I call that the "ear on the carpet" view...my favorite.
Joe, I agree. Viewing the trains from an O scale persons perspective is the best. We usually view our layouts from above like we are in an airplane but getting down to "eye level" makes even our non scale toy trains look very realistic. I have my layout height set so that I view the trains from "see level" when I am operating them sitting in my chair.
