When you get into model railroading, you quickly learn about model train scales. Every model train that is produced has a scale letter associated with it, such as: HO, O and so forth. The scale lets you know how true to life it is and more importantly, the physical size of the train itself. The scale refers to the size in comparison with the real thing. For example, 1:220 means the real version of the model train is 220 times larger. If you are a newcomer to model trains, the amount of space will be the first factor in determining which scale to go with. For the hardcore model railroader, mixing scales is a great joy when space permits. Lets take a look at some of the model train scales and minimum space requirements.
Z Scale trains are 1:220, which means they are very small. I call these cute trains and they are perfect for those with an extremely limited space. As with any scale, you can expand the layout as large as you want to go.
Next up is the N Scale, which is 1:160. N scale trains are semi-popular and are great if you want your focus to be on your layout and not the train itself. They are small as well, so you can fit these trains into minimal...
