How do the pieces go together?
Connect with a click, disconnect with a twist! The blocks snap together, so kids can build, change and rebuild their track again and again.
Can the train really go upside down?
Yes! Rail Cube is a magnetic monorail. The power of magnets keeps the mini train on the track, so it runs up, down, sideways and upside down.
How does the Mini Train charge?
Every Mini Train comes with a USB cable, so it can stay charged up and ready for adventure.
Can I combine sets?
Yes. Every Rail Cube set, kit, block and train works together. Combine sets to build bigger tracks with more loops and levels.
What does the Program Note do?
The Program Note is your train’s memory keeper. It lets you record your favorite track designs so you can build them again.
