"N" Scale model trains get their name from the rails they run on, which are spaced nine millimeters apart. They are about half the size of the more common "H.O." (half "O") scale model trains, and only a quarter of the size of the Lionel "O" scale type. The smaller N Scale trains allow greater amounts of scenery to be created for a more true-to-life look. Smaller, more portable layouts are easily created with N Scale, and much longer trains are possible than in most other scales. 

What is NTRAK? 

NTRAK is an international grass roots association of model railroaders which has created a set of standards that anyone may use to build N Scale modules, or layout sections. These sections join together to form large portable layouts like the record-breaking layout that was at the Dulles Expo Center on August 7 and 8, 2004. They also connect together with other folks who follow the NTRAK Standard the world over. The modular layouts have the flexibility to fit into areas of different size and shape, from warehouses to small bedrooms. Since one builds only a small section, even those who live in townhouses or apartments can enjoy model railroading. NTRAK layouts offer close up viewing, correctly proportioned scenery, and maximum train action. NTRAK layouts allow long trains of 50, 60 or even 100 cars! The NTRAK Standards are available from the national NTRAK organization in the "Module How-To Book." Copies of these standards are available from the club.
