Model trains are sold in six different scales. The scales include G, O, S, HO, N, and Z. The most common model train scale in the United States is HO scale. It is also the most popular scale in Europe, the United Kingdom and Asia. The HO scale is 1:87 which is smaller than the G, O and S scale but larger than the N and Z scale. HO model train pieces are readily available at most hobby and craft stores.
