Amazing Automated LEGO Roller Coaster with Switch Track - The Hair Razor (3 train operation)
12This is (as far as I can tell) the first fully Lego roller coaster* with automatic switch track, which adds, advances, and removes cars and block zones! A barber in Lego City wanted a faster way to style his customer's hair, and so he built the Hair Razor! This marvel of engineering cuts, washes and combs everyone's hair in less than 30 seconds! No refunds if it turns your hair red or removes it all! Ice cream, Hot dog, and photo stands were also added under the coaster. For this build, I used the Lego Education Spike Prime Hub (Which is exactly the same as the Mindstorms Hub), and the Technic Hub, along with Motion Sensors, Motors, and Powered Up Lights for the camera flash, and programmed with PyBricks.
