Abstract: In a toy railway system, a switch, a device for reversing the direction of movement of a toy train, and an uncoupling device on the track are each actuated by bellows in a pneumatic actuator assembly connected to manually expanded and contracted bellows in a bank of remote control devices by flexible hoses.

Abstract: A toy road system includes a helical, ascending roadway fixedly mounted on a base and coaxially enveloping a column rotatably mounted on the same base. A slide is axially freely movable on the column, but secured thereto for joint angular movement. A permanent magnet on the slide may couple a toy vehicle carrying an armature to the slide so that the slide rises along the column and a coupled vehicle moves along the ascending roadway while the column turns. A descending roadway connects the two ends of the helical roadway for descent of the uncoupled vehicle by gravity.
