The monorail system was introduced in 1987 and discontinued in 1994. Each monorail train is built on two identical chassis parts with the motor unit in between. The monorail trains run on special 4 stud wide one lane rails. Each rail has vertical teeth running down the middle, the train is propelled by a small gear that runs on these teeth. The trains are controlled by a dial switch on a special rail with the possibility to start/stop or change direction.
