4DBrix Modular System
Modular Switch Track and Railyard System available for pre-order
Thanks again to all our backers for supporting us on Kickstarter! We have made 11 different parts that work together in a modular way to make a variety of switches and railyards, as well as a bumper track. We are still busy fulfilling pledges, we are now half way. We will ship pre-orders straight after.
In the meantime, we have been working on our next Kickstarter project which we will launch in the coming weeks, stay tuned!

Automation as easy as 1-2-3
1 - plug in your 4DBrix controllers, motors, traffic lichts or train detection sensors
2 - open nControl software (available for free here)
3 - automate!
You can control your layout by clicking on the tiles on your screen. If you feel a bit more experimental you can add intelligence to your layout with one of our demo scripts or your own code. And if you're an Arduino expert you can also use your own DIY controller!

4DBrix 3D Printed LEGO Accessories Customer Corner
We are in awe of BrikLoco's MOCs. We are proud to have had a little part in it as we have developed the round nose base for his creations.

"After 30 years, it's exciting to see the resurgence of the LEGO Monorail (...) it’s 4DBrix Monorail Extension Cars that have piqued my interest. Originally LEGO monorails where limited to just two cars, but with 4DBrix Extension Cars you can make endless monorails. I've purchased a number of cars, especially the new Round 20-Stud Monorail/Train Base, as it’s a great chassis to build my Vintage Streamline Trains. 4DBrix also offers Motor Covers with extra studs and in more colors than LEGO." BrickLoco

Those awesome models and many more (we feature some of them with our rounded base, extension cars and motor covers in our shop) are for sale, contact

Newest Monorail Products
Monorail Train Base Rounded 20 studs
Build you own custom train base with rounded end to replace the Monorail train base. It fits either at the front or back of the train. The bogey with two pairs of wheels is mounted on low-friction stainless steel axles.
Short Diagonal
The short diagonal complements the long diagonal for 45 degree turns. The short is especially useful to create more space between a switch and a curve. Like all monorail tracks, available in classic light gray, black and white.
The new stanchion concept can lift your monorail tracks to new heights! Each part is 5 bricks high and you can stack them up to 20 bricks (for now :-). Lock them into place at the bottom for a stable build. Available soon in our store.
More Monorail
You can discover more about a person in an hour of play than in a year of conversation.
