, will prevent the high material stresses that result from torque on the truck. The truck will, especially when employed on a freight car, be particularly simple and stable-running.
