Great tool! With Atlas Track Planning Templates, beginners can visualize the size and shape of their layout before they begin building; advanced modelers can determine whether or not a complex layout design will fit together the way they planned. The templates are exact paper replicas of currently available code 100 Atlas track, switches, bridges, piers and viaduct. Each template can be copied on a copy machine to produce the amount of track pieces needed for a given layout. The templates can then be cut out and positioned, like pieces of track, into the desired layout shape.
