The Atlas Z Scale Gunderson Multi-Max Enclosed Auto Rack is based on cars introduced in 2013. Greenbrier Companies introduced its new design of 89' auto rack, the Multi-Max(TM). The design allows for changing configurations from a Bi-Level to a Tri-Level (and back) without adding or removing decks. The racks are fully compatible with existing 89' auto racks. Most of the racks have been built on Greenbrier specially designed 89' flat cars. The cars are commonly seen in cuts of other similar autorack cars or insolid unit trains of autorack cars. By the mid 2020s, almost 10,000 cars (with racks) were running on North American rails. Atlas Z scale rolling stock features crisp painting and lettering, perfectly recreating the colorful paint schemes found on their real-world counterparts. Features include truck- mounted operating knuckle couplers, blackened metal wheelsets for smooth operation and accurate painting and lettering. Recommended radius: 8-2/3" 220mm Check out the entire line of Atlas Z Scale products.
