This model is a close approximation of the 24" gauge log bogies (disconnects) located at Timbertown in Australia. This model is designed to accept two 14"-15" diameter wheels on a 1.165" long axle of 3/32" or 2mm diameter. The undersides of the model beams are hollowed out so that lead shot can be epoxied into the recesses to provide mass. This also significantly reduces the cost of the model. Wheels are not included in this model. Coupling is via link and pin.
