Atlas O layouts





		last updated: June 25, 2006

Ever wondered what the layouts on the Atlas O 21st Century Track poster really look like? Would you like to construct one of them, or use them as a basis for your own layout? Then the Atlas O Example Layouts pack is for you.

There are 36 layouts in the Atlas O examples pack. These include all of the sample layouts on the Atlas O 21st Century Track system folder. Some of these we have altered to reflect the reality of designing a working train layout --- you cannot just cram sidings into every vacant area and still have a viable design. There has to be space left for structures and scenery that tie all of the operating aspects of a successful train layout together.

Most of the layouts are based on O-54 curves; a few of the larger ones have an O-63 or O-72 mainline, while some of the smaller ones use O-36 curves. All of the layouts are complete with scenery and structures. We have restricted ourselves to using only the Atlas track and the O-scale Accessory library structures in these layout designs. You could, of course, substitute your own scratch-built items, or scale items from other manufacturers such as Lionel and MTH Electric Trains.

You can purchase the Atlas O Example Layouts from R & S Enterprises for $19. They come on a CD complete with an explanatory help file and an installer designed to interface with RR-Track v4.02. A copy of RR-Viewer v4.1 is included on the CD with viewer libraries that display all of the Atlas O examples (these libraries are not compatible with RR-Track v4.x). RR-Viewer v4.1 allows the user to display in both 2D and 3D any of these layouts, study their component list, and print them (changing them with RR-VIewer is not supported).
