This is a rail variation that can be connected seamlessly with real rails. I made it myself with a 3D printer because I didn't like the blue standard rails mixed in the layout even though I bought real class Plarail. I've posted an explanatory video on Youtube, so please take a look. https://www.youtube.com/watch?v=OL96wNKz048 This is a set of point rails (R-13 real rail compatible) for switching between single and double tracks, and crossing rails that can be replaced with double-track width rails. All joints are concave, so there is no distinction between point rails R/L. Please combine the included convex-convex joints as needed. Set contents Real-style single/double track point rails x 2 Real-style double track crossing rail x 1 Convex-convex joint parts x 10 *This product is a personal production part made with a 3D printer. Please be aware that there may be stripes, color differences, and surface roughness due to manufacturing reasons. *PLA, a plant-based plastic, is used for the material. Please be careful as it is easily deformed at high temperatures.
