ABSTRACT:
A bolster14for a bogie of an articulated railway wagon is shown including supports for constant contact sidebearers in the form of two pairs of brackets such as26A and26B being integral with the bolster14at its opposing respective ends. The brackets such as26A are each adapted for fixing of the constant contact sidebearers which in turn are arranged to contact a corresponding wear plate mounted to an articulated connector50. In a preferred example the corresponding wear plates are mounted to corresponding brackets52A,52B which are cast integral with respective male or female articulated connector components54or56. Each bracket26A/B extends laterally from the bolster14and, when viewed in plan, each bracket26A/B has a longitudinal axis of symmetry which is orthogonal to a radius from a central rotational point of the articulated connector50of the railway wagon.
