Railway trucks including frame sections consisting of a side frame and a transom extending transversely therefrom; spherical bearings connecting the frame sections for relative movement about an axis extending diagonally of the truck; wheel and axle assemblies connected to the side frames by pivoted journal arms; air bellows between the journal arms and side frames for adjusting the height of the side frames relative to the rails on which the truck is riding; a bolster supported from the side frames by bolster spring assemblies; lateral and vertical shock absorbers connected between the bolster and the truck frame sections; and snubbers for limiting longitudinal and lateral movement of the bolster relative to the truck frame sections.
