The invention is a guidance device for a railway vehicle and, more generally, is a guidance device for any track-following vehicle. The guidance device has a guide wheel which is complementary with a substantially circular guide rail, and which is capable of pivoting about the guide rail from rotation about a substantially horizontal axis to rotation about a non-horizontal axis. The guide wheel is pivoted by a pivoting member to which the guide wheel is mounted. The substantially circular guide rail extends parallel to the main rails of the track and is located at least in the area of a bend in the track, e.g., a branch in the track, a curve in the track, or the like. The guide rail is preferably positioned laterally outboard of one of the main rails of the track. The track may additionally comprise a second guide rail which is positioned laterally outboard of the other main rail of the track. In an alternate embodiment, the track may have a single guide rail positioned between the main rails of the track. |
