Abstract

A friction damping arrangement for a railway vehicle comprises first and second relatively moveable vehicle components (14,16), a friction wedge (18) having a surface (37) arranged to co-operate with a surface of the second vehicle component (16), and resiliently urged towards the first vehicle component (14), and a resiliently deformable component (48), located between the first vehicle component (14) and the friction wedge (18), the resiliently deformable component (48) being deformable to allow relative movement between the first vehicle component (14) and the friction wedge (18).
