David Smith, an enthusiast from New Jersey, has created the world's smallest railway station with a train of five cars.
This train is 35,200 times smaller than a real one. And it is able to move along the circular "railroad" through the tiny tunnel. What's the secret? In fact, the train is only an illusion. Cars are cut into the edge of a plastic tube.
The tube is rotated by a small little motor and it seems as though cars are moving (see video)
