Reply to "What is a good % for maximum grade"

3% is informally considered to be the maximum desirable grade, though as mentioned the post war trestles were more. The grade percentage figure in SCARM, the layout design CAD tool, changes colors at various percentages of grade (Green, yellow, red). At 3% and over it turns red. At higher grades engines work harder and sometimes slip or one has to run shorter consists. Well lubed wheels on cars can help.
