Working with individual track sections has its convenience, but for free-flowing original track designs, flex track is a better option. Working with flex track takes some care and practice but with a little patience and know-how, even a beginner can pick it up quickly.
Flex track is a bendable track section that can be shaped to any radius. One rail is fixed while the other slides in the cradles. Sections come in 18 to 36 inch lengths in N, HO, and O scales. Narrow gauges are available too.
