World’s Smallest Working Train Model

The world's smallest operational train set is a real miniature object, it is built on a scale of 1:35200, and measures just 1/8 of an inch x 1/4 of an inch. The best part certainly is that the set is functional, even with that small size. Made by David Smith, the model has a five-carriage train traveling around an oval route.


Powered by a standard two-inch-long rotating motor head and carved out of mouldable plastic, the model train cost Mr Smith just over L6 to make. “To get a sense of scale you have to remember that the River Branch project is being built to the scale of 1-220,” Mr Smith added. ‘It has taken up two-and-a half-years of my life and is going to be very impressive once it is finished.
