You might want to take out your magnifying glass because the model train set by David Smith of New Jersey is just that tiny. So tiny in fact, that Smith’s model is being touted as the world’s smallest train set.

Just 0.2-inches wide, the train set is “35, 300 times smaller than a real one,” says Engadget, and cost $11 dollars to make. It also works like a real train set—although it’s really a rotating tube underneath the set that makes it move. Watch the video to see the world’s smallest train set in action!
