ABSTRACT:
A six-wheel railway motor truck for swivelly supporting a locomotive body is connected to the same for the effective transmission thereto of draft and braking forces at a level at or near that of the rail whereby the vertical moment arm through which traction forces might act to tip the truck frame and thereby cause load transference from axle to axle is minimized, with corresponding minimization of such load transference. The truck comprises a rigid frame resiliently supported on the three axles, a body support bolster supported on the frame fore and aft of the middle axle for swivel about a point on the longitudinal center line of the truck, the central portion of the bolster above the middle axle being open to provide unobstructed access to the middle axle motor and to provide vertical clearance therefor while maintaining the bolster and overall truck height relatively low. For transmitting longitudinal forces from the truck to the supported body substantially at rail level, the bolster is connected to the vertical body at each side by a pair of longitudinally upwardly and outwardly inclined links arranged so that their axial projections intersect at track level.
