Which N gauge Tracksetta templates create which radius bends?

Tracksetta is a term that refers to a tool used for the shaping of flexible track sections, it is sometimes also referred to as a track laying tool. These tools are available for a number of different gauges including N Gauge. When creating a layout tracksetta allows the modeller to dictate the curvature and shape of the track being laid. Effectively, it allows the modeller to ensure that straight sections remain straight and that curved sections are laid at a consistent curve and remain free of kinks and deformities. Curves have to be managed very specifically. If the curve is too sharp or lacks consistency in the degree of turn then it can be difficult for a train to manage it, especially at higher speeds. If not laid carefully these issues could lead to a derailment.
