CLINIC - Flex Operations


Flex Operations - Concepts to define your model railroad’s purpose and scalable operations.

This clinic will focus on key topics to help define, design, and tailor operations on your model railroad. Using my Michigan Interstate St. Clair Subdivision as an example we will walk through the evolution of layout operations starting with a defining question; "What is your model railroad's purpose?". From this question we look at different aspects and approaches to operations including design, industry selection, car management, and train management. Key takeaways from this clinic use the F.L.E.X. acronym to provide a simple reminder as you implement or improve your model railroad operations.
