The patented component allows connections in all directions, enabling trains to easily pass crossings and creating creative track layouts. Thanks to the side wings, the adapter is safe for children under 3 years old and cannot be swallowed. At the same time, it is compatible with all common wooden railway tracks and building block brands, allowing different play worlds to be easily connected.
