The Kato M1 Track Set is our most popular N set and is perfect by itself or as a core unit for further expansion into N Scale trains. This complete oval features our Kato Unitrack that is remarkably simple to assemble and disassemble as many times as needed in the construction and deconstruction of your layout. The box it's packaged in is designed for reuse and comes with a carrying handle and storage drawer where you can keep your model trains and/or accessories. In addition the set features a Kato SX Power Pack, a grade crossing/rerailing track, a rerailer ramp, and a giant track cleaning cotton swab!
