A bogie for use in a railway vehicle having a vehicle body, the bogie having a pair of side frames 12 interconnected by a transverse bolster 14, the side frames 12 supporting therebetween at least one axle and wheel set 24. A mounting arrangement 32 supports part of the vehicle body upon the bolster 14, the mounting arrangement 32 being articulated to allow tilting and other movement of the vehicle body relative to the bolster 14. Secondary springs 30 located between the bolster 14 and the vehicle body resist this movement, and a variable damper 38 damps articulation of the mounting arrangement 32. The degree of damping of the variable damper can be adjusted depending upon whether or not the vehicle is laden. The bogie may also have a brake change over valve which modifies the applied braking loads based upon whether the vehicle is laden or not. There may be a connection between the change over valve and the variable damper such that the damping load applied by the variable damper is dependent upon the brake setting.
