N Scale is a model railway scale that represents a ratio of 1:160, meaning that one unit on the model is 160 times smaller than the real-life object. This scale is popular among hobbyists because it allows for more detailed layouts in smaller spaces compared to larger scales like HO Scale or O Scale. Trains and accessories in N Scale are typically smaller than 1 inch in height, making them ideal for compact model railroads. N Scale offers a wide variety of locomotives, rolling stock, and scenery options, allowing enthusiasts to create intricate and realistic miniature worlds.
