This is a rail set that allows you to easily create a double-track layout with Capsule Plarail. Since it is longer than the official rails, stable running can be expected. Of course, it can also be connected to official rails. Set Contents 2x Long Straight Rail (convex/concave) x4 45-degree Double-Track Curved Rail (convex/concave) x4 45-degree Double-Track Curved Rail (convex/convex) x2 45-degree Double-Track Curved Rail (concave/concave) x2 When using a wind-up train, the wind-up key will collide when trains pass each other. Please run the train with the wind-up key facing outwards. Unlike official rails, these rails can only be used on one side. When creating layouts such as S-curves, please use rails with convex/convex or concave/concave joints, or use official rails.
