In this episode, I wrap up a few loose ends before we finally get to layout construction. First, I finish off explaining a wide variety of railroad-related terminology, going into all the depth you would need to know about what most major railroad components are and how they work. Then, I list off and describe all the tools you would need to build a model railroad. Importantly, I then follow this up with modeling safety, and close out the episode with a little bonus, proving that model railroading is not just for nerds.
