What is Rail Cube?

Rail Cube is a groundbreaking STEAM toy that transforms learning into a hands-on adventure. Rail Cube features five interchangeable cubes, allowing you to design and build dynamic three-dimensional courses for a mini train to navigate. Mix and match the cubes to create your Magnetic Monorail track set and watch as your mini train brings your imaginative designs to life.

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.

What ages is Rail Cube for?

Rail Cube sets are for ages 3 and up, and grown-ups love building too. It has small parts, so it is not for children under 3.
