Mezmerizing Infinite Looping Train

Interesting Engineering

James Risner, a train enthusiast attached a long string of train carts and locomotives together to create a bi-directional infinite spiral with Ho scale trains. The seven locomotives can change the direction of the train rather quickly, reaching high (scaled) speeds. However, as for the purpose of the apparatus, we are still looking to find one. Nonetheless, if you have not already seen this hypnotic video- we hope you enjoy!
