Abstract
The invention relates to a track-guidable omnibus, each of the lockable vehicle wheels of which is preceded by an associated transverse guide roller arranged near the ground, which is mounted in a rigid position relative to the wheel plane of the vehicle wheel by a bracket arm. An easily exchangeable change part, which contains a preferred breaking point, is interposed between the transverse guide roller and the end of the bracket arm in the end region of the bracket arm. This is intended to prevent secondary damage to the steering in the case of ground collisions. In order to prevent 'derailment' from the track in case of a roller breakage during track-guided service of the vehicle, an emergency contact surface, which temporarily and provisionally assumes the function of the transverse guide roller when the latter is broken off, is provided protected between the transverse guide roller and the vehicle wheel. The emergency contact surface may be formed by a small skid or by a small emergency roller.
