A rail bogie having: an upper frame assembly; and two lower frame assemblies, the two lower frame assemblies being steerable with respect to the upper frame assembly, the upper frame assembly being supported on the lower frame assemblies (28, 30), each lower frame assembly (28, 30) including two side frame weldments and two transverse cross channels; each lower frame assembly (28, 30) supporting a rail wheel assembly having a respective rotatable axle; a gimbaled coupling arrangement (100, 200) is disposed between the two lower frame assemblies and is arranged to connect the two lower frame weldments to one another and to permit rolling, pitching and yawing motion between the two lower frame assemblies; and a steering return arrangement is disposed between the upper frame assembly and each of the two lower frame weldments, the steering return arrangement including vertical steering bars disposed between the upper frame assembly and each of the two lower frame weldments, the vertical steering bars being biased towards a center of the upper frame member and, thus, being configured to center the two lower frame members relative to the upper frame member as the two lower frame members steer along a track, characterized in that the gimbaled coupling arrangement, comprises: a bearing block connected to one of the two lower frame weldments (128, 130); a central connection pin rotatably connected to the bearing block and extending parallel to an axis of rotation of the respective rotatable axle; a bearing pin extending through a mid-portion of the central connection pin and having a longitudinal axis that is substantially parallel to the axis of rotation of the respective rotatable axle; a yoke rotatably connected to the bearing pin and forming a fastener opening extending perpendicular to the longitudinal axis of the bearing pin; a fastener disposed through the fastener opening and connecting the yoke to the other of the two lower frame weldments (128, 130); a resilient washer disposed between the fastener and the yoke, the yoke being in contact with a portion of the other of the two lower frame weldments (128, 130) when the resilient washer is in a first compressive state and at a predetermined distance therefrom when the resilient washer is in a second compressive state. an upper frame assembly;
