Okay, I'm diving into this. Switching from HO to N. So long HO people on the other forums. Just kidding. I'm just getting a 4 axle diesel that I like for now, so radius isn't an issue in my space. I have a couple questions. Do these little buggers pull up a 2% grade as well as HO, or should I get 1% inclines? For now I only plan on running the one engine with a handful of cars. It won't spoil my track plan if I have to switch. 1% is a 1 inch increase in height over 100 inches, correct? What height clearance do I need to over another train? This may affect my plan. Can I use my DCC system with this? I have a MRC Prodigy Express. There seem to be a limited number of DCC equipped diesels out there, as far as I could find. Is this expected to increase as decoders can be made smaller? I have an L-shape space that is 6' deep and 7.5' wide. Are there any resources to check out track plans? What are the good web sites that sell a wide variety of N stuff? Thanks for taking the time to read this and even more for responding. By the way, trainut, I loved your coffee table layouts, but I'm leary of the glass even if it's plexi. Not because of the kid, but because of me. Plus I found space (read that as "got permission from the wife") to put up a small layout. This may be the only forum I've been on that I haven't seen a childish argument or people who think they know it all. Thanks all!!!!!!!!!
