This miniature monorail stays upright with the help of gyro stabilization
Reading Time: 2 minutesMost monorail systems, like the kind at Disney and in Las Vegas, stay upright because the “rail” is actually a very wide beam. The car’s load tires (often literal truck or trailer tires) roll on top of that beam and guide tires clamp the sides of the beam, preventing the car from…
