I am just getting into On30 , what is the max grade for a climax or a shay with about two ore cars. I would like to get up six inches in 96 ins or 120 inches. thanks

No Prob! Hey, Wab - welcome to the Guage. If you divide the rise in height by the length of the rise, you'll get grades of 6.25 percent and 5 percent respectively....grades that will not even make a Bachmann Climax or Shay break a sweat.

My Shay will pull 5 boxcars up 6.5% starting out on a 18" radius curve. 6 cars, and the front truck will derail in the curve. After the curve, and on a straight away, it will pull 8 boxcars up the grade with no problem.
