SCARM Tutorial #2-04 showing the design of a Folded Dogbone Layout With Twin Reversing Loops
Attached is a SCARM Tutorial specifically for the Atlas O scale system
A "how to" tutorial using SCARM for designing layouts using the ATLAS O track system. This is in PDF format (not video) and offers time saving hints when designing with SCARM. The tutorial can also be printed from the PDFs.
This layout design creates a folded “dogbone” with twin reversing loops. The layout provides an elevated section with an elevated crossing. The rail to rail track elevation is 7.2 inches at the crossing point.
