I am a novice and in the planning stages of building my first permanent layout. Question: Am I taking on too much to include changes in track elevations versus keeping everything on the same plane? I recognize the maximum slope needed and have room to have a raised section, but concerned that there are other factors not being considering. My is plan for the "up and down" loop to be basically an oval with 72 inch curves to run passenger trains with sidings on the front and back stretches. I greatly appreciate everyone's input and advise.
