Abstract
A monorail switching arrangement is disclosed for switching the travel of a vehicle to either a continued-travel monorail section or a change-of-direction switched-travel monorail section, characterized by the provision of a plurality of vertically displaceable horizontal switching wheels arranged on opposite sides of the first monorail section for displacement between upper and lower positions in alternate engagement with pairs of continued-travel and switched-travel control tracks mounted on opposite sides of the monorail, respectively. In one embodiment, the switching wheels are vertically displaceable relative to the chassis, and in a second embodiment, the chassis and the switching wheels are vertically displaceable as a unit relative to the vehicle support wheels and the monorail.
