Abstract
The present invention includes a track () of a track system with straight, transition, curved, and switch track sections. The invention further comprises bogies () for vehicle cabins suspended under the track. Track sections of the track have an upper rail () and one or two lower rails (). Further, a bogie () has fore and aft sets of upper guide and switch wheels (), and one set of lower guide and switch wheels (). The bogies () also have one left and/or one right load bearing wheel () and one drive wheel facing upwards and engaging a downwards directed drive wheel running surface () of the upper rail. Each set of lower guide wheels consist of left and right wheel pairs () so that transition sections can be passed without moving any parts of the bogie (). Switch wheels () are separated from guide wheels so that they can be positioned according to the preferred direction of travel well before reaching a switch.
