ABSTRACT:
A static switching apparatus for a track vehicle includes a main line track and a switch track which at a switching junction both include a conventional track rail and a specially constructed rail. A switching cam including cam faces is positioned at the junction and includes straight and curved cam surfaces which are selectively engaged by cam followers supported on the vehicle to provide for steering of the vehicle. The cam followers are lowered and raised vertically by fluid extensible devices which also move them in an orbital path into cam surface engagement.
