Power is supplied by an A-47 motor with gearbox enclosed in a housing to keep little fingers out. The top of the housing can be removed for service by removing 4 screws which go into captive nuts (Meccano collars). The wide pulley that drives the big wheel is made from a flanged wheel Z and a bush wheel BT. The driving belt was made by my wife Kim. It is a black drawstring cord (probably nylon) from an old pair of sweatpants (her idea!), with the ends sewed together. The belt passes all the way around the small pulley once, and the tension is adjusted so if the big wheel is stopped the belt will simply slip. Adjust is made within a small range by putting spacers under the motor housing.

The motor power cord is connected to an electronic timer and pushbutton. When a kid (of any size!) pushes the button, the wheel runs for about 2 minutes and shuts off automatically. A ground fault circuit interruptor is included and the motor is properly grounded.

A ticket shack and boarding ramp were added for more interest. There are 8 cabins, each one with a roof made by Joe Long. The whole thing is mounted on a piece of 1/2” plywood about 30” x 40” and painted red.
