Thought I'd post a picture of my NSWL S/P #1 HOn3 diesel. I put a 3' section of HOn3 track on a 2" X 4" and then raised one end to see how much of an incline this little monster could handle . Due to heavy weight and very low gearing, this little mountain-climber would make a Shay-driver happy. I don't know a lot about the histrory of the Southern Pacific's narrow gauge, just thought I'd show the loco. Does anyone run one of these on their layout?
