There is an art to building complex models using Lego. As with miniatures and other scale models, actual accuracy is limited only by the artist’s imagination and skill. That’s what makes the creations in this video so amazing. Not only do they look realistic, but the movement is very lifelike.

This video showing the Lego factory was featured on the Beyond the Brick YouTube channel. Starting with a giant inline six-cylinder marine engine complete with moving pistons and rotating crankshaft. The valvetrain moves up and down like the parts of a real two stroke motorcycle. You can almost imagine him driving a huge cargo ship, crossing the ocean with thousands of cars on board.

The turbocharged i6 isn’t the video’s only appeal. Next, the 40 wheeler heavy duty tractor-trailer loaded the other ship’s engines and took off. The entire operation is realistic, from loading and securing cargo onto the flatbed, to the individual suspension drives of the transport wheels.

The last engine is a V16 diesel powered emergency generator. It is so accurate right down to the control panel that turns on the generator and regulates the engine speed.

All of these machines were created by Stefan Weinert. Based on his bio is on Rebrickable, he likes to build his own truck models and purely working models like gearboxes and motors. At one time, he was driving heavy trucks, which is why he was so enthusiastic about them.

Weinert is a purebred, refusing to use 3D printed or DIY mechanical parts. He also avoids modifying Legos, including gluing, drilling, or filing them, to change their shape or appearance. In addition to her YouTube videos, she sells complete instructions for her creations so you can make your own.

Beyond the Brick was founded by Joshua Hanlon in 2011. It started as an audio-only podcast before expanding to feature talented Lego builders and their incredible creations. The YouTube channel has over a million subscribers and showcases unique creations from engines and machines to historical recreations and even some Rube Goldberg contraptions included for good measure.
