Abstract

Miniature vehicles operable on a slotless track have their front wheels disposed on a tie bar assembly mounting a permanent magnet. The permanent magnet is disposed to be attracted to either the right or left pole piece of a solenoid. First and second operator applied steering voltages activate a zener diode to switch current through the solenoid to effect right or left steering and lane changing by the vehicles.
