V scale (model railroading)

In model railroading, the V scale refers to a specific scale ratio used for modeling trains and tracks. Specifically, V scale denotes a scale ratio of 1:220, which means that 1 unit (e.g., inch or centimeter) on the model represents 220 units on the real train or track. V scale is smaller than the more commonly known Z scale (which is 1:220) and is used primarily for highly detailed models in a limited space.
