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 wind-up vehicles, the wind-up key may collide when trains pass each other. Please run the vehicles so that the wind-up key is on the outside. 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. Due to the unique sleeper design, it may not be possible to combine with some diorama parts. *This product is a personal production part made with a 3D printer.
