This video is from 4D North End Clinic featuring a presentation on logging operations by Russ Segner on 2 July 2020. Russ models in Sn3. He starts the clinic with a brief introduction of his layout's track plan, then some excellent video shots of a long train moving from camp to mill on his layout, and then a slide show giving an overview of the key elements of modeling a logging operation. At the end he answers a few questions from the audience.
