Pardon me if I am being something of a newbie here, but I have a couple of questions about layout design.
Thanks! Dean
The typical up-and-over figure eight layouts found in toy train sets have grades of about 3.5%. It's workable, but the pulling power of locomotives can be seriously compromised on such steep grades. (Of course, figure-8 layouts by nature are small enough that long trains aren't a possibility.) Many modelers prefer limiting grades to about 2% or so. The grades are still noticable, but not so steep that they seriously limit train length.
