I have 35 foot run that needs to rise to 18 inches, I need to know is 4.5% +/- too much for a run 35 feet with curves. Basicly I have a center island that I want to build. I will have a 28" rad. half circle as part of the hill. reason I ask this is because I have had problems in the past with Double Stack cars tipping when I have 70+ cars on a train. Any insights would help me especially from people that own large size layouts. Thank you to all that reply. <br />Ross <br />Spokane, WA
