The Monorail-system is a special type of 9V powered transport shuttle running on special rails with just one lane.
The train is propelled by a special motor module with gear drive in the center section between two end cars - while one car transports the 9V battery box. It was controlled by a dial switch on a special rail of each station - with possibility to start/stop or change direction.
The special about the rails - beside the gear tracked lane - was the driving on different height levels.
