Thank you Paul, I use Xtrkcad right now. I'm a freak who gets a lot of pleasure in designing these layouts that God knows when I will build. And I thought 1% grade was 1" rise 12'? If you have enough room for a long enough mainline, I say "go for it." It would be useful to do a rough sketch in CAD so you can see exactly what type of gradient you'll have. But remember: A 1% grade on an HO scale model isn't nearly as severe as a similar one on the prototype, since equipment weights don't really scale down proportionally. Operationally speaking, it shouldn't be a problem. (1% grade is a change of 1 inch over roughly the length of a 4x8 piece of plywood) Your other concern is how much space between decks are you willing to go with. If you're willing to go with a smaller space, then you can reduce your grade and/or mainline run between levels. - Paul, whose layout will have a constant 1% climb... and it's not even double deck :) The Erie Lackawanna Mailing List http://EL-List.railfan.net/ To Unsubscribe: http://Lists.Railfan.net/erielackunsub.html ------------------------------
