In this episode host Chris Chianelli visits the historic Georgetown Loop Railroad in Georgetown, Colo. Set among the Rocky Mountains and crystal-clear rivers, this historic railroad crosses water several times on its passenger route. Adding water features to a model railroad is relatively easy, and Chris introduces a modeler in Kansas City who has taken this art form to a new level—adding water features such as ponds, rivers and even a water wheel. Adding water features takes the model train layout to a new level. Later in the workshop a guest joins Chris and, together, they demonstrate how to make a riverbed on a model train layout. This can be achieved using acrylic paints or ground foam.
