A wear plate for use with a railway truck, the wear plate being configured for installation on a downwardly facing surface of a pedestal opening of a side frame of a railway truck. The wear plate includes a base and a pair of side walls extending upwardly from opposite sides of the base with inwardly disposed locking features designed to engage the pedestal when the wear plate is installed, the locking features in a preferred embodiment being configured as resilient projections that engage, clamp or drag lock onto opposite sides of the pedestal with the base of the wear plate protecting the downwardly facing pedestal surface. The wear plate may be constructed from malleable or ductile metals or plastics.

A chassis (100), in particular a low-floor chassis, for a rail vehicle, in particular for a tram-way. The chassis (100) comprises at least four wheels (4) each having a wheel bearing, at least two wheel axles for suspending the wheels (4), a chassis frame (1) and a primary suspension for suspending the wheels (4) relative to the chassis frame (1). The primary suspension has at least four torsion bars (20). Two torsion bars (20) each, in particular two torsion bars on one side of the chassis, are connected via a connecting element (21) in such a way that the torque of the torsion bars (20) oppose each other, in particular the torques essentially cancel each other out.
