3B train is a site dedicated to providing 3D models of trains in the "B train" (Bトレイン) format pioneered by Bandai.
This "B train" format of trains limits the length of each train car to 6 cm regardless of their realistic length while retaining N-scale (1/150) width, height and features.
While a large amount of B train models have been produced by Bandai since 2002, there remains a multitude of models yet to be rendered in this format. By the end of 2018, Bandai decided to reduce the number of new products. 3B Train seeks to fill this gap by providing new models that you can easily print to keep the B train world growing! We produce models of new trains or trains that have not been produced in the B Train format by Bandai.
