American Flyer Pike Planner
Attached is the original American Flyer Layout Pike Planner. This essentially was a modified ruler, graph paper, and scale that enabled the model railroader to design their own layouts.
The Pike Planner was helpful for determining which track pieces were necessary as well as for designing your railroad to come out right the first time. The instructions came with a kit that included plastic parts that made it even easier. The American Flyer Pike Planner could duplicate any type of track whether it be a switch, straight away, curve or half-component. This was essential for any enthusiast.
